Extruded and cut letters

[Anonymous]

When I extrude letters into an object for engraving and then take a slice through the object with an offset plane, the letters and their centres show up fine. However, when I put a sketch on said plane and project the object, guess what, only the outside of the letters show up, despite the insides being part of the same object, why? Why should I have to go round and manually select the inside of the Os, As, Gs, Ds, Bs, Ps, Qs etc.......particularly when the plane recognises them? Come on Autocad, sort it out, as this on top of the diabolically slow software post-updates is turning into a right pain and wasting my time.

Hi @Anonymous 

Are you looking for the AutoCAD forums?

If you're using Fusion, please share your model or create a screencast to explain what you're talking about here. 

Project seems to be working as expected for me:

Sorry I have been busy working and had to find a work around for this solution, which is more commonly known as an islands problem. Essentially, if I cut the letters into a body, then put a plane through the body, put a sketch on it, then tell select project body, it does not pick up the islands despite the fact they are part of the body. Therefore one has to go and individually select the islands, which is not only very annoying but opens up a source of error. An example file can be accessed at: https://a360.co/2MlT5kB. When one selects project body is should project the whole of the body, rather than leaving islands behind or is there a mysterious setting to deal somewhere within this in the same way some software does for hatching? Is not, then as far as I am concerned it ia bug.

Hi @Anonymous 

Project looks at the silhouette of the body or faces. If the faces are not connected, multiple will have to be selected. Intersect, however, takes a slice from where your plane cuts through the body. It seems like these are both behaving as expected here.
