A turboCAD user said when creating rivets dont just draw hole cutting solids (I use cylinders), transform copy them then boolean them out of solids, use a Block Instance. The prog has then only to remember the one and writes faster looking at instances as opposed to each as a separate unique item.,
Just what does that involve when making cutting solids ?
I even use crosses but notice the redraw and speed slows down when I get to place loads of rivets or crosses, certainly the rivet holes all over an item. With rivets being two or three different sizes, then there are the countersunk holes, what is best practice ?
