Summary0001211: ... cannot be written to BRep file ... Error on saving a model
DescriptionI have classed this as minor, not requiring fixing, because I only noticed it while running FreeCAD on Windows XP. However, I am logging it as a bug in case anybody else tries to save a complex model using an old computer with slow disc drives.

The symptoms are that on re-loading the file, some (or all) the shapes fail to be rendered. In addition, if the "report window" is open, and logging of errors enabled a

      "... cannot be written to BRep file...

messages appears on save.

As workaround, each time an affected file is re-loaded, make a trivial edit to each of the affected sketches.
Additional InformationThe symptoms were found using FreeCAD version 0.13 (stable), and re-produced using Version 0.14 Revision number 2370(Git)on two Windows XP machines. They did not appear using a modern laptop.

To reproduce, create a sketch containing a circle surrounded by a perimeter composed of a dozen arcs, and closed by a straight line. Pad the sketch and chamfer the resulting hole and perimeter. Create a second sketch with only a rectangle, and cut this out of the first. View the "report window", and save the model. If no error message occurs, save the model twice by pressing Ctrl+C twice in quick succession, or increase the model complexity by copying and pasting parts.

I'll close this because it seems to me that no action is required. Please reopen if needed.

I guess this should stay open. From time to time I got this error also on Windows but could never reproduce it reliably. I'll re-check it ones I encounter the problem...

I haven't observed this issue for a couple of years any more.
