I’m trying to get the Dimension.ByElements node to generate a simple string of dimensions in a section view. But I just can’t seem to figure out why Dynamo keeps throwing an error on that node.
Here’s the error:
“Warning: One or more of the input types are not matching. Couldn’t find a version of ByElements that takes arguments of type (Revit.Elements.Views.SectionView,__array,__array,string,string)”
Any ideas on what I am doing wrong?
Connect elements list to “Reference Elements”. Currently your connecting Reference planes.
Kulkul,
Guess I’m more of a newb than I thought. What are Reference Elements exactly?
I did a search thru the Dynamo Dictionary as well as a Google search, but I didn’t come up with anything about Reference Elements.
Thanks
@josephprouty Here is a simple workflow showing the process.
Still got the same error when I changed my graph to this,
When I did it the simple way, I was able to get it to complete successfully, however no dimensions actually showed up in Revit. Which I thought was really odd, no?
Could you drop or share the link to your rvt file on google drive /dropbox / wetransfer.
Here you go…
Thanks again for your help Kulkul.
Kulkul,
So I need to use Gridlines in-order for it to work correctly, is that what I was missing?
Kulkul,
One last, rather odd issue I’m running into with this. I am able to get the Dimensions to populate in Revit with the sketch below. However I have to play with the Boolean on the “Element.SelectInView” node, flipping it from True to False and running Dynamo each time I do.
By the looks of it Dynamo is trying to generate the dimensions before it’s generated the Reference Planes. I’ve tried putting a Pause/Wait node in there via Clockwork, but to no avail. Any ideas?
Use Dynamo Player.
Same results with Dynamo Player, unfortunately.
Remove boolean from “Element.SelectInView” node.
What type of elements does Dimension.ByElement accept? It seems to work fine for walls, grids, etc. But I can’t get it to work for families. It returns an error:
“Warning: Dimension.ByElements operation failed. The references are not geometric references. Parameter name: references”
Line based. Unfortunately that is what we have so far in Revit API 
That sucks. And I guess if you do a workaround by adding in a detail line it will break the relationship with the non-line based element and opens up a whole can of worms in terms of coordination.
How could I dimension with a line based element, for example a duct or a pipe. It works for the centerline, but if I want to dimension to one edge of the element, how could I do that?.
Thanks a lot. image|564x472
luiggi,
You could have Dynamo place a perpendicular reference plane at the ends of your ductwork, then dimension to that.
