You can insert a PDF file as a reference model to your Tekla Structures model. During import, Tekla Structures converts the PDF into the DXF format.
Insert a PDF file to a model
The Insert PDF Reference Model dialog box opens.
Tekla Structures converts the PDF into the DXF format. The conversion creates a DXF file for every inserted page. Tekla Structures saves the DXF files to the same folder where the PDF is.
Only vector graphics are converted, not raster graphics.
