Hi everybody,

I have a strange bug with 2d sketches recently. When I have a hole with a diameter lower than 8 mm I don’t have the center mark but a single dot on the outline of the hole.

 ![hole center mark](https://us1.discourse-cdn.com/flex002/uploads/shapr3d/original/3X/b/a/ba0dbcfaa9ccce0268b54faeaf7a1c8d8ef5e089.jpeg)

The holes are on the side of a tube with a Ø40/34mm diameter. Does this strange behavior occure because the holes are not on a flat plane? I never noticed anything like that before.

Thanks for your ideas how to fix, or work around it.

(working on an Intel iMac with shapr Version 5.490.0)

Thanks

Matthias

Hey @msx3000,  
Could you please share your design (in .shapr format) to better understand the issue?  
TIA

Hi H\_Daniel,

I prepared a version with just the 2 tubes in it. The behavior is the same, I can’t get a center mark with the holes on the tube.

Thanks for looking into it 😄

Thank you for the design and for the report, it was very useful. The issue is created, we’ll investigate the root cause and prioritise it soon.
