Default Bevel a vector on top of inconsistent shape?

Hi all,

I have a fairly complex design I am trying to make efficient. I am usually pretty good at the whole trial and error thing, but this one has me scratching my head. I'll try to explain it the best I can:

I have a 3D shape that I am trying to stack a simple vector-based shape on top of that needs to have a beveled edge. I basically need a 60deg bit to follow the simple vector for the bevel, but also change how deep it cuts based on the shape underneath it to create a seamless transition between the simple shape and the 3D shape. I have already tried just adding it to my 3D model and machining it that way, but I really don't want to go this route because the finish quality left alot to be desired and on top of that 3D machining is quite the time-sink. Is there something I may be missing in the software that will do this? The 3D shape is not an even thickness.

I realize how complicated this would be for the software, but I am constantly surprised by what it can do and figured I would ask before changing up my design completely.

Thanks!

If I understand you correctly...if not sorry.
You should be able to project your profile (60 deg bit) on to the 3d object (it is a button at the bottom of the profile toolpath tab.

Thank you for the reply. The issue with that is that it cuts into the 3D model by the amount set in the cut depth. I need my cut depth to change with the model contours that way it never actually cuts into the model, but still bevels the edge of the shape on top. It is way simpler said than done, but I pretty much need a profile toolpath with a varying cut depth based on the 3D model the vector is sitting on.

take the vector you need to cut around and make a flat model using that as the outline, added to your original 3D model. This will just add a constant thickness to your original model.

Then project your profile cut onto that. You may want to offset your vector just a little to make it larger before creating a flat model, so that you aren't projecting your profile cut onto the edge of the new model.

A couple of other ways to approach it are:

Offset the 3d model by the thickness that you want and then cut the profile projected onto the offset model. Place the offset model on a separate layer to make it easy to shut it off while toolpathing the original model.

Project the profile onto the original model and use a cut depth of 0.00. You will have to compute the appropriate offset for the profile vectors using this method.

If you need it to tapper down, how about the fluting option? May have to break the vector but that would be easy enoug.

Thanks all. Will try these - the 0 cut depth projecting with calculating the v bit offset sounds like it may work the best. I'll try the others if not!
