When running CADX with the 'ArtiosCAD CAD-X Level 2' license, do you also need the 'ArtiosCAD Native PDF' to output PDF?
No. Native PDF is already included.
To output to PDF, you need the ARDPDF_Import_Export feature. This is included in the 'ArtiosCAD CAD-X Level 2' license. You will also find this ARDPDF_Import_Export increment in ArtiosCAD Connect xx.xx, ArtiosCAD Layout Optimizer, or any of the new bundles.
