Moving Walls

Revit
1

I was able to create wall geometry from Dynamo. I would like to in the future move it. I have in the past been able to move elements using the Element.SetLocation node, however, I can’t get it to work on walls. Does someone have a simple way to move walls instead of creating new walls?

Hi Danny,
Element.Set Location works for walls also.

Kulkul,
It might be how I’ve got it setup. I’m sending in a curve and then a list of elements. Would you mind letting me see the .dyn setup?

Thank you.

I think Element.SetLocation is looking for a point, not a curve.

You need to send points not curves.

Kulkul & Greg, Thank you.

where is Element.Location ?

I can not find it.!!!:confounded:

@psynan,
it’s in Clockwork Package

Sorry for dredging up an old topic but I can’t find another one.

What am I doing wrong?

Points has no output, curveEndpoints has an output but it doesn’t move the element (wall).

Oh, feeding it curves seems to work .

I was struggling with moving parallel walls with hosted doors. element transform utility does it and chatgbt 01 sorted the rest for figuring out the vector for movement from the location curve and rotation. Although unsure the rotation it implemented was necessary
