Compress shape geometry files

You can compress shape geometry files by converting the files from .xml format to compressed format .tez. Using the .tez format saves disk space.

In Tekla Model Sharing models, the shape geometry files are automatically converted from .xml to .tez when you use Tekla Structures 2018 or a newer version.

In older versions and in models that are not shared, you can manually compress the shape geometry files that are stored in the \ShapeGeometries subfolder in the current model folder. The files in the \Shapes subfolder will not be compressed.

If you have already used any of the shapes for items in the model, they will work the same way even after compression.


Compression is a permanent action, and you cannot undo it even if you do not save the model.

Do not compress shape geometry files if you need them in models that you will open using Tekla Structures 2017i or an older version. The .tez files do not work in those versions.

If your project, company, or environment uses a common location for shapes that are used in several Tekla Structures versions including 2017i and older, do not convert those shape geometry files to .tez format. Otherwise the shapes will not work in all versions.

How to compress shape geometry files

To compress existing shape geometry files, either re-import the original shape files, or use the Compress shape geometries application as follows:

  1. Open the model whose shape geometry files you want to compress.
  2. Click the Applications & components button in the side pane to open the Applications & components catalog.
  3. Search for the Compress shape geometries application, and then double-click to open it.
  4. In the Compress shape XML files to TEZ format dialog box, click Compress.
  5. Re-open the model.
