two surface which should be parallel/perpendicular are not. (blend issue)

hrezaeiEZXKZ · ‎10-06-2022

okay, this is driving me crazy, for some reason I am having a weird issue. I took a few pictures to show it. I don't know why it is happening but a few surfaces that should blend together are not because of this bug. I don't know how to replicate the issue but if there is a way to solve it I would appreciate it.

as you can see I have 3 surfaces that should all be either parallel or perpendicular but one is not, as can be seen in my pictures. why is this happening ??? this is resulting in a weird blend issue which I don't know how to solve.

thanks

It would really help if you would attach your model. Hard to tell much from your pictures as to the reason. If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

@jhackney1972 here you go. not sure how it will open up because it has other references in it but I did attach it.

the issue happen more or less in the end of setup5. the extrude30 is the one that should blend but makes a new surface for some reason.

I spent almost 5-6 hours to figure this out and couldn't.

I am wondering if you attached the wrong assembly. I cannot find an area that "totally" resembles your original screen captures. If this is the correct file, then all the angles I can measure that are close to the location of your screen captures, all measure square or planar.

you got the right model. i am not sure why but sometimes does measure 90 sometimes doesn't. look at my screencast. either way, I can not measure the distance to that surface even though it says the angle is zero. since I can not measure the distance it only means those two surfaces are not parallel. again look at my screencast. any idea?

https://autode.sk/3CAJXlI I embedded it but I don't think it showed. here the link never posted screen cast before

Your model has a lot of timeline errors and feature suppresses, which I do not understand, but these may be giving you so measurement issues. On the surfaces, where you cannot measure between them, I did a little test in a new sketch created from them. The results are shown in the video. I really do not have any better input for you except maybe model this again, keep your timeline free from errors and use a method that does not require suppression of features. You may be chasing ghosts.

Not really, my question never got answered so I can't choose that as answer. I believe it is a bug in fusion or something which I am not sure what. I knew how to measure those distances the solution represented above more or less suggested redoing everything since they suspect I might be chasing ghosts which to a degree I agree with but I don't think suppressed futures with warnings are causing it. anyhow the problem never got solved in that specific model.
