Curtain wall constraints

Curtain wall contraints

Curtain Walls have great built-in properties to constrain their behaviour in various ways. Using the pattern based (Grid Layouts) properties, entire walls can be modelled quickly.

But why not create your own custom built Curtain Walls that have irregular (non-pattern based) layouts? Through the use of Dimensions new rules can be built into your Curtain Walls?

Steps

  1. Start by modelling your Curtain Wall at a rough level which matches your design intent.
  2. Then apply some Dimensions to the Grid Lines in the Curtain Wall.
  3. With the Dimensions you can then equalise (EQ), and/or constrain (Pad Lock).

Looking at this example image you can see that the grids on the left are equalised. The door on the right is constrained to a fixed length.
As the length of the Curtain Wall increases/decreases, so too will the grids.

Extra Tip: Create a project file in your content library containing a variety of combinations of these custom Curtain Walls. These can then be copy/pasted into your project.
