Hi quick question ,
Im battling with dimension.ByFaces again 
.
The dimension is created. Image 01, however gets deleted in order to run image 02
PS If i manually select by faces i have no issues however obviously trying to avoid this approach.
Is there anything obvious I’m missing , thanks in advance.
Cheers KS
Hi @Kai …not sure have you tried pull your line on viewplane…
After pulling onto the plane , use something like this to convert into a line again: Line.ByBestFitThroughPoints(crv.PointAtParameter(0..1));
Are you sure the two surfaces are parallel? Remember Dynamo won’t let you do anything you can’t do in Revit.
Hi @jacob.small yes I believe the two surfaces are parallel ie if I use pick face’s directly and feed them into the reference surface it works.
Only thing I’ve done here was filtering them down from the element faces nodes until I got the two outside ones , maybe the way I obtain it could be an issue?
I’ll take a full screen shot when I’m back in front of the cpu.

Hi @Kai yeah guess the ootb node need revit surfaces, for get reference…probably it works if you insert a revit surface with import instince and use that surface…have you tried with dimension from reference node or genius loci, as i almost always use for that
Hi @sovitek, @jacob.small , ill have a play today. I believe i can get it with reference planes but was hoping to use surfaces if possible, even if i grab the DB reference from the surface i still have no luck (refer image 02).
Attached image is how i filtered originally.

Hi @sovitek 
maybe that is way easier will just need to rename my ReferenceNames across other families.
