How to change bolt mark units from metric to imperial?

Question: 

We normally work with metric units but now we have a project (model) that uses imperial units. We have managed to switch our drawings to display most things in inches. However the bolt (hole) marks are still in millimeters. How to turn them to inches as well?

Answer:

You have two options:

1. You might want to use the Hole diameter attribute instead of using the Size attribute in bolt marks to show hole diameters. The Hole diameter attribute includes the option to change units on the bolt mark dialog, whereas the Size attribute doesn't have this option.

2. If you nonetheless want to use the Size attribute, you can copy the contentattributes.lst file from the environment you're using, e.g. C:\ProgramData\Trimble\Tekla Structures\2024.0\Environments\Finland\General\template\settings to the model folder and add the line written in green in the image below to the end of the file before the [BINDINGS] line. Add also the @\-characters preceding the files in the environment folder (the files without backslash prefixes). Next, reopen the model.

Note that you also need to update/recreate the bolt marks in the existing drawings to make the changes come into effect.
