Unable to display correct dimensions in Techdraw

Post by papaj03 »

Hi all. I'm new to Freecad and I though this was going to be an easy first project but it's turning out to be way more complicated than I would have expected.

I am unable to get the correct angle dimensions to show in the TechDraw WB. I've searched the form and watched some videos, I've tried changing the view from perspective to orthographic (so I think). I tried linking the angles to the part. Neither have worked. The correct angle as set in the sketch is 60 degrees. This is just one part of a larger project that I've probably spent way too much time on. Also, this is my first post, sorry if I've made a mistake in posting incorrectly. Thanks for any help.

Hi and welcome to the forum!

When you add a view to a TechDraw page it is projected as you have it in 3D view. So it is best to orient 3DView acordingly before adding; usually by choosing one of the main views top, bottom, ...

Thanks but the body is transformed, it is tilted backwards. I have tried extensively to orientate it for a perfect flat view but it's just not possible. So it sounds like you are saying that I will need to undo the transform to get it to set flush with the plane again. Is that the only option?

Orient on vie axis, like you want to have it it the view, then mark a face, you want to have the view direction. Then the view is oriented. Yes, the workflow is not that optimal atm.

you must orient your view according to the plan before projection, for that you can use a macro such as :

Macro_Align_Face_Object_to_View

No, never was. Just click on a face.

Thank you, I just learned something that the wiki was hiding from me (https://wiki.freecad.org/TechDraw_View)

Code: Select all

Optionally rotate the 3D view. The camera direction in the 3D view determines the initial value of the DataDirection property of the View.
