Mask Regions with '0mm' dimension ?

I'm using a couple of masked regions to form symbol linework (so that it obscures background and shadows) in section.


In my screen family, I have a masked region that in theory could end up having a 0mm length - that obviously throws out errors.


The following screen grab shows the regions (at screen soffits) that are set to lock to the frame face and external wall face. Trouble is I have an instance parameter to allow the screen to fill the whole wall thickness (which also then toggles on architraves). This results in the 0mm. I have therefore done a slight 2mm overlap to avoid the issue, but this leaves a residual ovelap in the linework that looks ugly.


Setting the masked region to simply not display doesn't avoid the problem, Revit still 'sees' the errant 0mm.


Is there a way of having this masked region working in both options (ie when needed - locked to ref planes) and then not producing the error when the frame and wall are coplanar ?

in situations where i run into the potential for 0 dims, i do one of 2 things:
a) rather than use 2 reference planes that could overlap, i dimension from one, and use a parameter formula and visibility that is more or less, if =0 make it 5 and not visible,
b) offset the line a stupidly tiny amount from the reference plane (assuming they can overlap, but can not cross) so that my linework gets a 1/256" wider, but no one will ever notice, and it won't mess up dimensioning.

Thanks for the pointers!


Got it working now - used formulas as suggested to calculate an offset (and not locked to the frame face) - much cleaner result.


I now have the internal glazed screen with instance options to:


Center to wall

Flush to Extenal Face (with architraves added)

Frame full width of wall (with architraves added to both sides)




Many thanks for your help,
