I finally started to gather all the custom nodes I have been
creating for the creation of rebar objects in Revit using
Dynamo. Besides using the
Dynamo for Rebar package from CORE Studio, I
also created some small productivity tools that can help you
driving your rebar design. The package for Dynamo that has been
published is called BIM4Struc.Rebar.
At this moment it consists of a limited number of custom nodes,
but there will be added more and more, as AU gets nearer.
The ones that exist now in the package as a starter:
Rebar.GetHost returns the Revit ID of the host
that contains the rebar object. In case that the rebar is not
hosted, then it will be returned in the NonHostedRebar.
Rebar.GetCenterlineCurve is a node that
returns the sketch geometry of a rebar, which is in fact the
centerline. This is very handy when distributing existing
complex rebars along 3D curves (using the Dynamo for Rebar
Rebar.GetProperties is a node that extracts
all necessary rebar properties from a selected rebar in Revit.
These properties can be used in combination with the
Dynamo for Rebar creation nodes to copy
existing rebar for instance.
This helped me to make a quite short script to build the rebar
in this double curved deck.
There will be explained more on this in future blog posts !
