Carlson CADnet to create CAD from non-CAD documents Carlson CADnet

First released as a separate module in 2014, Carlson CADnet allows users to create CAD from non-CAD documents such as PDFs, raster images, and paper plans. CAD text can also be generated from raster images with CADnet’s built-in Optical Character Recognition (OCR).

CADnet gives users the ability to import BIM models (doors, windows, walls, roofs, etc.) and bring them into CAD as CAD entities; plus, CADnet includes a routine to export surfaces into BIM.

Carlson CADnet supports AutoCAD® and comes with IntelliCAD® built-in. This is in addition to working on legacy AutoCAD versions.

Developed for more than 10 years within Takeoff,  Carlson’s popular site estimating and data prep software,Turn non-CAD into CAD with CADnet Carlson CADnet joins with Carlson GeoTech and Carlson Trench to provide customers the flexibility to obtain just the software they need at an affordable price. The three new modules can also be paired with Carlson Construction to form the all new Carlson Takeoff Suite, replacing the non-OEM version of Takeoff. (Note: the Carlson Takeoff  R-series with built-in AutoCAD remains the same.)

“These modules serve to answer the specific needs of geotechnicians, civil engineers, and construction professionals who may not have required all of  Takeoff’s many capabilities,” says Todd Carlson, product manager for Takeoff.
