Every day we open/save hundreds of drawing and production PDF’s, which previously used an inordinate amount of our company’s engineering capacity. CADSharp’s seamless add-in automates it all with mere keystrokes, increasing productivity by 30% and synchronizing manufacturing drawings in real-time. These guys are the real deal and we look forward to our next project with them.

We were in need of a tool which extracts custom properties from thousands of SolidWorks parts into an Excel spreadsheet. CADSharp provided us with an easy to handle and really fine working solution which saved us much time. The support and reaction time of CADSharp was first class and we could start the import into our ERP much earlier than expected. We would like to thank CADSharp and will be happy to work with them again.

I ran the add-in and I’m extremely impressed. I showed my boss and he couldn’t believe what he saw. Back in the day, he used to pay a guy to hand draw each part in Autocad LT. This makes that entire job obsolete, lowering the bottom line for the company. Literally amazing! I believe this will come to be something I don’t know how I ever lived without.

Case Studies

In 2018, CADSharp wrote a SOLIDWORKS PDM addin that eliminated duplicate entry, reduced user errors, and streamlined data transmission within TMC Ametek’s organization. You can learn about the design of this addin and how it solved their problem by reading the full case study here.

I would estimate that CADSharp’s work they performed for us reduced our new order processing and handling
by 30% while at the same time improving the quality and usefulness of our data. Over time I see that number growing even higher as we master these new tools. Overall the changes have been fantastic, and puts us in a position to grow vs. being constrained
