How to create parameter (driving dimension) on a surface using SpaceClaim?

[henrique.geraissate]

Hello all,

I am trying to create a parameter to change the angle of an edge on a 2D surface in SpaceClaim, but whatever I do the "create parameter" button stays grayed out. 

 

I have tried with both the move and the pull tool, but neither seem to work.

Could some please shed a light on this?

Thanks in advance,
Henrique

You could move a vertex a distance to cause the angle of the lines connected to that vertex to change. This is an indirect way of controlling angle, but at least it can be parameterized.

Hi Peter,

Thank you for your continuous help here :)

This is a good workaround, but in my case the vertex translation to achieve the correct angles would be not exact numbers and for me defeats a little bit the purpose of the easiness of a parametric study. In the end, this is probably what I am going to do, but I was wondering if there is no other way to control the angle directly. I mean, I am pretty sure that in past versions we could do this with the move tool. Or am I tripping?

My second idea would be creating the geometry from scratch and record a script with variables I could then parametrize. But again, this feels too much work considering that most of my geometries I extract from a external CAD software.

In case you or someone else have further suggestions, I am happy to hear them.

Best,
Henrique

Hi Henrique,

If you switch to DesignModeler, that has the ability to control the angle of a line with a parameter directly.

Cheers,

That's great, I will give it a try.

It's been a while since I worked with DM though, and I remember having a hard time figuring it out hehe.

Thanks!
