Robot Revit Integration question - Structural Axes

tiromos — Fri, 18 Feb 2022 11:11:25 GMT

When I model a steel structure in Robot I make sure that the member lines in Robot coincide with the centroidal axis of the physical steel members.

When this model is exported from Robot to Revit, Revit treats horizontal and vertical members different.

Vertical members (columns): The lines from the robot file, coincide with the centroidal axis of the revit column (Ok).

Horizontal members (beams): The lines from the robot file, coincide with the top of the Revit Beams (Problem).

Is there any way to change this behavior, so that the horizontal lines from the robot file coincide with the axis of the beams in the Revit File?

Regards

Hi @tiromos

Neutral beam axies are transferred 1 to 1 from Robot to Revit as analytical beam model. Revit structural beams families have physical beam position shifted in respect to analytical axis (z justification to section top).

You can change beam family setting in Revit.

Yes, but then there are problems with the connections as it can be seen in the picture below. Is there any way to fix this?

Hi @tiromos

In Robot you do not define workshop model (while Revit connection templates are designed for default Revit families) so I do not think there is good solution for that.

If you want to convert exported Robot model to workshop model with connections I can suggest the following

- modify Robot model in the way that beam axes represent top beams positions

- start modeling in Revit (creating your physical mode) then export analytical model to Robot for calculations

For steel structure workshop drawing I would suggest Advance Steel (software created for steel workshop drawing generation). Model can be exported to Advance Steel from Robot as well.

Ok, thank you
