How do I insert dimensions in a pyramid correctly?

frank_ringfrank_ring Member Posts: 21
Hello,

I am trying to make a simple example drawing with this part (plywood, 18 mm) which has a slope on the pyramid of 15°.
How can I correctly measure the plane A with the cutting plane B in this drawing? Essential for manufacturing. In reality this is not 90°!
Thanks for your help!

    You're seeing inaccurate measurements in your drawings because you're parts are not aligned with the default views (Top, Left, Front, etc...).  What you can do is go back to the part studio and create "named views" where each part is aligned appropriately for your drawing. You should only need one per part.

    Then, you can insert these named views into your drawing and create projected views from them.

    Hi @frank_ring

    try normal (shortcut  key ‘n’). After selecting surface.  Or for more control add a mate connector and normal to the mate connector.   With the creation options including move/rotation allows precise orientation of mate connectors.  They act as extra coordinate systems.

    @frank_ring, you might also explore "auxiliary views".  That can be created directly in the drawing.

    Thank you for your feedback,
    the Named views work well, only the alignment in the Part Studio is not possible precisely, in my case a horizontal alignment of the 15° angled plate.
    Is there a way to set the view exactly to one surface?

    Ok, thank you very much! That was helpful, now it works.
    In the meantime I found this useful instructions.
