According to the title, I would stick here to the error and open a new question for cylinder enlarging, a new question for yellow box and a new question for not displayed walls (well, the last two may be joined as they really are related. But e.g. the error has nothing to do with yellow box etc.) Also note that the attached script should be a MWE ([1], point 3), so e.g. for not displayed walls, cylinders and most of the code is irrelevant and a MWE for the not displayed walls should focus only on walls. (this way, often you can find the answer yourself). > the script points out a ValueError: cannot convert float Nan to integer when you get en error, please post **complete** error message ([1], point 2). Usually there is also the specific line which is very useful. > when I start running my script Also please provide information about your OS and Yade version ([1], point 4) and how you run it. I used recent yadedaily (20220504-6539~3497d6b~jammy1), run 100 iterations of your script without any error.

Additionally, the script points out a ValueError: cannot convert float Nan to integer After I create the walls via aabbWalls(), only 3 walls are shown in the 3D view, why is it not showing all 6 walls? Finally, I checked my script and there is no code to create the yellow box shown in the 3D view... So, why the 3D view show this yellow Box?
