Level Dimension Tool on Walls

Anonymous — Mon, 22 May 2023 21:53:29 GMT

i am trying to place elevation dimensions in my Plans for several short walls around my building but the elevation object wont read the height of the wall but of the closest slab.
If i have a 1 meter wall, the elevation dimension will be 0.00 instead of 1.
Whats going on? some hidden option perhaps?

Yes, this is how it works. The Level Dimension can be associated only to Slabs, Roofs, Shells and Meshes using the Gravity feature. It cannot be associated to Walls or Columns so it cannot associatively display their top height.

Isn't there a label tool (as in AUT Version) for defining the upper and the lower egdes of an element. We use it mostly for beams, and I suppose it should work with a wall also.

Well, that is a different thing from what the OP was asking about.
But, yes, it is possible to use an Autotext Label which displays the Height of a Wall, so it would effectively return the height of the Wall Top.
It would also be possible to create an expression-base Property, which would return the Height of the Wall's Home Story + Wall Height to display the top of the Wall from the Project Origin.
This could also be combined with a custom graphical Label, where one would draw the graphics of a Level Dimension, plus place a Text Block displaying this Property, and save the whole thing as a custom Label. That could look just like a normal Level Dimension, but displaying the height value of Wall Tops.

ok i created the custom property and expression and it works with the label tool.
Can you elaborate on that last part? i need to draw the elevation graphics myself ? with lines and fills and convert it somehow to a label object?

Yes you can create your own labels from text/autotext, lines and fills.
This may help explain the process.
