How can I add ''rough'' surface on my model?
Is there an easy way of adding ''rough'' surface on my model in SolidWorks? See the picture attached.
Depends upon your package.
If you use 3d Max, for instance, you can add a "bump map" for effects.
I have enclosed an example of a crankshaft I created. There is a machined surface and a cast surface. To create the "cast iron" effect I added a bump map to the Diffuse Channel. This map was simply a photograph of sand.
I think procedural maps could do the same effect. Also, in Max you can use "noise" to add a bumpy texture.
