I have Exported a DWG from another program to be used within VisualARQ. Is there a way to convert the meshes into VisualARQ components through grasshopper or rhino without redrawing components such as windows and doors.
Yes you can create styles from block definitions, however those are going to be static objects. You will find the option to specify a block in the last step of the dialog to create a new window or door style: “use a block in model view”
To define the opening hole you will need to specify as well in previous steps the profile shape (rectangular, circular, custom…) and its size.
If you want to have them parametric then you will need to recreate them from scratch, probably as Grasshopper styles to be able to customize them as much as you want.
