problems with surface profile in freeform

[[st...]]

hi, sorry for the novice question. but i'm very new to curves and freeform

let me try and explain as simple as possible.

i'm programing on a 3D model

i used alot of 3d curves and spacepoint
i need to measure surface profile on certain places.

my idea was : "freeform surface" ---- "recall feature points" ----- select the spacepoints and/or curves i need

now this is where i start scratching my head ; the "actual's" on that freeform come out anywhere from 0.0007 to 2.5mm, where they should be 0.0000....

if i recreate the freeform and measure everything within it , it does come out 0.000

does freeform not preform correctly using recall feature points?

Working on planner or real part?

planner

I think from what i've read on forum, that planner gives some results - not just ZERO. But 2,5 is strange.

Are you working with model? I have never recalulated curve to FF - I just recalled points and selected face on model if needed.
How looks deviations when you turn on graphical evaluation? It should show you where is that big deviation.

again, excuse my stupidity 😃





the model is the "perfect" shape so every surface profile i measure should be 0.0000 right?

If you are simulating measuring then NO you will experience some data NOT zeroes.
If you don't have measured data, then your results will be zeroes.
