Hit Shift+A => cylinder with 32 vertices, radius of 1.9, depth of. Press SHIFT+SKEY, from the popup menu, choose "Cursor to Selected", to put the cursor at the center point of the existing tire. (The scene should be in front orthographic view - hit NUM1 for front view, NUM5 for orthographic if not). Hit AKEY, once or twice till all the wheel's vertices are selected. Now press SHIFT+EKEY to Crease these edges - type 1.000, and press ENTER, or hold CTRL to pull in steps till you see 1.000 in the status bar at the bottom of the view window. This will select all of the inside edges, as well as the triangles on the side of the tire, as in the picture below. Use the scroll wheel to change the circle selection size to be in the center of the tire, between the inside and outside edges. Check that Limit Selection to Visible is off (that is, so you can see the extra edges and vertices).īring up the circle selection tool ( AKEY to unselect all, then CKEY). Switch back to orthographic mode ( NUM5 to toggle) if need be then go into to Edit Mode. The tire will now look like a bead necklace.Ī little creative use of creases will restore our tire.
Return to Object Mode, and apply a subsurf modifier (use the Modifier menu in the properties header - it looks like a wrench) click on "Add Modifier" and select Subdivision Surface - select VIEW level 1 or 2. Now it's time to make the tire look like a rugged tire. Now select all with the AKEY and remove doubles by pressing the WKEY -> Remove Doubles.
You may either type in -1.2 and hit enter, or hold SHIFT CTRL and move the mouse to extrude the faces until the sides come in -1.200 units. Select all vertices, hit the E Key and directly after that the ESC key to make the new faces, then Alt+EKEY and choose "Individual faces" and extrude the individual faces into the circle. Switch to orthographic mode ( NUM5 to toggle) and then go into Edit Mode. The "align to view" option rotates the cylinder so that it is aligned to the view space.Ĭreate the inside of the tire
By default, objects are aligned to the global space axes. Hit NUM1 to set front view (XZ coordinates), then delete the cube.Ĭreate the outside of the tire Īdd a cylinder Shift+A > Mesh > Cylinder then in the tool shelf use 32 vertices, set the radius to 4, depth to 3, choose Cap Fill Type: "Nothing", and click on "Align to view". Switch back to orthographic view ( NUM5) to edit. You may also want to rotate in the XY plane using scroll MMB or NUM2/ NUM4. Feel free to switch to perspective view ( NUM5) from time to time to see how things are developing. We need a tire that can handle any obstacle in its way.ĭuring this tutorial we will be primarily using orthographic view. They're not too sleek but rather rugged for all kinds of terrain.
