Subassembly Composer - Link with variable length along corridor

[Alex_Figueres]

Hi!

I want to create a custom assembly for modelling sunken curbs. I have earlier modelled such corridors with a third-party application that allows me to create subassemblies where dimensions vary along its region's lenght. Then I can create regular curb (regions 1 and 5) and sunken curb (region 3) with constant dimensions, but also two regions where dimensions vary (region 2 from h=120mm to h=60mm, and region 4 with the opposite).

I only have to create four subassemblies and a corridor with five regions, and I can further edit the whole thing just by moving the grips of each region. 

Note: the red line is the featureline used as Baseline for the corridor, which has a constant elevation.

Is ther a way to create an subassembly in Subassembly Composer so that a link's length varies along the corridor/region?

Maybe some workaround?

Some  key-word I could yse to google further?

@KMercier_C3D , @samir_rezk  or any other gurus out there? Thank you in advance for your help! 🙂

Hi @Alex_Figueres watch this AUniversity class which might give you the ideas you need to implement

Autodesk University Class: AutoCAD Civil 3D and Subassembly Composer-Real-World-Practice Tips and Tricks 

I hope this helps

Thank you @ecfernandez , this was exactly what I was looking for. And thank you to @Jowenn.Lua for an awesom AU class!

In case someone else needs to create a similar subassembly, the key is to create a variable in SAC that interpolates dimensions along the Regions length, ie:

Then you have a link with an DeltaX varying from 1 to 2 along the region the subassembly is applied to.

WONDERFUL!

Good to know you solved it @Alex_Figueres . I'm always happy to help 🙂

and, yes, that's a great class!

Bye, best regards!
