Good evening,
attached a step of two elements (exported as shells) which are not imported correctly (one of them is missing).
The bug is similar to the one already described and Matej solved for 3D models ( Step not being completely imported (PTC Modeling) - Bug Reports - PrePoMax ) but in this case the model has plane elements.
The model was opened with the stable version (2.3.0) and the latest available version (2.3.6).
Thanks for the good work, Prepomax is proving to be a great tool for the new engineers I work with and for the quick and easy analysis.
