Dealing with site objects that cannot be loaded

In rare situations, it may not be possible for Asta Powerproject 4D to load a site object when you attempt to add it to a 3D model. If this happens, a warning appears, informing you that the site object's 3D model could not be loaded.

This may happen in the following circumstances:

If you have made a copy of a site object's 3D model that you have already added to 3D model, then tried to add the copy as a site object.
If you have edited the site object in a CAD package and saved it as a similar (but slightly different) 3D model that uses the same product ID.
If the 3D model is invalid or corrupt.

If this happens, delete the site object's entry from the IFC Site Object library in Library Explorer to remove it completely from the project.
