This adds the ability to trigger CreateGeometry on the CT_Model GH component. The component will mostly function as before, except that when the CreateGeometry input parameter is set to False, it maintains the last geometry created, instead of reverting to beam.blanks. This allows the user to use a button input to trigger a recalculation of the geometry, which is useful when dealing with large models where each parameter change would otherwise trigger a new solution.

We could consider adding a reset button if it turns out users want to look at the beam.blanks too.

What type of change is this?

  • Bug fix in a backwards-compatible manner.
  • New feature in a backwards-compatible manner.
  • Breaking change: bug fix or new feature that involve incompatible API changes.
  • Other (e.g. doc update, configuration, etc)

Checklist

Put an x in the boxes that apply. You can also fill these out after creating the PR. If you're unsure about any of them, don't hesitate to ask. We're here to help! This is simply a reminder of what we are going to look for before merging your code.

  • I added a line to the CHANGELOG.md file in the Unreleased section under the most fitting heading (e.g. Added, Changed, Removed).
  • I ran all tests on my computer and it's all green (i.e. invoke test).
  • I ran lint on my computer and there are no errors (i.e. invoke lint).
  • I added new functions/classes and made them available on a second-level import, e.g. compas_timber.datastructures.Beam.
  • I have added tests that prove my fix is effective or that my feature works.
  • I have added necessary documentation (if appropriate)

wouldn't this just create an empty TimberModel every time the component is run? shouldn't the beams and joint etc. be added anyways (even if geometry is not calculated)

I added this so that every the model would persist, even if the inputs changed. I don't know of another way to do this.

Ok the other way would be to have the Scene be persistent/instantiated in the __init__(). I think we would then loose a lot of the speed improvements that we would otherwise gain from this PR
