Problems with Draw Style on Arcs

[elsordo]

I have a strange problem. I have a model, called house.fcstd, that contains two arcs in addition to other geometry. The arcs disappear when I set the Draw Style Property to anything other than "Solid". In the same model, I created a Line object and had no problems setting the Draw Style property to dashed.

This seems to be related to the configuration of data in my model. I discovered this when I created another model, called TestArc.fcstd, that contains a single arc object. With this one, I do not have any problems setting the Draw Style property to Dashed.

So what is wrong with the house.fcstd model.

My freecad installation information is

I have no problem with the house model either...

Maybe something wrong with your graphic drivers? Everything is up to date?

Indeed, the problem is with my platform. I tested the behavior on a Windows box and a different Ubuntu box and found that the Draw Style worked correctly.

I tried updating the open-source drivers but the problem persisted which is not surprising given that the Mobo/Processor pair dates back to 2011.

Thanks for the help.
