I wanted to show an example of something that would help solve the fillet/chamfer boundary issue but then ran into one myself.

The basic premise is to build your own radius fillet or chamfer, and in a simplistic sense I was about to do this when I ran into a trim issue. Using a project curve to remove surface material, the results are odd where it won't completely trim the surfaces I want removed 'inside' the projected curve.

I didn't try this as a surface, considering instead a trim curve is cleaner methodology:

Hi Jason,

I found in this situation it's not necessary to project the trimming curve, if you do your trimming just with the circle that you have there above the surfaces it will trim as expected.
Another thing here, you will get about 3 results in the following methods, if you pick the whole body and do a trim with that curve it will trim every surface in it's path, then there is where you can pick just the surfaces you want to trim (that's pick the solid then second pick to choose the surfaces) which will trim just those surfaces , but you will find that the hole is still connected to the trimmed surfaces so you'll have to separate that region, and lastly as you mentioned you can do it as individual surfaces by 'separate', do all your operations, trim, fillet etc then do a join at the end to form your solid.

My theory on why that projected curve won't do the trimming is if you turn on the control points on that curve you can see the number of points involved in making that curve so MoI has to do that extra calculating on all those points and can't handle it, as I said just my thought, I may be corrected.

Cheers

ive seen that model before somewhere ;) good to see your posting and getting into moi mate

Danny,

Unfortunately I was in the middle of trying to show an example of something but got stalled by the trim.

I can do this trimming in other apps, so I do want to note the issue here. This type of modeling isn't exactly out of the ordinary, however for a chamfer I do realize I was going extreme but like I said I was trying to go somewhere with it.. hehe.

Thanks for the reply.

Good responses here!

DD: Cheers ;) This model is getting pimped :D

Trying to follow what u guys are saying here..

So the best route for this is create the chamfered area detached and then rejoin to the main surface.. I think that can be a work around.

Been really busy, going to have a bash at this tomorrow evening.

Thanks for the input.
