Import 3ds Max Files (.3ds)
With the help of 3DStudio In Add-On you will be able to convert .3ds files to ARCHICAD GDL objects. By default, it is not integrated into ARCHICAD’s interface.
Download and install “3DStudio In” Add-On
- You can download this Add-On amongst other Goodies by clicking on Help menu/ ARCHICAD Downloads option in ARCHICAD.
In the appearing Graphisoft download site please select the language of your ARCHICAD then the OS icon matching your computer to download the Goodies Installer.
- As of version 20 Goodies for ARCHICAD are available in one single installer package. During installation you can select which one(s) you want to install.
- Start the installer and follow the instructions. The add-on will be automatically loaded the next time you start ARCHICAD.
- The new commands will appear in the File / Interoperability / 3D Studio submenu.
Import a 3Ds File as GDL Object
The 3D Studio file to GDL object conversion process can be customized by the User.
- Select the 3ds file with the Import 3DS as GDL Object command.
- The add-on displays information about the original 3DS file:
- number of points, faces and object count
- object sizes (X dimension(A), Y dimension(B) and Height). You can modify these.
- Force smooth option: The add-on tries smoothing all object surfaces.
- Import hidden objects: Hidden objects will also be imported from the file.
- Use texture’s alpha channel: The transparency information will be imported from the 3D Studio file, if the related TGA/TIFF textures contain alpha channel information.
- Click OK.
- The add-on checks whether the 3DS file contains texture links. If the defined texture file does not exist next to the 3DS file, the program prompts the user to specify its location.
- During the conversion, the add-on copies all textures to the given destination folder alongside the converted GSM object.
- The add-on creates the new library part (open Object Tool’s Settings dialog) and places it in the Embedded Library . The name will be generated from the original .3ds file name (without the.3ds extension). At the end of the conversion, a message is shown:
- After import you can place the new object. You find it in the Embedded Library.
Input data: a .3ds file (3DS Studio file), and occasionally jpg or other texture files. Texture file formats must be one of the image formats ARCHICAD supports.
Output data: a .gsm file, and occasionally some texture files (jpg, gif, pict, …).
The result will be a fully customizable object regarding sizes and materials: Using the Override Surfaces option on the Model tab of the Object Selection Settings dialog you are able to reassign new surfaces to the object.
The conversion process is customizable with the File/ Interoperability / 3D Studio /3Ds to GDL Conversion Options command.
- The user can assign the correct x,y or z instead of the original (x=x, y=y, z=z) assignment. There can be a ‘-‘-sign before x, y or z. For example, when 3ds file is converted from Lightwave, the recommended assignment is: x=x, y=z, z=y.
- Scale: Sets how many millimeters correspond to a unit in the 3ds file.
- Decimals: Specifies the precision of the converted object’s size.
- Fit bottom to z=0: fit the object’s bottom to z=0.
- Fit object’s gravity point to (x=0, y=0): fit the object’s gravity point to (x=0, y=0) in the top view.
- Fit gravity point to 0 only when needed: this means that “fit gravity point to x=0, y=0” works only when the object in the 2D top view doesn’t contain the (x=0, y=0) point (the 2D origin).
Hotspots in 2D:
- Bounding box: Automatic ARCHICAD bounding box (this will also occur when no hotspots assigned for 2D)
- Zero point: x=0, y=0
- Outermost point: Top left, bottom left, top right, etc…. max. 8 hotspot points from among the object’s points
- Gravity point: The object’s gravity point
Note: The selected option results in hotspots in 3D too!
Hotspots in 3D:
- Bounding box: Maximum of 6 of the outermost points. Each of these hotspot points is a point on the object.
- Zero point: x=0, y=0, z=0
- Gravity point: The object’s gravity point

Export to 3DStudio File (.3ds)
3DStudio File (*.3ds) format can be saved from ARCHICAD by default; it is not necessary to have any add-on installed.
- Open the model you would like to export in 3D view.
- Choose File / Save as… command and select file type 3DStudio File (*.3ds) format and save your model.
- While saving a 3DS file you have to specify in millimeters or inches the unit to which dimensions of the model should be converted to in the resulting 3DS file.
- Originally 3D Studio was always expecting dimension data in inches. That was its default dimension unit. In 3D Studio Max, however, there is a setting in Preferences called ‘Default Units’. Because of this the conversion can go wrong if not the correct procedure is followed. There is a checkbox in 3D Studio MAX: Convert Units:
- When this checkbox is unselected, 3DS MAX assumes the units in the imported file match the current system unit of 3DS MAX and doesn’t convert the units. If the units set in 3DS MAX and during ARCHICAD export are different, you have to use the Convert Units option in 3DS MAX. If the units are set to match, you should leave the checkbox unchecked.
