Join polysurfaces

this is a basic question regarding joining poly surfaces, could you please explain why this object cannot be joined into one poly-surface. thank you

because you are trying to join 3 edges at once creating a nonmanifold object wich is not good.

thank you for you reply, any suggestions to create the same shape without having to join 3 edges?

Hi,

As @DiegoKrause said you have nonmanifold object and if you move & try to join you will get these issues.

Cheers,

what’s the objetive? you can group those objects if you want to move them together

hmm, wouldn’t that be a problem in case of 3D printing?

DiegoKrause · July 10, 2020, 7:36am

yes but having only that is not clear what you want or why you need that geometry in that way

so the shape is needed to hold a piece between two surfaces, as shown in the sketch.

then give it some thickness

Thank you
