Converting Old DWG Drawings to 3D Models
If you’re a mechanical engineer who’s been around a while, you probably started your career designing in 2D CAD…usually AutoCAD. Even though you may have changed with the times and are now designing in 3D (often SolidWorks) you probably have many DWG files that you still retain. Many of your old DWG files are probably obsolete, i.e., designs of out-of-production products, parts and designs. But…there may be a treasure trove of older designs that are still relevant and that could save you time by reusing them. For instance:
- If you have common sets of 2D parts that are still in use, it goes without saying that they should be converted into 3D models right away. As part of the conversion process, you will want to ensure that the revisions are current and that they fit properly. Make any modifications that need to be made and calculate accurate assembly mass properties. Then you’ll have 3D parts ready to machine or to add to new designs.
- You may also have other parts sets that, while still in use, are not regularly called for. In this instance, wait until you need the part, then convert it. This saves time by converting only what you need, when you need it.
