I’ve just done my first-ever import of a Revit model with parametric objects. Some wrinkles:
The Wall types of Imported Wall types don’t show in Wall Styles: It seems to be work-around-able, because I can at least (only) edit the wall styles through a wall object’s Wall properties > more > edit wall style panel, but I’m wondering if them not showing in Wall Styles is an indication of a less-than-perfect import.
Windows came in as generic blocks, no parameters. The walls in which they are resident retain the holes the windows have cut in them.
Doors seem to have come in as doors, but they don’t respond to openingaperature %; they stay 0% no matter what the setting input field is set to. Editing the profile changes the opening size that the door cuts into the wall, but the door object elements all stay the same size they don’t enlarge in any way to fill the expanded opening.
@djhg The way Revit generates doors and windows (with their parts and dimensions) may differ from the way other programs, like VisualARQ, generates those objects. That means that just some specific information about those objects can be stored in the IFC file, such as the geometry, the parameters, or the opening profile. Other dynamic information such as the opening aperture, the profile dimensions, or the object component dimensions is lost in the exchange.
VisualARQ reads doors and windows coming from IFC files as object styles created from blocks. It also reads the opening profile so these openings perform the void into walls.
On the other hand, all the “static” data, should be preserved.
Depending on the object type (for example railings or stairs), it is not possible to regenerate these objects as VisualARQ styles. In those cases, VisualARQ reads those objects as Rhino geometry or blocks with the corresponding IFC Type assigned (ifcRailing or ifcStair). And this happens also with other objects that lack from the necessary information to be regenerated as VisualARQ objects.
Thanks. This is what I am experiencing, so I wanted to know if it was expected performance.
And in those cases, the polysurfaces within those blocks are nested as blocks also, but they don’t respond to my blockedit command, so as far as I can tell, they can’t be edited unless, instance by instance, each former parametric object is exploded, and each of its constituents exploded, and all of these objects edited individually or selected into groups. If there’s another way to work with these imported objects, please let me know. Not sure this is feasible for all but the smallest of projects.
Is my experience importing from Revit similair to what to expect exporting Va parametric objects to Revit, Autocad, and Vectorworks?
VisualARQ objects created as styles from blocks (such as the Furniture or Element objects, or the openings read from ifc files) can be edited with the blockedit command. This will edit the block assigned to their styles.
The rest of VisualARQ objects cannot be edited with the blockedit command. They can, but changes are not applied.
