CAD Availability

CAD is offered for the majority of Monroe's products. Monroe's CAD system is compatible with all CAD systems, including SolidWorks, AutoCAD, Inventor, and many others. Once you specify a part, you can select the CAD system you’re working in and hit a button to automatically download and insert the desired part directly into your design. Engineers can choose a variety of views—front or back, top or bottom, or right or left side.

Another very helpful feature of Monroe's CAD technology is that it generates and delivers the bill of materials for the part inserted, including the manufacturer’s name, the specific part number, and all of the detailed specifications for that part. This makes it easy for everyone involved in the buying process and virtually eliminates the possibility for error during specifying and purchasing.
