1. ## Clearance Adaptive Family for CT Fittings

Hi everyone,

I've been struggling with this problem for a couple of days, but I couldn't find a solution, maybe someone over here can help me to solve this issue. I am trying to create an adaptive family driven by two points (2 adaptive points + 1 normal point) and an angle parameter, in order to create an arch which will follow the centerline of a cable tray fitting. The arch will be the host for a profile which will define my clearance family. The purpose of this is to automatically place the clearance with Dynamo. Please let me know if this is possible. Any help or guidance will be highly appreciated.
I attached the progress I made so far.

2. Hello, Adriangrosu2097, welcome to Revitforum

Adaptive points cannot be driven by dimensions as shown in that family. Maybe the clearance can be modeled with other simpler methods, maybe a line based generic family following the cable tray? More information would be useful. Please post a sketch that illustrates the desired result.

3. Hello Alfredo,

I have attached an image of what I want to achieve, considering that cable tray fittings don't have the same angle every time I think adaptive families is what suits best in this case, but I am open to suggestions.
I think this can be solved with some trigonometry, but my math is really bad.
Thank you for your timeCable Tray Fittings Clearance.pdf!

4. There is a simpler way to model that clearance volume without going to adaptive families and Dynamo. It could be done as shown in this image, using a model in-place sweep solid with a material and subcategory for clearance. You need to be aware that this will create additional model elements that you may need to hide from some views, using a subcategory as "Clearance".

"A" is the path, which is created by model lines by picking lines from the single line representation of the cable-tray. The curve of the elbows in the path need to be done with the fillet tool.

"B" is the profile of the sweep. This can be a sketch or a parametric profile family.

Then, you complete the sweep, and set it to that Clearance category.

5. Interesting... personally I would have just put extrusions with the Clearance sub category inside the Cable Tray Fittings
For the straight section I would add the clearance Sub Category, on each end of the fitting, as an extrusion with variable length. Then add some reference lines with grips to stretch/align to the ends of the cable tray run.
Simpler than adaptive family, the length could still be parametricaly set, can still be adjusted manually if changes are made in the model, and if the cable tray is moved it will move with it.
Many ways to do the same thing
