Snapping in Elevation view


Recommended Posts

I'm attempting to dimension the height of a exposed ceiling beam in a elevation view. (Roof beam is perpendicular to the view.) I can't for the life of me get anything to snap to it. Tried the elevation height marker, all the dimensions, drawing a line, etc. Surely there is a way to do this, right? In the previous CAD programs I have used, this is a 5 second task. These are the types of things that waste so much time....

 

Sorry for the rant. It feels like I design for 10% of the time, and google how to do things 90% of the time.

I watched a view videos this morning, and the instructor did a similar thing. She used point to point, and zoomed it to get it "close". Surely that's not the way? That gives some unknown amount of error, and the bigger issue is that if you change the beam height, the dimension doesn't change with it later.

To get otherwise inaccessible snaps, I use CAD Detail From View.  Copy a line from that newly created CAD Detail and then Paste Hold Position back into your Elevation View.

I tried that, but I could not snap the line to the top of the beam. I can get it "close" but not exact.

You're probably doing something wrong then.  If you can SEE the top of your beam and if that line is drawn in the CAD Detail From View, you should surely be able to snap to the line in your CAD Detail From View.  Either copy that line directly, or snap another CAD object to it and then Cut/Copy and PASTE HOLD POSITION (Edit>Paste>Paste Hold Position or Control+Alt+V) your snap reference line back into your elevation view.

 I get what you're saying to copy and paste the top of the beam back into the elevation. But, if I make any changes, I have to redo the whole elevation. It's a quite a work around, but I guess that gets me limping for now. Thanks for the help.

This can be done without going the cad detail route.

You can dimension to cross section lines.

Unlock the Cross Section Lines layer and make it red and thick so that you can see them.

Use the Backclipped Cross Section camera.

The trick is to locate the camera so that it is within the beam (you can do this by temporarily making the beam really thick so that the camera is inside the beam, or, locating the camera inside the beam) - this can be a temporary location so as just to get the dimension to snap to the  beam - you can then move the camera and the dimensions will stay.

If you use the End To End dimension, it will place point markers to locate the dimension points.

So, if you want to move the beam, make sure you select the marker and the beam and the dimension will move and update as you move the beam.

Not perfect, but does work and is a lot quicker to do than it sounds.

This pic shows a roof beam parallel to the camera and another perpendicular to the camera.

The one parallel to the camera doesn't need any attention because the camera is within the beam.

I don't see how this is any faster than simply creating a quick CAD Detail From View.  If you have no snaps to start with it means you weren't cutting the object with your camera meaning you would be required to reposition a camera at least twice and you would still be dimensioning to a dumb CAD object (i.e. there would be no functional difference from stealing snaps from the CAD Detail). For the camera cutting the beam you would already have snaps and we wouldn't be having the conversation in the first place.

Some of us just don't want to use cad from view b/c it's not updatable  I never use any cad within the plan. For me only details are cad.

I wasn't suggesting using the CAD Detail itslef.  Only stealing a snap from the CAD Detail in the form of a line or point.  If you dimension to a Cross Section Line you're doing the exact same thing.  Cross Section Lines are nothing more than a temporary CAD objects and don't remain tied to the model either.  Glenn knows this which is why is he said...

Both methods require dimensioning to CAD.  The question is this.... Is it faster to created a CAD Detail From View and then copy/paste from there or is it faster to move your camera twice. 

 

P.S.  There are also TONS of situations where cross section lines aren't even going to be an option and where a CAD Detail From View is the only viable method for accurate snap points.
