I am just learning 3D printing, and I don't want to introduce changes when I've just started to become productive with Part Design. The changed Part Design workflow is what has stopped me from upgrading. I don't know if this was generated during the DXF import process, or if there's something wrong with the LibreCAD files, but I will try some other LibreCAD files and see if I learn anything. Thanks to your help I found the problem is apparently a "nuisance" arc that was generated at some point, and since it was collapsed, I couldn't see it or select it easily to find it. Then when I hit the Delete key it actually deleted it. So I had to drag a box around it, which selected the "arc", and it was also highlighted in the viewer, and I could delete it. That's because it was a collapsed arc, and clicking the endpoints of an arc and hitting delete doesn't delete it, and it doesn't highlight it in the viewer either. This was part of the layered problem.even when I was in sketch edit mode, I clicked on the dot and hit delete, and nothing would happen.
To delete the points (which are actually the end points of a collapsed arc) you must be in sketch edit mode. I was editing my previous post as you were posting. I can click on the dot, and it turns green, just like any other dot, but I can't delete it because pressing Delete deletes the whole sketch then. I can scroll through the list of sketches, and the lines in the drawing all light up, but there is nothing there at the bottom.Īfter I merge the sketches together, instantly I can see that dot at the bottom. I can also use Shift+B to drag a big box around the whole drawing, and the drawing is selected, but there is no dot like that.Īfter I convert all the arcs to sketches, I still don't find any sketch that corresponds to that dot, and the dot is still not visible anywhere. When I import the DXF, I can scroll through the list of the arcs and I never see anything like that dot at the bottom. There are no points, just 177 arcs and 1 circle. The imported DXF turns into 177 arcs and 1 circle (the center circle).
The part of my screenshot that I circled (dot/sots at the bottom) does not appear for me until I merge all the sketches together. I tried again with deleting the axle circle, with same results. You mention deleting a circle and two points on each other. Thank you for helping troubleshoot I am happy you were able to get it to work.

I have identified a weird dot in the sketcher view. So there is something wrong that I can't figure out, why the imported sprocket shape, even portions of it, are giving a broken face error, even when they portions are relatively simple shapes. I also tried to extrude just the tooth profile, with all the other lines converted to construction lines. I get a failed to validate broken face error even on a single cut-out shape. Then I did the same thing and tried to extrude one of the cut-out shapes by itself. To troubleshoot, I tried turning all lines into construction lines except the center circle. I don't see any obvious geometric things that would prevent extrusion (open gaps, crossed lines, concentric circles, etc. I cannot extrude the shape due to "unable to validate broken face" error. It seems very difficult to make this complex shape fully constrained. I am not sure if the shape has to be fully constrained in order to be extruded. Despite this, Sketcher still tells me my shape is un-constrained, with about 500 degrees of freedom. I use Sketch Validator to find about 177 missing coincidences. I use Sketcher to merge all the sketches into one big sketch I use Draft Workbench to convert the arcs to sketches (I also tried combining arcs first using the Up Convert tool in Draft, but I get an error that items cannot be upconverted) I create a DXF drawing of a sprocket in LibreCAD Please note this happens any time I have tried to import a DXF and extrude it, no matter how simple the DXF is.
