Another method would be a scribe feature similar to cosmetic centerlines that allows for more complex geometry. My thoughts on how Autodesk could integrate this into sheet metal is to copy the punch tool to a new scribe (function or module?) add in an additional selection box at the flat pattern definition. dwg format as we use ProNest 2020 along with Inventor 2020. Once the flat pattern view is inserted into the model space of the drawing it can be inserted into a nest with the correct layer settings. With this setup it turns all internal bends or cosmetic center lines into scribes along with any punch tool with a simplified sketch. It involves setting up a simplified sketch representation, then using the Inventor Dwg format to create a drawing with the burn & scribe layers added, then changing the layer of the object default styles. It takes some setup in making the punch tool and sadly you cannot use the punch tool for much else once you do it. I've been able to create scribes by using the punch tool feature. The third and fourth shared video shows your competitors solid edge in SolidWorks on how they have an edge function within their software The second video that I have shared shows you how etching is being used on metal. The reason why it is necessary to export the inventor file out this way is because all commands that inventor uses are identified by the nesting software as a cut command. The first is called "Inventor Etch" which explains what Paul is talking about exporting parts out into AutoCAD and then identifying the etch function by creating an AutoCAD layer for etching. I have below a few shared YouTube videos that may help you. The purpose of etching is to identify second processes such as machining holes or locating we're parts would be welded together. Cincinnati Incorporated offers their own nesting program. There are other nesting software such as PEP. The nesting software that I've used has been sigma nest but sigma nest offers different modules so we have the basic module because of the cost. I have been going through the same problem with creating an etch that Paul is describing. I am sure many others would find this feature useful as well. ![]() I may put this on the forum at Autodesk as well just wanted to see if I am missing anything currently. It would be really nice if in the “Flat Pattern DXF Export Options” Inventor could recognize non through cuts as well and export them as a different feature/layer/line type. This works but requires a sketch in the flat pattern be created and the geometry projected. We found a work around that requires an extra step involving us going to the flat pattern, creating a sketch on the front of the flat pattern and projecting the partial cuts then when saving the DXF we use the filters in “Flat Pattern DXF Export Options” we choose IV_UNCONSUMED SKETCHES and change the color and linet ype to differentiate between through holes and etched holes. ![]() ![]() In the model we do a small cut (less than the material thickness) which shows where the etching should be but when exporting the DXF file for our laser programmer it is difficult to differentiate which is a through hole and which is a partial cut. When laser cutting our sheet metal parts we often want to “etch” a line or circle on the part to locate another part for welding. Was wondering if a request could be made to improve Inventor if possible or if a feature exists that I might be overlooking. I'm not necessarily saying your idea is inherently bad, but depending on what your software's capabilities are, you may already be able to get what you want without the requested new feature. You might want to look into whether something similar is possible with your software. But we achieve what you're trying to get, without taking the patterns into AutoCAD. We don't have to actually emboss the features (and in fact it causes problems with detecting the plate thickness if we try to). Then in the nesting software, we set it to look for that sketch name for the Marking process, similar to how layers would be used in an AutoCAD-based pattern. In our software (SigmaNEST), we are able to create a sketch on the Inventor part file (if sheet metal, the sketch has to be in the Flat Pattern), and give it a particular name. We don't have a laser, but we do have a burn table that has marking capabilities. Not sure if this helps (don't know what nesting software you're using for your laser cutter). ![]()
