2 years ago Hi @herttim The volumes were plotted, but the working coordinate system was not changed so the VGEN resulted in the volumes being created along a straight path. Zoomed out the volumes appear so small you can't see them. And zoomed in they are not on the screen. In the input file the coordinate system needs to be changed, and the VGEN command changed so that the location increments are along DY which is local theta direction. Additionally the local coordinate system is not defined such that the axis is aligned as you expect, so the volumes are not in the correct plane.
Resulting volumes from changes:

Before submitting the issue
Description of the bug
I want to create a rotationally symmetric model of the rollers about the x-axis (see picture). Therefore, I´ve implemented a new local COS to transform the whole geometry. I have done this, because a rotation arround the x-axis is not directly possible. While plotting the model, PyAPDL doesn´t show the geometry anymore.
Steps To Reproduce
`from ansys.mapdl.core import launch_mapdl
mapdl = launch_mapdl()
mapdl.prep7() mapdl.units("SI") # SI - International system (m, kg, s, K).
define a SOLID185 element type for ET1
mapdl.et(1, "SOLID185")
define material ET1 (nominal still in SI)
mapdl.mp("EX", 1, 210e9) # Elastic moduli in Pa (kg/(m*s**2)) mapdl.mp("DENS", 1, 7800) # Density in kg/m3 mapdl.mp("NUXY", 1, 0.3) # Poisson's Ratio
