🐞 Description of the bug
With the following model, if you try combining each of the screws, the screw will disappear.
📝 Steps to reproduce
scfile = Path("D:\AnsysDev\pyansys-geometry\tests\integration\files", "Basic_Combine_2014.0.scdocx") #dsco")
design = modeler.open_file(file_path=scfile)
bottom_plate = design.components[1].bodies[0]
screws_1 = design.components[4].components[0].bodies[0]
screws_2 = design.components[4].components[1].bodies[0]
screws_3 = design.components[4].components[2].bodies[0]
screws_4 = design.components[4].components[3].bodies[0]
screws_5 = design.components[4].components[4].bodies[0]
screws_6 = design.components[4].components[5].bodies[0]
screws_7 = design.components[4].components[6].bodies[0]
screws_8 = design.components[4].components[7].bodies[0]
screws_9 = design.components[4].components[8].bodies[0]
screws = [
screws_1,
screws_2,
screws_3,
screws_4,
screws_5,
screws_6,
screws_7,
screws_8,
screws_9,
]
design.plot()
for screw in screws:
bottom_plate.unite(screw)
design._update_design_inplace()
design.plot()
design._update_design_inplace()
design.plot()
