Hello!

I have some geometries hard to handle but looks very simple.

One of these Offset is not working in this case. geometry doest union. after union fillet (straight) does not work with 0.6 and 0.1 values

Hi Andras - could you please explain a little more about what exact offset you're trying to do?

I loaded your file and tried offsetting all the individual surfaces by 1 unit and they all seemed to generate an offset.

Then I tried joining them together into a solid (using Edit > Join command) and that also seemed to offset.

One thing that may be causing a problem is that there seems to be an extra degenerate surface in your model - I noticed when I did an area select that the selection indicator said "7 Surfaces" were selected, but there are only 6 big surfaces that seem to be present. If you select the 6 main surfaces by clicking on them:



And then delete those, you'll see the 7th surface is this little fragment that looks like a line here:



So probably that little degenerate surface (it may be a surface that has all of its area trimmed away from it so it's more like a line instead of a surface) is causing some problems?

Hi Andras, also I see now that trying to join only the 6 big pieces together does not give a solid - doing that and then selecting naked edges led me to this small irregularity in 2 corners of the shape:








There seems to be a tiny micro edge in those areas with a length of only 0.003 units - that's almost certainly what is interfering with filleting.

It looks like you may be able to fix that by selecting the 6 main pieces and using the Merge command:

That should merge the micro edge with its much longer neighbor so it's all one single long edge.

I've attached a tuned up 3DM file where I did that - this one should probably behave better for you now.

Hi Michael!

Thanks for your answer. my model looks messy , sorry next time I should check before send I gonna check it again, I set 0.6 value, anyway. thanks again.
