Wall batt insulation automation using FamilyType by curve

Hello guys , so ive been trying to find a way on how to automate wall batt insulation on specific wall compoundlayer(insulation layer) centerline , ive read on some old posts where Mr @john_pierson confirmed that its possible by using line based detail family , so ive followed BIMPure’s video that mr @john_pierson has linked to me , and ive successfully made a parametric batt insulation family and nested it into a line based template family to make it line based , and the family works completly fine , except when i try to automate the family placement on dynamo , my revit crashes and i have to restart, soo appearantly something is wrong , here are my files , the revit file already has the insulation family in it , please can someone help me out ?? thanks!

ive already extracted the desired lines placement of the insulation family , just the placement is not happening

Automatic insulation per section view.dyn (25.1 KB)

Use the node DetailItem.ByCurve (I think that is the name). There should be an OOTB one and one in Clockwork

Why not stick to your original post?

because they are not the same , that one is about a visual filter for a specific wall layer , while this one automating 2d insulation drawing per view

I know the question is a little different,
but a solution with a 2D line was mentioned in your other post AFAIK (could be wrong).

Anyways. Do you still looking for a solution for your other post too or are you moving away from that idea? :sweat_smile:

i wish i found a 2d lines solution , where is it? ofcourse im interested!

To stick to the question in this topic.

My guess is you can’t use the OOTB project insulation. In the video a Line Based Family was
created to resemble the insulation line you can find it the project by the looks of it.
I might be wrong in my assumption.

yes i also created my own line based family and still wont work in dynamo thats my problem

Sorry, missed that (part).
You get no warning or anything?
When you have a look at the last node.
Does it show anything? Or null or something?

here i tried it with the one from clockwork , it gives nul

when i try with familyinstance by line dynamo crashes immediatly no warning no nothing , nothing shows

I guess you can right click that custom node and copy what there to your workspace and maybe you can see whats wrong then.

Maybe it is Python related?

Also. Were you able to find this?

DetailItem.ByCurve (I think that is the name).

im not using python , and that node is not available i found this tho and it gave nul

im not using python

I didn’t mean you :wink:, but there could be Python code in that custom node.

I think you can right click on that custon mode and select edit to see what is in there.

sorry but theres no edit options when i right click on it

What Revit version are you using?

i have no edit option available , also which node you using? im using revit 2025

Did you try FamilyInstance.ByCurve too?

My screenshot came from that node.

Do you have these packages?

yes it gives null
