Issues found while working with Grasshopper Connection and Archicad

[Nader Belal]

Hi there,

I have been working on a project for creating a GDL object that needed the use of Grasshopper connections and I believe that the issues I have found lately should be addressed to improve the workflow experience (ps: I do consider that some of these issues could be the result of my PC and installed programs):

1. Archicad GH components do not play nice with clustered definitions. It either model a duplicate of the intended element geometry or the crashes.
2. Archicad GH opening components do not have an entry for openings' heights if a Favourite is used. The only way I found to change it's position is to deconstruct the opening element, reconstruct the the opening settings with the intended height, then redo it again. As you can see that is not efficient and is prone to make the PC crash.
3. Related to previous point: AC opening gh components do not play nice with GH coordinate transformation component. I believe this should be check out.
4. All element component has a boolean parameter to sync the element with Archicad which is a Great Addition, but I have found out this weekend that I wished I could have access to the elements' geometry in Rhino without the need to send it continuously to Archicad. So I would like to see another Boolean parameter that even when that GH component is being synced with Archicad, if turned off, it will not send that geometry yet. Sometimes we do need to make modifications.
5. Some definitions may need to use different filtering GH component before sending it to the intended AC GH component, but when I plug a panel to see which resulting option was used, I get a <null>, it would be nice if we could find a solution to that.
6. Some AC GH component do raise an error message because the data entry was a text or a number, I believe that is due to the data type that the AC GH component was expecting that should have not been a text or a number. It would be nice if that issue was looked upon.

Thank you in advance
