Hi again guys. This is our 6th 3d modeling tutorial of the bicycle 3d modeling tutorial series. In this part we will learn the 3d modeling process of the bicycle's seat. If you have any problems following this 3d modeling tutorial please fell free and comment or ask me any kind of questions. I'm here to help. So let's begin this 3d modeling tutorial.

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: Work in the Top viewport("T" on your keyboard). From Create, Geometry, select Cylinder, Height Segments to 3, Cap Segments to 1 and 8 Sides. In Keyboard Entry leave X,Y and Z to 0, change the Radius to 25, the Height to 400 and click on Create.
Step 4: Convert the cylinder to Editable Poly by right clicking on it and selecting Convert to -> Convert to Editable Poly. From the Modify tab, go in Polygon selection mode, holding down CTRL, select both top and bottom polygons and press Delete.
Step 5: 1) Select the bottom polygons. 2) Holding down SHIFT and using the Select and Move tool copy them to the side. 3) In Hierarchy, activate Affect Pivot Only and click on Center to Object. 4) Using the Select and Rotate tool and the Select and Move tool rotate and position it to intersect.
Step 6: Using the Cut tool in Edge selection mode, Cut around the cylinder to create new lines.
Step 7: With the Cut tool again, cut around the back of the object to connect the edges.
Tip: Right click on the screen and select Hide Unselected to only see the object you are working on. Unhide all to see them all again.
Step 8: In Polygon selection mode, select the polygons and Delete them by pressing Delete.
Step 9: Select the other cylinder. 1) In Edge selection mode select all the side edges. 2) Connect them with 1 Segment. 3) In Polygon selection mode Delete the left polygons.
Step 10: With one cylinder selected, activate the Attach tool and click on the other one.
Step 11: In Border selection mode, select the borders and click on Bridge.
Step 12: Select the intersecting edges in Edge selection mode, click on the box next to Chamfer, and Chamfer the edges with an amount of 1. Click the check mark for OK.
Step 13: In Vertex selection mode, using the Target Weld tool, weld the vertices in the direction of the arrows. First activate the Target Weld, then click on one vertex to start the weld process, then click on the other to finish.
Step 14: Make a Loop selection of the edges in Edge selection mode. Select one and click on Loop then press CTRL+Backspace to remove the edges and vertices as well.
Step 15: Select both rows of the intersecting vertices and using the Select and Scale tool scale them up in the Y axis to 124.
Step 16: In the Front viewport, from Create, Geometry, create a new Cylinder with the Radius of 32, the Height of 75, 1 Height Segment, 1 Cap Segments and 14 Sides. Using the Select and Move and Select and Rotate tools, position it to intersect with the other object like bellow. Convert the object to Editable poly and Delete the Cap polygons.
Step 17: Repeat the last steps to make a connection with the new cylinder like we did before. 1) Cut. 2) Delete polygons. 3)Bridge borders. 4)Chamfer edges. 4)Target Weld Vertices. Use the bellow image for reference.
Step 18: 1) Select borders. 2) Using the Select and Scale tool and holding down SHIFT, scale the borders down in X and Z axis to 85. 3) Bridge the borders or edges together.
Step 19: In Edge selection mode, select the side edges and click on the box next to Chamfer to chamfer them with an amount of 0.5. Click OK.
Step 20: 1) Cap the top border in Border selection mode. 2) In Polygons selection mode Bevel the newly created polygon with a Height of 5 and an Outline of -7. Click the "+" sign. 3) Change the Bevel Height to 2 and the Outline to -7. Click the check mark sign for OK.
Step 21: In Edge selection mode using the Cut tool create 2 new edges.
Step 22: Make a Loop selection of the edges and Extrude them with a Height of -10 and a Width of 0.3.
Step 23: With the same edges still selected, Chamfer them with an amount of 5, check the box for Open Chamfer and click OK.
Step 24: Make a Loop selection of all the selected edge bellow and Chamfer them with an amount of 0.5. Don't forget to uncheck Open Chamfer.
Step 25: Now that we finished the 3d modeling tutorial part of the handlebar's pipe it's time to begin 3d modeling the handlebar. So, from the Modifier list add a Turbosmooth modifier, change the Iterations to 2 and check the box for Isoline Display.
Step 26: In the Top viewport, from Create, Shapes make a new line like bellow.
Step 27: In Vertex selection mode Fillet the middle vertices with an amount of 30.
Step 28: In the Rendering tab, check the boxes for Enable in Viewport and Renderer, change the Thickness to 47 and the Sides to 8. Convert the line to Editable Poly.
Step 29: In Polygon selection mode Delete the cap polygons.
Step 30: Select the edges and Connect them with 2 Segments.
Step 31: In Polygon selection mode select the bottom polygons and Scale them up in all axis to 110.
Step 32: Click on the Mirror tool, change the axis to Y, select Copy and click OK. Using the Select and Move tool reposition the newly created object. Attach them together.
Step 33: Select the middle vertices in Vertex selection mode, click on the square next to Weld, change the amount to 0.1. You should have a difference of 8 vertices between Before and After. Click OK.
Step 34: From the Modifier list add a Shell modifier, change the Inner amount to 3 and Convert the object back to Editable Poly.
Step 35: Select the edges from both side and Chamfer them with an amount of 0.5. Click OK.
Step 36: Go to Hierarchy tab, activate Affect Pivot Only and click on Center to Object.
Step 37: Using the Select and Move and Select and Rotate tools, position the handlebar to fit with the pipe like bellow.
Step 38: 1) Select the top vertices. 2) Using the Select and Rotate tool, rotate the vertices for 10 degrees. 3) Using the Select and Move tool reposition the vertices. 4) Repeat the steps for the bottom vertices. 5) Select all vertices(CTRL+A) and rotate them 10 degrees in the Y axis and using the Select and Move tool reposition the handle inside the tube.
Step 39: The next part of this 3d modeling tutorial is the process of 3d modeling the handlebar's grips. So, in Polygon selection mode, select the polygons and Detach them as Clone.
Step 40: Select the newly detached object and Scale it up to 102 in all axis.
Step 41: 1) In Border selection mode, select the border and click on Cap in Edit borders tab. 2) Select the newly created polygon in polygon selection mode. 3) Click on the square next to Inset, change the amount to 12 and click OK. 4) In Edge selection mode, using the CUT tool create 2 new lines. 5) In Edge selection mode select and Chamfer the edges with an amount of 0.1. Click OK
Step 42: Add a Shell modifier from the Modifier list, change the Outer amount to 2 and Convert the object to Editable Poly again.
Step 43: In Edge selection mode, select the edges and Connect them with 30 Segments. Click OK.
Step 44: Select the edges I've selected and Extrude them with the Height of 2 and the Width of 1.2. Click OK. Then Chamfer them with an amount of 0.5. Click OK.
Step 45: In Polygon selection mode, select the inner polygons from the side and Bevel them with an amount of 15 and an Outline of -2. Click OK.
Step 46: Mirror the handlebar grip using the Mirror tool, in the Y axis with an Offset of 835, select Copy and click OK.
Step 47: Select the first created object, the pipe, and using the Attach tool, attach all other objects together.
That's pretty much it. In this part of the 3d modeling tutorial series we build the handlebar's pipe, the handlebar and the handlebar's grips. We did something basic, but efficient. In the next 3d modeling tutorial we will learn the 3d modeling process for the bicycle's seat.
