Sketchup offset corner Loop irregularity
-
Hi Everyone.
I have been using Sketchup Make for some time and I have recently downloaded a trial of Sketchup Pro, on Mac.
I have noticed that there seems to be a bit of an anomaly between the 2 with offsetting. The problem has been happening across a lot of projects, I regularly get different geometry from tutorials.
I have a simple example which highlights the problem. I copied the same shape from Pro to Make, its a 32s arc split in half, finished into a quarter circle shape.
On Make no problem offsetting.
On Pro it creates extra corner loops.
(Pictures attached)
Could someone let me know whether this is a setting, or something I may be doing, or potentially a bug.
I would be grateful for any help. Thank you in advance.

I don't have any problem offsetting a simple pie shape in 2019.2.

It looks like you have a short edge segment in the curve in your 2019 version that isn't there in the other one. How did you create that?

Thank you for picking this up Dave.
I did:
150cm line on red
75cm line from the center on green
arc from ends of 150cm line pulled out to 75cm - 32 segments
delete half the arc
offsetLoops start to appear after around 6.5cm on pro. The same process on Make and loops never appear.
As far as I can see the first segment is in the same place on both files, new files attached.

Upload the actual SKP file that gives you problems.

What Pro version are you trialing? When I open the file called Corner Error it gives the message that it was created in SU2016.

When I run Offset on your example on the left, it works just fine.

When I open your "correct" file, I get this.

And Offset works fine there, too.

You are exactly right.
I have downloaded the new version and all is fine. It seems it was a bug with the older version.
Thank you for your efforts.

Just for the record, there were indeed bugs in the offset tool in previous versions of SketchUp. They are much improved in SketchUp 2019.
