RiR - AddBeam.ByCurve


thanks for the awesome work.
I’m having problems with AddBeam.ByCurve component for Revit.
As soon as I change the geometry (with slider) i get an error:

However, as soon as i disconnect the input geometry, and reconnect, the error is gone.


Hey @shabicedin
Welcome to the community. Would you mind translating the first two warnings?

Thanks :slight_smile:

Hi @eirannejad,

here the error translation:

  1. Object reference not set to an instance of an object
  2. Position for cutting plains leads to inclined pillar without geometry

I also found a bit older but apparently not cleared thread, with the same problem:


I had same problem, today I have downloaded the source project and recompiled
linking the revit 2020 libraries, then got the new rhino wip and it seems that the problem
is gone



thanks for your answer. I was hoping for a fix.
I think it will be difficult to get the corporate IT to compile source code…
+every time a new Version is out.
