dimensioning precision of angular plans

[tcoco]

I noticed that when trying to dimension 2 walls not exactly parallel they will not dimension; however if you have 2 walls one is 90.00000 and one is 90.00100 they will dimension but when one is 90.00000 and the other is 90.01000 they will not dimension.

Is there any setting that sets how exact this needs to be? I would like to be able to dimension if 1 wall is 90.1 and another 90.0 or at least be able to dimension if one is 90.00 and the other 90.01

Thank you for your help!!

TAB-Select until you hit a corner. Dimension corner to corner.  

...this what you are trying to do; right?

[tcoco]

that kind of works. I was looking at walls that are off line by an imperceptible amount. I was trying to find a way to set the precision

[barthbradley]

"Set the precision"? I'm not following you.  Are you asking about Snaps (Manage Tab)?  Or are you talking about the Project Units and/or Dimension Rounding?  

[tcoco]

By precision I mean how close to parallel do 2 walls need to be in order for you to be able to run a dimension between them by dimensioning the standard way; not having to use the corner point

Are you having troubles placing walls?  Maybe your Snaps aren't turned on.  Have you checked to make sure "Snaps Off" is unchecked? There's no reason your walls should be askew - unless it is done on purpose.  Frankly, it's harder to make a 91 than it is a 90.  91 takes some determination.

there are a few different wings in the building that are at an odd angle to the wing that is straight up and down, those are the wings i've been having the trouble with

[barthbradley]

Huh? A few wings of the building are at 90.1?

Are you translating a Point Cloud or something? 

[tcoco]

Do you see how some of the wings are at different angles When drawing walls on those wings some end up not being exactly parallel, they end up being off by an imperceptible amount and then revit won't dimension between them

[barthbradley]

I'm sorry, but I'm understanding what the issue is here.  I see building "wings" that are probably intersecting the main building at maybe a 30-45 degree angle. Are you saying the walls in the building wings are not all at precisely 90-degree right angles to each other - that some are 90.1?  Maybe the solution here is to orient the wings orthogonally in the View, so that you can accurately place walls in those wings.   Do you use Scope Boxes?  I would.

Perhaps it is just me but I can perceive the wings oriented at different angles quite clearly from the picture.

Anyhow, even if someone could tell you what the threshold was, it would still be practically useless. Would you try to draw the angle at 90.001 instead of 90.01 just to be able to place a dimension? If the design intent is 90 then model them at 90. So is 91 or 90.01. If the design intent is 90 but the model is not precise then place dimensions to points for documentation purposes.
