Edge Status of Objects

You are able to control the smoothing of the object’s polygons at the edges.


To adjust the angle at which two adjoining polygons will be smoothed at the edges, do the following:

1.Select the object in CINEMA 4D Exchange.

2.Right-click on the object in the Object Manager and select the “Phong” tag from the CINEMA 4D Exchange Tags.


3.Click on the appearing Tag marker in the Object Manager.


4.Its properties will appear in the Attribute Manager.

5.Switch Angle limit on and set your angle. The entered number will be the maximum angle at which two surfaces are smoothed into each other.

Number of Polygons in Objects

The number of polygons in your CINEMA 4D Exchange objects greatly influences the speed of your ARCHICAD. To check the number of polygons:

1.Select all your objects, except the ARCHICAD environment, in the Object Manager

2.Right-click on them and select Object Information

3.The number of polygons is displayed in the appearing dialog


The fewer polygons the objects have, the faster ARCHICAD will be. If you think your object is too big, you have several options for reducing the number of polygons in CINEMA 4D Exchange prior to returning the object to ARCHICAD:

•The Optimize command will throw away polygons/points/edges which are closer than the entered Tolerance value.


Polygon Reduction reduces the number of polygons for the objects to which it is applied.

According to our tests, objects containing fewer than 20,000 polygons work well in ARCHICAD. Of course, placing multiple objects will increase calculation time.

ARCHICAD Object Display Settings

The floor plan symbol of the created CINEMA 4D Exchange objects can be fine-tuned in ARCHICAD using the following object settings:

1.Floor Plan display – choose one of the 5 options.


2.Model Behavior – By default, the object coming back from CINEMA 4D Exchange contains two 3D geometry models.

•The Solid model can be used in Solid Element Operations, but has restrictions on displayable Surfaces, so texturing may differ from the one used in CINEMA 4D Exchange.

•The Texture model stores the custom texture information you assigned to certain surfaces of the object in CINEMA 4D Exchange, so the correctness of the displayed textures is limited only by the Internal Rendering Engine of ARCHICAD. To avoid duplicated geometry in the project, which may cause performance problems, select one of these behaviors.


3.2D Representation – Depending on the Floor plan display selected, different parameters may be listed here.
