Merging Files to ArchiCAD

Use the File > File Special > Merge command to paste the elements of another ArchiCAD Project, a Module, DWF/DWG/DXF, HPGL (.plt) file, IFC file, or other image or model-type file into ArchiCAD.

Files can be merged into either the current Floor Plan, the currently open Section/Elevation/IE, 3D Document or Detail/Worksheet window.

Note: When merging a Module into a Section/Elevation/IE or 3D Document window, only 2D Elements will be pasted.

The elements of the merged files will become independent of each other after being placed. You can place the same elements repeatedly with the Paste command.

When merging a Project or Module, you can drag, rotate and mirror it before placing it to the final location. Until the file is placed, its elements will be surrounded by a dashed rectangle. Click within the rectangle to move the elements to the desired position. Click outside the rectangle, or click OK from the context menu (or the Control Box) to place the elements.

Merging and Story Structure

When merging a Project or Module file, ArchiCAD matches the stories of the merged (imported) file to the current (open) one. When you merge a multistory building into your current Floor Plan, ArchiCAD will ask you to define which story from the imported file will match the story you are working on, and it will also suggest a possible match.

If you do not have enough stories in your current plan to accommodate all the merged ones, ArchiCAD will automatically create the missing stories.

Note: You cannot merge multistory elements or modules into 2D windows other than the Floor Plan.

Note: There is a difference between merging a multistory project, and placing a multistory Hotlinked Module. If the host project contains fewer stories than Hotlinked Module you are placing, the module stories which do not “fit” in the host project will not be placed.

Merged Geometry of Top Linked Elements

Adjust Elements’ Home + Top links to Current story structure: Top Linked elements will stretch or shrink to match the corresponding story structure of the current file. (Doors/Windows whose sill or header is linked to a particular story will adjust to the current file’s story structure.)

Remove Elements’ Top Links and use original height: Top Linked elements will be transformed into “Not Linked” elements, and will retain their fixed original heights. (Doors/Windows whose sill or header was linked to a particular story in the merged file will lose the story link, and instead will be linked to the Wall base.)

Merging and Attributes

Since attributes (Layers, Surfaces, Line Types, Fill Types, etc.) are identified by their names, the following rules are observed:

If the name of the attribute is the same in the two ArchiCAD Projects, the merged (imported) elements will inherit the attributes of the current Project.

If the name of an attribute for the merged Project is not present in the current one, this attribute is appended to the current Project’s attribute set to accommodate the new names.

Merge DXF/DWG File

If you merge a dxf/dwg file, the Merge DXF-DWG dialog box appears.

See Merge DXF-DWG.

Merge IFC File

For details, see Import Functions.

Merge Stereolithography (.stl) File

See Stereolithography (.stl).

Merge SketchUp (.skp) File

Use File > File Special > Merge to merge content from an .skp file into an existing ArchiCAD model. The Floor Plan must be active in ArchiCAD.

Since the ArchiCAD model already contains project location information, you are asked in a dialog how to handle the two sets of coordinates (ArchiCAD and SketchUp):

Overwrite the ArchiCAD information with the SketchUp information

Ignore the SketchUp information. Your Project Location information remains as-is, and you can place the imported object anywhere you wish: drag the appearing boundary box and click to place.

Place the incoming information relative to the existing coordinates. The imported object will be placed in its true location relative to your project origin.

Step by Step Guide for Merging a Google Earth Snapshot into ArchiCAD using SketchUp

1.Open a project in ArchiCAD

2.Open the Project Location dialog box, check that it has the desired longitude and latitude set

3.Press the ‘Export’ button

4.Set the format to ‘SketchUp file’

5.Give a new file name and press ‘Save’

6.Close the ‘Project Location’ dialog box.

7.Using SketchUp (downloadable from http://www.sketchup.com) open the file saved in step 5

8.Open up the ‘Model Info’ dialog and check that the ‘Geo-location’ is set

9.If not (if using MacOS), click the ‘Set Manual Location…’ button: the correct longitude and latitude should be displayed; press OK

10.Use SketchUp > File > Geo-Location > Add More Imagery… to open the ‘Add Location’ dialog box; the Google Earth image should be centered at the ArchiCAD origin

11.Zoom in or out as desired

12.‘Select ‘Region’ and ‘Grab’ it

13.The same region should now be visible in the SketchUp file viewer

14.Save the changes to the .skp file

15.Return to your ArchiCAD project file

16.With the ‘Ground floor’ view open, select File > File special > Merge

17.Select the .skp file you just saved in step 14

18.A dialog box containing three toggle buttons should appear. Choose the ‘Place the new geometry relative to existing coordinates’ option and press OK

19.The Google Earth snapshot should now appear in the ArchiCAD project

20.Open a 3D view and fit to see the snapshot in detail

Merge Google Earth (.kmz) File

Use File > File Special > Merge to merge content from a .kmz file into an existing ArchiCAD model.

Important: Make sure that the merged Google Earth model to be merged

-contains only a single location pin

-uses the Absolute method to define its altitude (see below).

Altitude Settings

The merging process will check the model’s altitude settings. In Google Earth, there are several ways to export altitude data, but ArchiCAD supports only the “Absolute altitude” method.

If your .kmz file contains alternative altitude settings (either “Clamped to ground” or “Relative to ground”), an information dialog appears: you should reexport the model from Google Earth using the Absolute altitude method.

Alternatively, click Continue to place the imported GDL object at the 0 level of the current story in ArchiCAD.

Location Information

Since the ArchiCAD model already contains project location information, you are asked in a dialog how to handle the two sets of coordinates (ArchiCAD and Google Earth):

Overwrite the ArchiCAD information with the Google Earth information

Ignore the Google Earth information. Your Project Location information remains as-is, and you can place the imported object anywhere you wish: drag the appearing boundary box and click to place.

Place the incoming information relative to the existing coordinates. The imported object will be placed in its true location relative to your project origin.

Merging Image-Type Files

You can merge an image-type file into your ArchiCAD Project. (These include documents created in drawing or painting programs; 3D views and elevations saved in picture format; PhotoRenderings saved only in picture format.) Before choosing Merge for an image-type file, you can define its size on the plan in advance: Choose the Marquee tool and draw a Marquee of the desired size and position.

See also Marquee Area.

The merged image will fit into this rectangle.

MarqueeMerge2.png 

Note: Be careful to draw the Marquee with the same proportions as the original picture, otherwise the figure will be distorted.

SketchUp: Export and Import Limitations

SketchUp models can contain two types of object faces and edges. Currently, standalone SketchUp edges are not imported into ArchiCAD.

In SketchUp a single face can have different front and back colors and textures. In ArchiCAD a GDL face can only have one color and texture defined. ArchiCAD’s import function defaults to the front face’s properties unless the back face has texture defined and the front face doesn’t.

SketchUp models containing faces that are very irregular (outside boundary crossing itself, i.e. figure of eight) or faces that contain holes may be imperfectly imported into ArchiCAD

Some SketchUp faces get imported into ArchiCAD but lose their texture

There is a flag in the .skp format to state whether the file is Geo-referenced or not. The MacOS version of ArchiCAD is unable to correctly set this flag and the exported .skp files may require that the flag be manually turned on (the longitude and latitude are always correctly set in the .skp file).

Google Earth: Export and Import Limitations

Occasionally Google Earth .kmz files contain triangular faces with very small angles that are not imported into ArchiCAD

If the ArchiCAD 3D view is such that the camera is positioned underground, then the view shown in Google Earth isn’t the same as in ArchiCAD.
