Get started


To get started, install PREFAB and a compatible PDF viewer.

Install PREFAB​

PREFAB is installed through the StruSoft Installer. You can find it under the FEM-Design tab. Get ⧉ strusoft.com/software/strusoft-installer.

PREFAB in the StruSoft Installer

PDF viewers​

Due to the interactive features of the PDF, it is not compatible with all PDF viewers.

We recommend ⧉ PDF-XChange Editor, as it supports all the interactive features, PDF merging inside the viewer and Excel export from tables.

* Inserting PDFs into the original PREFAB PDF works, but multiple PREFAB PDFs can't be merged.

** PDF merging is included in PREFAB, and works with multiple PREFAB PDFs and normal PDFs.

*** Manual Ctrl+C, Ctrl+V to copy and insert.
