Morph or Object


If i build something out of a one piece morph and I need to place several hundreds of these identical morph elements, is it better for Archicad to turn the morph element into an object and place the objects, or is it about the same difference to just place the morph elements?

Hi! In my experience is better and faster to turn it into an object.  My guess is that once its an object the software handles lt like a referenced instance

As I see it, if those hundreds of objects are the same, i.e. they are instances of one single element, then it could be convenient to convert the initial morph into an Archicad-object. If the initial element changes, you can update the Archicad-object and all other objects will update.

Also, if I remember correctly, Archicad-objects are better handled by the computer in large quantities, than morphs.
If you keep all the elements as morphs, it might be cumbersome to change their geometry, but possible to control them individually.

Another tip, if the object is complex enough to be a performance hit, you might optimize it further by re-saving it in Binary format. (I think you have to save it to an external folder rather than the Embedded Library, in order to see this option.) This removes the ability to edit the GDL later, but does speed up the 3D.

Also, if it is very complex and you have many of them, you might save some rendering time if you don't need it to cast shadows, since these operations can require complex calculations. This also helps in the 3D window, or any elevation or section that is displaying shadows. A simple statement in the 3D script will turn it off.


I recall doing this years ago when we wanted to show a whole campus of buildings as context for a new building, so we saved the other buildings as binary objects and put those inert objects into our site model. The Shadow statement could easily be a parameter check box, so that they could be turned on if needed later.
