I cannot reproduce this one. [Issue2095.pdf](https://github.com/user-attachments/files/19618652/Issue2095.pdf)

@Questions2000 Clearly, you are the expert here. Is this appimage only? or you can reproduce this from a local debug build, hopefully, running as "librecad -d6"

@sand1024 I feel we should add a boolean to indicate a 2 pi length of the arc. If boolean is on, and the angular length is close to 2 pi,...

@sand1024 For arc, we should keep angular length an invariant in all operations, including painter. Let me also review the cut algorithm here. For painter, We may simply do, double...

@sand1024, Let's commit your fix for 2.2.1. In 2.2.2, we are going to make the angular length an invariant.

For 2.2.1, let's try a safe fix: if the start/end points are coincident, assume the angular length is 360 degrees. For 2.2.2, I feel we should make arc angular length...

So far, no issue reported from 2.2.2, we are going to backport the new alignment algorithms to 2.2.1_rc

Could you upload the dxf with this issue? This is an issue during hatch processing.

This issue was caused by some border calculation optimization: unless being forced, the entityContainer won't calculate the bounding boxes for invisible entities. This causes some zero sized bounding boxes during...

@Jim-2249 K or kill should terminate the command and add the spline here. I will have a look and include the fix in the next release 2.2.1.2
