Cant Click On Surfaces

[jojo]

Hi , I am new to PreProMax and I was following FEAnalyst tutorial 5 for thin walled pressure vessel on youtube. I cant seem to click on surfaces to apply pressure loads. (I have imported Step file from onshape,).

Which version of PrePoMax are you using and what are the selection settings (in that small Set selection window) ? Can you share a screenshot or a gif showing what happens ?

I am using version 2.0.0 . I am selecting surfaces edges and vertices.

Try zooming in and out or moving the object. Try some other geometry (maybe solid) if it works. What are the dimensions of the object and are the dimensions in tact with the bottom scale bar? At the end try using developer version 2.0.4.

I have tried zooming in and out and moving the object but that doesn’t work. The scale looks OK. I will try your other suggestions and see if that works. Thanks

I have tried the suggestions but it still doesn’t work. See screenshot with solid elements. I can select the surface in red. But cant select the clouded surface. Any further suggestions would be appreciated.

Thanks
