Solid imported by Dynamo doesn't cut on sections

[Omer4ZWBQ]

Hello everyone,

I've been working with Dynamo for quite a while, but for the first time I imported a solid created geometry into my project. The solid is a Column with a VERY distinct shape that is much easier to create and manipulate by Dynamo than it would been by a classic Generic Model family.

After the column is imported it appears in place as intended, but whichever section cuts it, the column doesn't cut properly in the desired location and I can see the part of the column that "gets out of the screen".

I tried exploding the column but it basically deletes it entirely with the warning "Import contained some 3D data or points which can't be exploded."

I read that imported objects could have this issue, but since Dynamo is a built in Revit product I assumed that they

can work with each other.

I added the dyn file which creates the geometry and imports the object

Any help would be appreciated, as making the column by a Revit generic model family with the flexibility as in Dynamo is quite a challenge

See if this gets you what you want.

Left  FamilyType.ByGeometry

Right ImportInstance.ByGeometry

For convenience I unioned the different solids. I set the category to generic model, could also be another category.

It creates a family type in the familybrowser (named TEST) under generic models. You have to place it yourself. You could modify the script to place it on a certain location.

Thanks a lot for your assistance! It seems to be the right direction, however the inserted family have some sort of a problem in it, the geometry of the column is incomplete and is hollow

I see that in the comparison picture it looks ok for you, so I can't understand where the issue is as I tried copying the nodes exactly the same

Also the inserted family has a reference point unrelated to the original center point, it seems to be the bottom left point of the bounding box, I need to move the family to its desired location so I first have to understand where exactly it is located.

Again thank you very much for your help!

I can not really help you there. I used Revit 2024 (Dynamo DYNAMO v.2.19.3) and I do not see the hollow elements. Hereunder the elements by both methods.

For placement you have to figure where to place it in the project and taking into account the origin point in the family.

At the moment it looks like this inside the family.

So you might some different placement offsets or build the elements differently in Dynamo so that the origin point of the family is more logical. But that is up to you. The script is too extensive to quickly analyze how elements are build up and placement is determined.
