Could someone point me in the right direction. I am building a tool for scultping. I want the mouse cursor location to effect the points on a given polygon object. I have gotten so that I can display the mouses coordinates on the viewport with this.

how would I now get the points on the active object to react to the location of the mouse cursor?

I really just need to be pushed in the right direction. Certainly don't want someone to do it for me.

Thanks,

Check out the ViewportSelect class. It is used the determine which points, edges or polygons are near the mouse cursor.

Btw. that's quite an ambitious project, good luck.

cheers,
