The task Create a parametric model of a triquetra. The model must be controlled by two independent driving parameters (variables). By modifying these two driving parameters, the model must transition from State A to State B without breaking constraints, inverting, or producing errors. Fixed Dimens…

That’s a wrap on Challenge #1. Huge thanks to everyone who submitted. The response to Week 1 was fantastic and sets a great tone for the rest of the season. Before we get to the scores, here’s the solution: [Community Challenge | Parametric Sketching 1/5 Solution]

What does A variable represent?

Looks like it’s the thickness of the extruded sketch.

Dimension A represents the non-variable vertical dimension of the model.

Had a go. I don’t typically model on the basis of parametric dependencies. But it did give my brain a bit of a work out which was good. Sorry. Removed the screen shot. Didn’t see the requirement not to share.

Submission deadline is Sunday. There is still plenty of time to participate!

I barely ever model with variables (to my shame), so this was a fun little refresher on how to use them! Thanks Shapr team, these challenges are a great idea!
