Vitruvius now has the ability to import and then convert your LEgacy StruCalc files (.prx) to Vitruvius files (.vtx). Please review the article linked below that describes how these files are imported before importing your files.
In order to import Legacy StruCalc files click on the file menu and select import. Then select StruCalc 10.0 Project ash shown below.
You will then be instructed to take a quick two-minute survey. This survey is required to use the importer as we truly appreciate your input in making our software better.
The survey will open in your web browser. Once you have completed the survey the file browser will open where you can select the Legacy StruCalc file (.prx). Once you have opened it the file will be converted and you will be prompted to save it as a Vitruvius project file (.vtx).
You should now be able to add members and work with the file in Vitruvius.
