Hi everyone! :)

This question is based on a previous question where i needed help with getting the shading system to work properly. I've looked into it a bit more and i found something that kinda needed a new post.

I found out that the reason why my Shading system did'nt work and why the error message statet that it was not attached to any windows, is because of the "Set Window to Wall Ratio by Facade" Measure (WWR) created by NREL.

I know that when using the measure, it removes the previous window construction and adds a new with the given sill height and WWR, which is fine but it does not add the objects that was attached to the previous window to the new window, meaning that settings such as Frame and Divider and shading control is lost in translation. An example is shown in the figure below:

With WWR Measure on the left. Without WWR Measure on the right. The models are completely identical aside from the WWR measure.

This is a huge problem when trying to conduct a parametric analysis of a building where the WWR measure is used and seeing as the WWR is an very important building paramter, this really needs to be fixed.

Hope someone is able to help with this or know how to change the measure to account for attached window objects :)
