In the attached file, the cone placed at the origin was generated by extruding a circle to a point and with no end cap selected.

Using the Shell tool to thicken it up a bit, gives a rough result and I wonder if this can be tweaked.

The other cone was made from a revolved line and the surface thickened in the same way as before, but this time, has turned out as expected.





Thanks.

I've got this updated for the next v3 beta - in the next beta when using Extrude to point where the base curve is a circle or arc shape, it will make an analytic cone surface out of the result and that will help this case to offset properly.

Thanks for reporting the problem,

Ha that sounds cool..

Peace,

There seems to be something odd happening when I edit the size of an arc if it lies directly on top of a circle.
Please take a look at the video to see what I mean.

There's a feature in the resizer where if you're resizing a line or an arc, it scans through all the other objects to see if there are other existing curves that touch the current one at an endpoint, and if they do it uses that endpoint as the scale origin.

That enables behavior like this - when you edit this radius of this arc here:




The edited arc gets scaled like this so that it's still connected to the adjacent line:




The same thing is kicking in for your case with a circle - a circle also has a start and end point to it even though you don't normally see it, and if the arc being sized touches that point at one of its ends it will get anchored to it.

I'll tune this mechanism up so that it will skip closed curves when it's looking for any other touching curves since it's pretty weird behavior in that case.

Thanks for reporting the problem,

Thanks Michael.

And thanks also for providing this feature - it's great being able to edit an arc in this way, I usually have to erase and redraw in such cases.
