Hey guys, and welcome to the second part of the bicycle 3ds max modeling tutorial. In this 3d modeling tutorial we will be 3d modeling the frame of the bicycle. In the first part of this series we did the bicycle's fork. So, before we start this 3d modeling tutorial i must say don't hesitate to comment if you stumble upon any problems. I'm here to help.

Step 2: So you don't get confused with the units setup change it so that we all work with the same type. From Customize, click on Units Setup, select Generic Units and International, click OK. I've use to work with the metric system, but I've found out the with generic it's easier for everyone.
Step 3: With the Front viewport activated(you can see a dark yellow line around it), select Create, then Geometry, select the plane, change the Length and Width Segments to 1. In Keyboard Entry set the X,Y,Z coordinates to 0 and the Length and Width to 150 and click Create.
Tip: To change the view in the viewprot from Wireframe to Shaded just click on Wireframe in every viewport in the top left corner and change it.
Step 4: Press "M" on your Keyboard to open Material Editor, from Modes in the top left select Compact Material Editor, Select any slot you like and click on the Square next to Diffuse, chose Bitmap and open this file(click to open).
Step 5: With the Plane created in step 3 still selected, click on "Show Shaded Material in Viewport" and the "Assign Material to Selection". This will be our reference. We can do it without the reference but it's much easier for our 3d modeling process to do it like this.
Step 6: Now change the Viewport to Top, select it or simply change the active one by pressing "V" on your keyboard and selecting it. From Create, Geometry, select the Cylinder, changer the Height Segment to 2, Cap Segments to 1 and Sides to 8. In Keyboard Entry set X to 0, Y to -30(so the cylinder will be in front of the plane), Z to 0, Radius to 3 and Height to 23. Click on Create.
Step 7: Maximize the Front Viewport by pressing ALT+W on your keyboard or by using the viewport navigation tool in the bottom right corner. Using the Select and Move tool and the Select and Rotate tool(be careful to rotate it only on the Z axis with the yellow circle) position the Cylinder like you see bellow.
Step 8: Change the Viewport to Perspective by pressing "P" or "V" on you keyboard. Right Click on the Cylinder and Convert it to Editable Poly.
Step 9: In the top right corner go to Modify, expend Editable Poly by clicking on the "+" sign, select Polygon selection mode, holding down CTRL select both the top and the bottom polygons and press DELETE.
Tip: If you do something Wrong in this 3d modeling tutorial just press CTRL+Z to undo.
Step 10: Change the Viewport to Front, in Polygon selection mode select the top half of the Cylinder and using the Select and Move tool Copy it to the left by holding down SHIFT. Chose Clone to Object and click OK.
Step 11: Now select the newly created object. To do this is by first exiting the Polygon selection mode, you can do this by clicking on Editable Poly. Now click on the new object to select it. We need to center the Pivot Point so that the Move, Scale and Rotate tool are centered. Go to Hierarchy, activate Affect Pivot Only and click on Center to Object.
Step 12: Now using the Select and Move tool and the Select and Rotate tool position the object like bellow so that they intersect.
Note: Remember, ALT+W to change between 1 and 4 viewports.
Step 13: Go to Modify and enter Edge selection mode. In Edit Geometry activate the Cut tool and create a new Edge by left clicking first on one edge and then on the other like bellow. Right click to finish, move around and start again.
Tip: The Cut tool has 3 options: 1) When you click on vertices you see a small square around it. 2) When you click inside a polygon you will see a a bigger square around it and 3) When you click on edge you will see a small rectangle. Option 3 is what you need to use, from edge to edge.
More tips: Do remove an edge you don't like press Backspace, if you want to Remove the with with the vertices hold CTRL and press Backspace.
Super more tips: Be careful when you cut to another vertex not not cut very close to it and not notice, you will have 2 vertices very close to each other and it will be a problem when we apply a Turbosmooth modifier. To make sure everything it's OK, click and drag over the vertices and see how many you have selected.
Step 14:Repeat the last step so you go all around the cylinder with the Cut tool.
Note: To toggle between Shaded and Wireframe press F3.
Step 15: Select the other object and go in Border selection mode, select the border inside the other object and move it to the left so they will not intersect anymore.
Step 16: In Edit Geometry activate the Attach tool and click on the other object so they will be part of the same object.
Step 17: Using the Cut tool again in Edit Selection Mode, make new edges so that you connect the back of the cylinder.
Step 18: Go in Polygon selection mode, and select the highlighted polygons and DELETE them.
Step 19: Change the selection mode to Border and select the borders from both sides and click on Bridge. Since we didn't use Bridge before, the default values are good, so click the check mark for OK. You will now have the object connected.
Step 20: Go in edge selection mode, select the edges you see selected and click on the Square next to Chamfer, change the amount to 0,1 and click OK.
Note: To make a viewport bigger put the mouse over the edge of the viewport, you will see a arrow in both direction, click and drag to resize it.
Step 21: In Vertex selection mode, activate the Target Weld tool, and to weld vertices together first click on one and the click on the second. See the image bellow for reference. Remember to this on both side.
Step 22: Repeat all the steps starting from step 10, and create the bottom part like you see bellow. It dose not make any sens for my to do then since they are almost 90% identical.
Step 23: Now Select the Border and move it to the left like bellow using the Select and Move tool.
Step 24: In Polygon selection mode, select the polygons and copy them down holding down SHIFT, chose Clone to Object and click OK.
Step 25: Center the Pivot like we did in step 11, and using the Select and Rotate and the Select and Move tools position the object on the frame.
Step 26: Select the other object and in Border selection mode, select the border and intersect it with the newly created object using the Select and Move tool.
Step 27: The next steps are easy, by now you got this since we did it 2 times already. So connect the Objects, and do the same things like we did before.
Step 28: In Border selection, move the borders like below using the Select and Move tool.
Step 29: In Front Viewport, from Create, Geometry make a new Cylinder with the Radius of 4.25 - 4.3, the Height of 9, Height Segments: 2, Cap Segments: 1 and 16 Sides. Using the Select and Move tool position it like in the next image. Also make the border of the other object to intersect with it.
Step 30: If you followed this 3d modeling tutorial correctly you can see that the edge almost intersect. Don't forget to also convert this cylinder to editable poly by right clicking on it and selecting Convert to -> Editable Poly.
Step 31: It's now time to use the Cut tool again. I know this tool is a bit tricky but with practice you will get the hang of it. If you do something wrong just press CTRL+Z, or delete the unwanted edges by pressing Backspace. Also, if it seams like the Cut tool dose not work, when you Cut to a vertex you probably created one right next to it and you probably now have to very close together, so weld the using Target Weld or Weld Tool.
Hide Unselected by right clicking on the object, and after using the Cut tool you should have something like bellow. As you can see i also deleted the cap polygons.
Step 32: In Polygon selection mode select the highlighted polygons and DELETE them. by pressing Delete on your keyboard.
Step 33:Now in Vertex selection mode, activate the Target Weld tool and Weld the vertices in the direction of the arrows.
Step 34: For the next steps i will only write and you will get one image because we did this before. So, 1) Right click and Unhide all, 2) select the main object and in border selection mode move the border out so they don't intersect anymore and 3) Activate Attach tool and attach the objects together.
Step 35: Now select the borders and Bridge them together.
Step 36: Now select the other border from the top, and holding down SHIFT copy it to intersect with the bottom cylinder.
Step 37: Now it's easier to select the newly created polygons and Detach them to another object. Click OK. It will be easier to use the Cut tool now.
Step 38: OK, so now make the round Cuts like bellow, take or time, even Save your work before. Go in Edge selection mode, activate the CUT tool and make the cuts like bellow.
Step 39: Now to see what we have done, right click and Hide Unselected.
Step 40: Delete the polygons.
Step 41: Now in Vertex Selection mode, use Target Weld to weld the vertices together like below. Follow the arrow for reference. If you got one or more line that i don't have from the CUT tool use Backspace to Delete them.
Step 42: In Edge selection mode, using the Cut tool created the selected edges from below.
Step 43: As wee did so many time, in Border selection mode, Bridge the borders together. You can now Unhide and Delete the previously Detached object.
Step 44: Now let's make a Ring selection of edges in Edge selection mode. Select one edge from each side and click on Ring.
Step 45: Click on the square next to Connect and connect the edges together with 1 segment and 0 Pinch and Slide.
Step 46: In Edge selection mode, hold down CTRL and select the base edges of the intersecting cylinders like you see in the next image. Chamfer the edges with an amount of 0.1. Click OK.
Step 47: In Vertex selection mode Target Weld the vertices like bellow on both sides.
Step 48: Now we need to weld some more, so use the Target Weld again and weld also this vertices on both sides.
Step 49: Make another Ring selection in Edge selection mode like bellow. Select one edge from each "column" and click on Ring. Connect the edges so you have something like in the next image.
Step 50: Change the Viewport to Left and Create a new Cylinder from Create -> Geometry -> Cylinder with the Radius of 1.6, the Height of 8, 1 Cap and Height Segments and 8 sides. Position it like below using the Select and Move tool.
Step 51: y now you should be a master of handling the Cut tool :) so let's make some cuts around the new created cylinder. You should have something like bellow. As you can see I've hided the cylinder.
Step 52: In Polygon selection mode Delete the inside polygons, change the selection mode to Edge, select the 4 highlighted edges and press Backspace(not delete) to remove them.
Step 53: In Border selection mode, select the border and holding down SHIFT copy it to the back of the bicycle frame using Select and Move tool.
Step 54: In Edge selection mode make a Ring selection of the edges from the back so that we can connect the like bellow using the Connect tool with 2 segments a Pinch of -15 and a Slide of -70 so we get something like in the next image.
Step 55: Change the viewport to Top an using the Select and Move tool in Vertex selection mode position the vertices like bellow.
Step 56: Select the back group of vertices and using the Select and Scale tool scale them down in all axis to 60(see bottom row of image).
Step 57: Change the Viewport to Front and zoom in the back of the bicycle frame. Zoom in and using the Select and Move tool position the vertices like in the next image.
Step 58: From Create -> Geometry -> make a new Box with the Length of 5, the Width of 6.7 and the height of 1. Make it with 3 Length and Width Segments and only 1 Height Segment. Convert it to Editable Poly.
Step 59: Hide Unselected to hide everything else besides the box. 1)Go in Polygons selection mode and delete the polygons, 2) Go in Edge selection mode and Bridge the edge and finally 3) use the connect tool after you ringed the edges from the side to create a new edge in the middle.
Step 60: In Vertex selection mode using Target Weld follow the image bellow and weld the vertices together on both sides.
Step 61: Change the selection mode to Edge and make some ring selection and Connect them like bellow.
Step 62: In Polygon selection mode delete the 8 polygons you see selected.
Step 63: Unhide all and using the Select and Move tool move the "box" so it dose not intersect with the bicycle frame.
Step 64: Select the Bike frame and Attach the box to it like we did before. Position the box in the Top viewport to be on the middle like bellow. Now select the bottom border from the box and the border from the frame and bridge them together.
Step 65: Working in the Front viewport in Vertex selection mode use the Select and Move tool and reposition the vertices.
Step 66: In Edge selection mode Chamfer the inner edges with an amount of 0.1.
Step 67: Select the polygons and holding down SHIFT copy them up. This time Clone to Element and Click OK.
Step 68: Using the Select and Rotate tool and the Select and Move tool position the new created polygons(or element) like you see bellow.
Step 69: In Border selection mode, Bridge the borders together and using the Select and Move tool reposition the vertices like you will see in the next image.
Step 70: Chamfer the edges with an amount of 0.1.
Step 71: In Vertex selection mode, select the vertices you see selected and using the Select and Scale tool scale them down in all axis to 70.
Step 72: Make a Ring selection of the edges in Edge selection mode and Connect them with 3 segments and a Pinch of 50.
Step 73: Now position the border inside the frame so that we can connect them together. Use the Select and Move tool in Border selection mode.
Step 74: Go back to Edge selection mode and Connect the edges like we did before with 3 segments and 50 Pinch.
Step 75: In Polygon selection mode select the intersecting polygons and click on Detach so we can make the cut easier and not do it on it. Leave the boxes unchecked and click OK.
Step 76: Select the bicycle frame again, and using the Cut tool in Edge selection mode make the cuts around the intersecting cylinder like bellow. Remember, to remove a badly cut edge press Backspace or CTRL+Backspace to remove the vertices as well.
Step 77: Hide unselected by right clicking on the object and selecting "Hide Unselected" to see what we have.
Step 78: Now, in Vertex selection mode using the Target Weld tool weld the vertices together in the direction of the arrows.
Step 79: It's time to make some more Cuts in Edge selection mode, look at the next image and Using the Cut tool in Edge selection mode, make some cuts to connect around the vertices from the sides.
Step 80: It's time to do something we did many times by now in this 3ds modeling tutorial. So, 1) In Polygons selection mode DELETE the polygons pressing DELETE, 2) In Border selection mode, Bridge the borders with a TWIST of -1. 3) In Edge selection mode Chamfer the edges with an amount of 0.1.
Step 81: By now I'm pretty sure you know how to use the Connect tool in Edge selection mode, so see the image bellow and make new connection like the highlighted one. Remember, first select the edges you want to connect, then click on the square next to Connect, and use Slide to move the new edges from one side to the other.
Step 82: New forgot to Chamfer some edges, so follow the image and Chamfer the highlighted edges with an amount of 0.1.
Step 83: In Vertex selection mode Target Weld the vertices on the direction of the arrows. Remember to do this on the other side as well.
Step 84: Go on the other side of the bicycle and select the 12 polygons I've selected and Delete them.
Step 85:Now select the polygons from the back, all of them like bellow, and holding down SHIFT copy them to the side and Clone to Object. Click OK.
Step 86: Select the newly created object and Center the Pivot like we did before. Using the Mirror tool mirror the object in the Y axis and click OK.
Step 87: Now attach the object back to the frame using Attach tool. Using the Select and Move tool move the object to fit in the caps from the previously deleted polygons. Use the on screen move tool first to position it and after that use the numbers of the x,y,z axis from the bottom of the screen to be precise. Take your time.
Step 88: Zoom in the top part to do some Target Welds like bellow.
Step 89: In Vertex selection mode select every overlapping vertex from the object and the frame so that we weld the together. First we do the top part and then the bottom. So Select the highlighted vertices, 12 in total(press F3 for Wireframe view so you don't select any from the Back) click on the square next to Weld and with a small amount like 0.1 you will see a difference of 6 vertices between Before and After.
Note: If you have to many vertices, they probably resulted from the previous cuts, Weld or Target weld does vertices as well.
Step 90: On the bottom part, first Target Weld the to top and bottom vertices. I've already did so it's not seen in the image. Then select the highlighted vertices and Weld the together. From a total of 18 vertices you should now have half.
Step 91: Now its time to make the border's holes thicker. So 1)In Border selection mode select the borders from both sides and using the Select and Scale tool, scale them down in all axis to 90 holding down SHIFT to make a copy. 2) With the borders still selected use the Bride tool to connect them and change the number of segments to 4. 3) Select the edges from both sides using Loop and holding down CTRL and Chamfer them with an amount of 0.05.
Step 92: We now have some 3 edged polygons resulted from the chamfer we did before. To solve this problem simply Target Weld or Weld the highlighted vertices. You will have to repeat this step 3 more times, 2 time on each side, top and bottom.
Step 93: Repeat the last steps for the front of the bike as well. The selected edges are the newly created one, so do your best to reproduce this. I'm very confident the you will mange do it. The tools you need to do this are: Scale and Move tool with Shift to copy, Chamfer with an amount 0.05, and Connect.
Step 94: Now for the seat hole reproduce the selected edges as well. Again, the tools needed are: Scale tool and Move tool holding down Shift to copy, Chamfer with an amount of 0.05 and Connect.
Step 95: For the last step of this 3d modeling tutorial we must add a Turbosmooth modifier from the Modifier list, change the Iterations to 2 and check the box for Isolate Display.
