Hi,
PDFCreator (by us, pdfforge) has always been a virtual printer and never included any measurement tools.
Do you perhaps mean PDF Architect? PDF Architect contains a “ruler” and a “grid” tool, but I am not sure if those are enough for technical construction drawings.
Or could it have been software by a different company, as the name PDFCreator is to general to reserve rights for it?
E.g. if it was PDF Creator with a space in the name, it wasn’t our product.
If you purchased our PDFCreator or PDF Architect within the last 30 days and aren’t happy with your purchase, just let us know and we will give you a full refund.
Best regards,
Robin
