Reference line - labeled angular dimension

[eddy.lermytte]

Hello
In a door family I locked the symbolic plan swing lines on a reference line which is labeled by an angular dimension. Fig 1.
Everything works fine for angles between 0 and 179°.
Once the input in the family types is > 180° (for examples 225°) the symbolic door swing stops at exact 180° less although the reference lines is positioned right. Fig 2.
At 180° "constrains are not satisfied" but I just can't figure out whats going wrong.
Any idea ?

Is this odd ?
I can't figure out why the arched symbolic line follows the ref. line only when the labeled dimension is less than 180°. Attachment 1.
I think this causes the problem I mentioned above.

Hi Eddy, the problem lies in the way Revit figures out an angular dimension. If you delete the arc and the line, and keeping only the ref. line, you will see that you will still have problems. When I try a similar example of your second figure I get a slightly different outcome. When I enter 225 as an angle, the ref. line rotates to the right angle, but the dimension switches sides, it ends up showing 135 deg. from the top side, instead of 225 deg from the bottom side.

I think the main question is: can live with a door that swings less than 180 degrees? If you don't want ever an user error, you can include a formula that only enters an integer between 1 and 179 (see conditional formulas if you are not familiar with it)

I hope your satisfied with my help. Take care,

By the way, try putting a negative number instead of more than 180....i.e. try -135....the problem becomes a different one:?:

Would you have doors that open more than 180? Do you have doors opening around corners?

Luigi - Scott > thanks for reply.
I can live with doors that swings less than 180° and I know how to constrain them. However a lot of things turn around more than 180°. In that case it seems that a stupid workaround I used in another family will do the job.

PS:
Scott
the rfa file is not a door :) > what about this high tech device ?

Just joking, Eddy

[Scott D Davis]

Nice hinges! yes, I can see where you would need it in that case. I thought you were specifically trying to do it in a door family, and didn't open the RFA you attached!8)

Does that mean that if you wanted for instance to create a clock face with hands that would be driven parametrically you could not do it in Revit? I would be surprised if this was the case.

You can have angles greater than 180º! I use this for north pointers which are embedded in the titleblock families. I think the problem your experiencing is at horizontal and vertical levels ie: 180,90,270,360º revit automatically constrains items to planes.

I've found that sometimes when these don't work in the families they actually work fine in the project. Have you tested 180º in a project?

[eddy.lermytte]

Mr Spot.
I did a try out > same results as in the family editor.

I am surprised to this can only be solved by means of a workaround.

I have a door which can have greater swings but the panel is done via a nested family...

[eddy.lermytte]

Mr. Spot > I'll give it a try that way.
I walk around the 180° constrain by labeling the opening-angle twice.
