2D dwg / dxf to 3D CAD conversion

convert 2D dwg, dxf to 3D CAD

For many companies and users that stand before the question of changing the CAD Software from 2D to 3D have to answer one Question: "is it worth it?".
This answer cannot be generalized with a simple yes but should rather be case and need sensitive. Ultimately every CAD Software offers the ability to create technical drawings of a part or component.

the question of how is however the deciding factor

The main difference of 3D CAD compared to 2D is the principal of parametric drafting and modeling. On our 3D drafting & design page we outlined basic features and design methods.

"intelligent" parts and components

In 2D CAD Systems all relevant information is saved on the sheet itself. In a parametric CAD all relevant info is saved in the component. Should a change or update of a component be necessary then this is done in the component. All assemblies that use this component are updated automatically.
A further advantage is the definition of features in a component. In 2D CAD features like chamfer, threaded holes etc. are only identified by appropriate annotations in the drawing. In parametric 3D these features are specified in the component.


The principal of parametric modeling and the use of semantic features opens a world of new possibilities and opportunities. These features make a part, component and assemblies "intelligent".

Import 2D dwg / dxf or start from scratch?

As a rule of thumb it should be noted that the conversion of 2D dwg or dxf files is faster than to start from scratch. In the images shown on this page such a process can be seen.
The first image is the 2D dwg file that is converted to a 3D model. Since all production drawings show the profile of a part it would be a waste and non efficient not to use this info.

In the second image the profile used to create the 3D part can be seen. This profile also represents the only info used for the import and conversion of the dwg / dxf file into a 3D model.

Companies that have created 3D dxf files will find it even easier to convert to parametric modeling. It is possible to import and convert the 3D dxf file directly into a SolidWorks part document.

The advantages of parametric modeling are significant. We would gladly be of service and support your efforts move from 2D to parametric 3D!
