Missing Lines

I tried to create an assembly drawing using drawing processes, but the beam is missing, it shows me only the dimension and the name

Could you open the property Dialog and have a look if the visible lines are set to on? I could not have a look for the DWG, but often the model object in the model have not correct cuttings?

I open the model and it seems to work for me but the Mainpartnumber is not shown in the Title.

After renumbering your model it works with the title

I checked the properties, and the visible lines are on. Also, I opened the file in another computer but still the same issue

I find similar problem. Specially after changing anything in model. Parts dissapear from drawing. Only name and centerline are shown. I can't afford to renumber model every time I change one element after all drawings are generated. Sometimes individual parts dissapear from assembly drawings.
