FazBear Posted June 21, 2006 Share Posted June 21, 2006 Following a PM I received last night regarding the following image on this thread http://www.cadtutor.net/forum/viewtopic.php?t=7827, I have put together this tutorial to explain how I got the tread on the tyre. I will try do this as simple as possible because its quite lengthy, please feel free to comment if you know a better way to do this as I am always open to criticism. Anyway this is what I posted This is the PM I received Subject: tire tread Nice rim. I was wondering how you did the tire tread? So here we go: 1. First of all create the tyre diameter and width 2. Array a line from the centre of your tyre; this will give you the angle in which you will need to rotate the tread (explained later). 3. Draw the lines across from one section to give you your linear spacing between treads. 4. Create the pattern of tread; I have done this as rectangles for simplicity. Allow a small amount for the gaps in the tread, I left 1mm top and bottom and 2mm gaps across. 5. Create the tread profile (major and minor); this will create a void later. Copy the geometry as you will need it later. 6. Draw a rectangle from the CL to well clear of the tread, Make the rectangle a region, and the Major/Minor profile. 7. subtract the Major/Minor Region from the Rectangle region and revolve the remainder 360deg about the CL, This gives you an internal void. Make the treads regions and extrude them also. 8. Make sure the treads are central to the CL then subtract the revolved void away from the extruded treads 9. Separate the treads as they group when subtracted together and then erase the excess leaving only treads. 10. Create a region using the copied Minor tread profile from op5 and revolve that about the CL 11. Position the treads over the minor tread profile 11. Array the treads about the CL the same amount of times as you did in op 2, to ensure the treads are equidistant. 11. Finally union all them together and Voila!
