I'm trying to thicken surface after loft, but it does not allow me to make the 2.2mm thick, what do I do wrong?
hope you can help.
The issue comes in with your loft. You need to add guide curves in order to tell the software which vertices connect where, otherwise it will do it for you causing strange curvature and weird asymmetric faces that may have harsh transitions between one another. Take a look at the attached part and try to follow some of the choices I made when determining how to get a loft to complete. Keep in mind this is just one way to do it. I don't know what your part needs to look like and I don't know your intent so some additional changes may be needed on your part.
Additionally, I had to go back and fully define your base sketches. This is very important to do so that symmetry is locked and the profile will not change unless you intentionally change a relation or dimension.
Guide Curves to fully define loft: (Some of these may be redundant but they were quick to add)
I'm only having a guess here but I think it's because of the points you have created that then flare out, almost like creases.
And this occurs on both sides of the large end.
Thickening is temperamental when it comes sharp points and crease lines.
You can do it, but you must fix some issues after...
I'm guessing that you thickened externally Ruben? Whereas I was trying to thicken internally lol.
Perhaps Bruno can clarify which way he wants to thicken to start with. I only assumed he wanted to go internally because of his solid, whereby as you can see when you go externally like you have, the solid now looks out of place.......... guessing.
Anyhow, I could only get it to thicken internally to a max of 1mm without changing any geometry.
LoL maybe you're wright pal....I will try to make it as you said (thicken internally).....Let me see....
With thicken internally I can't make it....maybe selecting some faces, trim and lofting but it needs a little more time....
Dave Bear I modify the sketchs and give the offset inside and rebuild the lofted surface, then after give the thickness outside have a look
Thx i dident know about add guide curves, that helped alot.
Thx for all youre help, alos to the others how replied.
