Hardware Requirements

We recommend a Desktop-PC, Laptop, or Tablet-PC with a standard processor, 4GB of RAM or more, and a screen resolution of 1024 x 768 pixels or more. For bigger and more complex CAD models, we recommend a graphics card which supports OpenGL 3.3 or higher

The speed of opening and converting CAD files using the 3D-Tool Advanced and Premium interfaces depends on the processor speed and the amount of available RAM. With increasing size CAD models require more computing power and main memory. For big and complex CAD models we recommend a fast modern processor and 8GB of RAM or more.
