Cannot create a projection

[napwodz]

Hi.

When trying to create a drawing of a step model, I cannot create a set of projections - I get an error:

10:29:10 pyException: Traceback (most recent call last): File "", line 1, in <class 'Base.FreeCADError'>: vector::_M_range_check: __n (which is 18446744073709551615) >= this->size() (which is 3)

Whatever fil I try to work on, I get the same error. A ProjGroup is created, but when I double-click on it to edit, I get Segfault and the following message:

Program received signal SIGSEGV, Segmentation fault.

@napwodz is this still an issue with the current weekly build?

[napwodz]

Sorry for late reply.

The problem lied in negative value of the "LineStandard" parameter and AFAIK it has been solved with: https://github.com/FreeCAD/FreeCAD/commit/6337b454e1

Thanks!
