WPONG Posted March 10, 2019 Share Posted March 10, 2019 Greets all. I'm trying to 'lengthen' a loft by shifting the last x-section sketch with the tri-ball. What I've tried: 1. Select the loft @ the intellishape level 2. Right click the "3" box for the 3rd x-section and "edit cross section" 3. Reorient the view to an isometric-ish view 4. Turn on Triball and drag x-section "3" to lengthen the loft. 5. Click "finish shape" ...and I get the pictured error Attached is the model, and a pic or two to explain. I'd appreciate advice on how to accomplish what I'm after... Along the way, I'd appreciate some clarification on the definitions / distinctions between "Guide Curve" "Center Line" "Profile Locator Curve" Thanks! --Will loft_lengthen.ics Quote Link to comment Share on other sites More sharing options...
WPONG Posted March 12, 2019 Author Share Posted March 12, 2019 Any thoughts, anyone? (I'm guessing I'm not the first to try and lengthen a loft...) A loft like this is the foundation for a part that I've built, so I'd rather not 'start over.' I'm open to other approaches to achieving my objective too, so I'm please share any suggestions or alternate approaches you may have... Thanks much, --Will Quote Link to comment Share on other sites More sharing options...
RCURD Posted March 12, 2019 Share Posted March 12, 2019 Hi Will, I had a play with your model. when the error box pops up click on yes and the loft reforms to the new position. Rick Quote Link to comment Share on other sites More sharing options...
tlehnhaeuser Posted March 12, 2019 Share Posted March 12, 2019 I thought you used a guide curve to follow, but it looks like you just selected 3 sections and loft, correct? Anyway switching to the ACIS kernel fixed it. t Quote Link to comment Share on other sites More sharing options...
WPONG Posted March 13, 2019 Author Share Posted March 13, 2019 Thanks Rick. Interesting, when I selected ok, I got another error "Loft cross-section contains invalid curves. Default shape will be used instead." I see tlehnhaeuser's suggestion of kernel switching, and maybe that is why you succeeded (I'll try switching kernels now...) --Will Quote Link to comment Share on other sites More sharing options...
WPONG Posted March 13, 2019 Author Share Posted March 13, 2019 Thanks Tom(I think it was?). That did the trick! 'Just not used to having this (nice!) option of switching, and frankly it didn't cross my mind! While I'm learning, have you any advice on which kernels are good for which types of issues? Much appreciated! --Will Quote Link to comment Share on other sites More sharing options...

Much appreciated! --Will 49273[/snapback] Hi Will, ACIS and PARASOLID advantages keep changing with each release, so its hard to nail down which is best for what since its like a horse race. That's why its great to have both because one release ACIS is best for things, then next release Parasolid is best. With IronCAD you always have access to the best :-) However, the general rules I conclude are: - ACIS is good with models that utlilize alot of "tangency" type geometry. - PARASOLID is good with models that require alot of complex Blending. - ACIS (Currently) better at handling Sheet metal type features. Hope this helps Tom Quote Link to comment Share on other sites More sharing options...
