Getting dimensions from a model

[juliangall]

I am new to AutoCAD and have been sent a 3D architectural model. I need to find the dimensions of some beams. The measure tool seems only to measure from point to point, and I need to measure from one side (or edge) of the beam to the other. The beams are not along the axes and the ends are not at right angles so there are no points that correspond to the height and width.

In Sketchup, I can easily measure from one line to any parallel line. How can I do this in AutoCAD?

Thanks,

Julian

I’m not aware of such built-in feature in AutoCAD to measure from edge to edge on 3D solids.
May try to measure from an arbitrary point from first item to a perpendicular to the second one - check Osnap mode for this. To overide temporary current setting, just press simultaneously <Shift> and right-click on mouse.

Midpoint to perpendicular?

[juliangall]

That's just what I needed. Thanks very much Mircea.

If the arbitrary point is not selected using one of the Osnap overrides then how do you know what you're picking as that first point?

[MSasu]

You are right, I should have given a much detailed explanation on this. I have implied that an arbitrary point selection requires usage of Nearest mode, but other may not think the same. Sorry for confusion and thank you for correction.

It is not a matter of me correcting you. I just want to make sure, as I think you do too, that the OP is picking somewhere on the correct beam or some portion of it otherwise the distance he gets may be incorrect.

Welcome to the forum.
In 2012 and 2013 you have available 3D Object snaps.

I'm guessing you meant to say it is NOT a matter of........

You are correct. I did forget the word "not". Jeez, I can't type today.
