I will go on strike and read that section ! I must be allowed training.
After creating a patchwork quilt of sweep2 surfaces, should I just select them all and use Join then showedge and naked edges and tackle those with MatchSrf or just use MatchSrf from the outset working my way across them ?
For some reason I cant get MatchSrf to work at most times so reach for the next thing I think of and that is JoinEdge. The item I have just created after weeks of work/research is a patchwork quilt of many surfaces all sweep2. Given the complexity of the object it was THE ONLY WAY. I havent then trimmed any edges. MatchSrf should work on those ? p59 onwards and revisit the project !
As such I am puzzled that as the surfaces share rails, joinEdge declares 0.05 on one and 1.2 on another. I then think I can be sure of joints where it asks permission to just exceed tolerance by a fraction, for our job, no issue at all.
I will revisit the original and try again for MatchSrf but if MatchSrf wont work and I have naked edges I think back to a post by Pascal where naked edges then JoinEdge was used.
Faking distance is not good, something that takes my surface edges and extends them is good…MatchSrf.
Would I be right in saying that JoinEdge will cause further nasties when I come to offset 2mm the cowling inwards.
For the end result after offset2mm in ghost view I had a few very small dark triangles and odd shapes that I couldnt edit out. It also has caused odd junctions and other imperfections to my original complex patchwork quilt of surfaces. Using MatchSrf on just this shape that I have rebuilt with CurvatureGraph and NetworkSrf sees one part of it join and the other half go twisted on me.
see pics and file. The result after offsetSrf, note the oddment ‘E’ and distort to end of what was an elipse. Careful work ends up like this after offset. was that due to JoinEdge before offset ? I will have to experiment. The sweeps were ’ to point’ in this area.
I select the one side of this easter egg shape ‘A’, then select first segment ‘B’, then next ‘C’ and squiffo before I get to D, various settings make no difference. JoinEdge simply works so is easy to use unfortunately. 30 mins struggling on one shape, hate to think how long the entire cowling would take.
After OffsetSrf on my complex object I also run ShowEdge naked edge and see a few needing sealing (two points with line between- magenta in my case), but also a few single magenta squares which despite megazoom still show as such. All looked fine until offset.
I had a planar elipse joinedged to the surrounding shape (looked like a lake in a quarry and offsetSrf totally messed up on that part of the model. Its why I used this shape to replace it before offsetSrf redone. it was a perfect shape from elipses, doesnt get more simple, then after offset I get this shape acting up ! Simple shapes messed up with JoinEdge.
