Then I want to cut angles with sketches. I got the following result with Length "through all".

Please don't zip FreeCAD files here, they are already zipped. Will have a look at the file.

The problem is in the Thickness command, which is known to be one of the most problematic commands in FreeCAD. The issue comes directly from the third party geometric kernel and there is nothing the FreeCAD developers can do about it.

Part>CheckGeometry shows the issues.

Here you mean that when the thickness is suppressed, the problem could be solved ? But I got a result with thickness and a taper angle = 0.

No wonder, with tape angle=0 there are not complicated faces and CheckGeometry shows no errors.
