How can i draw a V-belt as a separate part in SolidWorks?
1. Get section dimensions for your belt:
for instance: http://www.powerdrive-belt.com/new/products.asp?x=1&id=3&id4=1
2. Draw two circles represent your pulleys.
3. Insert plane perpendicular to line.
4. On that plane draw section of your belt. i took SPB Belt
5. Use sweep feature and belt ready.
