snow Posted June 5, 2018 Share Posted June 5, 2018 I'm having trouble trying to round the edges of this object. I want the radius to be very small (0.0625") so I know that the size isn't the issue. I think it has to do with the extra segments, but I can't seem to get rid of them. I formed this object by union-ing the top with the two verticals. Object doctor isn't finding any problems and converting to facetted isn't helping. any thoughts? frame.fmz.zip Link to comment Share on other sites More sharing options...
snow Posted June 5, 2018 Author Share Posted June 5, 2018 update: I was able to get rid of the extra segments/points (copy segment sequence, remove points, imprint curve, stitch), but it still won't round. these steps should also ensure that the surfaces are flat.

Des Posted June 5, 2018 Share Posted June 5, 2018 I got it to work by re-spliting the shape where the joins were made, use the extend face tool to make sure the front and back faces are planer before the union. I swept the bottom curves again using the square section and an edge of the curve. Union everything together and the rounding works fine. I think the faces were not exactly aligned so there was a microscopic difference which made the rounding not work before. I use the extend face tool a lot before union-ing.

snow Posted June 6, 2018 Author Share Posted June 6, 2018 Thanks Des, much appreciated. It would be nice if Object Doctor was a bit more robust and could find these issues. I tried using some of the analysis tools but those didn't work well either. Link to comment Share on other sites More sharing options...
Des Posted June 6, 2018 Share Posted June 6, 2018 You're welcome Snow. The thing about Object Doctor is it has to guess a lot of the time which is normal. The "lines" on the faces were in fact micro steps in the geometry which is not necessarily bad, the doctor can determine those to be intentional. To be able to zoom right in and without changing the units accuracy in the file, just scale the offending object by say 1000 times. Then you can zoom in to see the mini-steps.

snow Posted June 6, 2018 Author Share Posted June 6, 2018 this is a good idea. I'll use it in the future when I have other issues. You're welcome Snow.

Tech Posted June 6, 2018 Share Posted June 6, 2018 As Des points out the Object Doctor does not see this as an issue because it could in fact be intentional. There is another workaround when these issues occur that can be useful in a mode complex model where it snot so easy to reconstruct: remove the offending edges (which removes the adjacent faces), reconstruct the complete face from the adjacent boundary and stitch in the new face. Here are the steps we used: Pick tool: set the topological level to segment. Pick the two "extra" edges. Delete Tool: click in the window to delete the pre-picked edges. Pick Tool: set the topological level to segment sequence. Pick on one of the now open edges and select the sequence of edges. Derive Segments tool: select the Join Selected Segments option and click to make a wire from the segment sequence. Cover Tool: select the wire object that was created and cover it. Stitch tool: stitch the new face back to the original object where the edges were removed. Repeat for the opposite side. Round Tool: round the entire object (tried 3/8" and 3/16"). We will investigate if this could be offered as a general tool in the future (maybe "merge faces" ). frame.cleaned.fmz.zip Link to comment Share on other sites More sharing options...
