Aspiring design or hobby engineers can save money while getting a simple introduction to 3D with the sheet-based modelling approach supported by the free MEDUSA4 Personal drafting software.

The powerful freeware can be used to edit DXF/DWGs and create 3D models from 2D drawings. Challenging economic times call for greater creativity. CAD Schroer has welcome news for aspiring designers and hobby engineers: Those looking for a powerful, free DXF/DWG editor, can even use MEDUSA4 Personal to turn existing drawings into 3D models.
CAD Schroer, long in the business of simplifying the route from 2D to 3D, provides the free MEDUSA4 Personal 2D/3D CAD software for non-commercial use. One of the benefits of this fully-fledged design engineering tool is its excellent DXF/DWG interface, which enables users to easily edit existing drawings. It’s also ideal for those who want to dip their toes into the world of 3D modelling.

From 2D DXF/DWG to 3D

MEDUSA4 Personal’s “sheet-based modelling” approach lets designers easily turn a drawing into a 3D model. “People who are used to working in a 2D environment really like this approach,” says CAD Schroer Technical Support Consultant Alan Liddle. “You need to have a concept of height and depth, but you don’t need any expert modelling skills or the same spatial awareness as with complex 3D modelling tools – and there isn’t a steep learning curve. Our DWG/DXF interface is very accurate, so that you start off with an intelligent bit of geometry which you can then edit and model.”

DXF to 3D model demo video

In a demo video just released, users can see this approach in action: A DXF of a centrifuge pump with electric motor and gear box is opened in MEDUSA4 Personal, and edited on a 3D sheet, displaying plan, front and side views. “We utilise the profile of the components we wish to model in plan view, defining the X and Y coordinates,” Alan explains. “A link line to one of the other views is used to define the Z dimension. The part is then sent to the software’s modeller, which creates a solid model users can view and manipulate. We use solid sweeps to define the flanges, feet and legs of the assembly. For the pump body and motor we define a volume of revolution by rotating the profile around the centre line. Finally, Boolean operations are used to join together the defined 3D components into a single unit.”
