What are the main differences between the 3D model file formats supported in the Studio products?
Answer
.dae
This is the extension of a standard Collada file and supported as import or export option in most 3D applications.
DAE files are XML files based on the Collada schema, and can be opened in any text editor.
DAE files are not self-contained, any referenced textures are not included in this file.
DAE files can be imported in Studio Toolkit to add a label or shrink sleeve, and are also the default export format for 3D models created by Toolkit for Labels in Adobe® Illustrator®.
DAE files can be opened or placed in Studio Designer and Studio Visualizer in case they have a properly defined Esko printable area.
DAE files can be imported in Store Visualizer without the need of an Esko printable area.
DAE files cannot be opened in Studio Viewer on Mac or Windows.
.zae
This is the extension of a Collada archive. The archive contains the actual 3D model DAE files, some manifest/root XML files and any textures that are referenced in the DAE files.
ZAE files can be renamed to .ZIP to unzip and find the DAE files to open in third party 3D applications.
ZAE files are supported by all Esko products, but to be able to open or load them in Studio Designer and Studio Visualizer, they need a properly defined Esko printable area.
ZAE files created by Esko Studio products can be viewed by the Studio Viewers.
.obj
This is the extension of a Wavefront 3D model, check the following article.
OBJ files are the best choice as output from 3D scanners if DAE is not available.
OBJ files can be opened with Studio Toolkit to add a label or shrink sleeve.
OBJ files can be imported in Store Visualizer.
.ard
This is the extension of an ArtiosCAD structure.
An ArtiosCAD structural design file can contain fold information, which will be kept and displayed in Studio products.
The Toolkit for Boxes plugin in Illustrator allows you to add/change fold information and export to a new ARD file. You can also open/import ARD files in the Toolkit application, i.e. to make compositions, but you will not be able to change the fold information. When saving/exporting an imported ARD in the Toolkit application, you will always write a ZAE Collada file, not an ARD file.
You can always render graphics on front- and backside of ARD components. In order to see a 3D representation including graphics in a Studio Viewer or Store Visualizer, you will need to export the result as a ZAE Collada file.
