Creating new points

The only way to do that is via a boolean operation. If you have an example showing a messy result please send it to me (<!– e –><a href="mailto:richard@amabilis.com">richard@amabilis.com</a><!– e –>) and I’ll have a look at it.

Boolean operations are restricted in what they can do.

The major requirement is that both objects must be solid. If they are not solid the result will be a mess.

Also, due to the mathematics involved you can get a failure depending on the orientation and position of the two objects. No matter what 3D modelling program you use you will get this occasionally. Some 3D programs are better than others at recovering from this and have fewer errors, but ultimately they will all fail occasionally. 3DC tries to recover by stitching faces over the problem areas. Sometimes this produces good results, sometimes not. One possible solution to this is change the position or rotation of one of the two objects. Even a tiny change of .0001 of a unit can make the difference (you can move an object a small amount by setting a manual position in the object properties).

If you don’t have 4.2 I would suggest downloading it since it does have improvements to the boolean operations.

Hello,

I’m having trouble with messy boolean operations (even after triangulating.) So I’d like to go at it manually.

I know I can split an edge, but is there a way to split an edge specifically where it intersects a face of another object? In other words, create a new vertex that splits an edge of object A where this edge intersects a face of object B.

Is there a way to do this? If not, it sure would come in handy.

Thanks,
Clem
