Cant draw arc

[nekajcasa]

I cannot draw an arc. PyMAPDL only connects points with a straight line, although I am in the cylindrical coordinate system.

Hi @nekajcasa
PyMAPDL is actually meshing the line and plotting the mesh as a VTK object via PyVista. And for the arc it is meshing with a single linear line/beam element so it looks straight. If you use the following:

mapdl.view(1, 1, 1, 1)
mapdl.lplot(vtk=False)

You will get a plot (as a png file) from MAPDL showing that the line is indeed a arc. Perhaps the PyMAPDL developers (@germa89 et al) can implement a 'quality' control on lplot as aplot and vplot have....?

p.s. can I ask why you are using a lot of "run" commands instead of just the PyMAPDL version of the commands?

Thanks for the reply, that was the problem. After connecting lines into the area, it renders correctly in vtk as well.

I usually use python commands, but here I tried all the options and it just happened that this was a case that I sheared...
