The possible ways of using the model data, CAD drawings and reports received from another application in ARCHICAD are the following:
Use Merge to add the model or drawing content (or part of it) to the currently running ARCHICAD project. Merged model data are converted into native ARCHICAD elements, which can then be used as a protected or editable reference. The imported content, used as a reference, is separated from the host project elements, and can be displayed together or independently from the original project data by choosing a visualization technique.
As another “reference” possibility, you may open a received 3D model as a new ARCHICAD project first – e.g. to visually filter out the parts you will need – then link the project, or a part of it, to your current project as a Hotlinked Module, which will serve as (non-editable) content. Depending on the file formats you can also use XREF and/or Drawing connection to link external drawings into ARCHICAD projects.
The Open command launches a model or CAD drawing as a separate ARCHICAD file, independent of any other project currently open in ARCHICAD. This imported file can be added later as a reference to the appropriate part of another ARCHICAD project as mentioned before.
