The Combine Project tool for Vectorworks, ArchiCAD (from version 18, see ArchiCAD 18 Combine Project) and Allplan makes it possible to connect geometry based on either material or layer names, letting you organize and optimize a Project by reducing the total amount of objects to a minimum.
Scene files can be prepared in the native CAAD application by applying identical classes/layers or materials to the objects that you want to join in Cinema 4D. After importing the scene into Cinema 4D you can trigger the plugin by going to Pipeline / Combine Project.
Joins geometry to which a common material is applied
Joins geometry to which a common layer is applied.
Removes objects that have been unchecked in the Object Manager.
This option allows you to remove duplicate Texture and Selection tags that are applied to geometry objects, which improves viewport redraw speeds in Cinema 4D.
