I can not cut surface using projected curves or maybe I did it wrong, just I need help please. I attached a image about my problem with this issue.
Thanks in advance.
Why don’t upload your file?
Okay, here is the model…
thank you so much

Hi Ricky the lower curve is open - there are a few tiny fragments - really tiny - near the seam of the cylinder. If you window around your curves and Join, the result should work for Split/Trim.
Hi Pascal, Thank you so much! you right 100%, the curves were “open”. I applied one tool in curves tab options for close them and work fine!!
Thanks a lot!
I will try to finish this model… I something wrong I will ask for help.
Thank you Costel & Pascal
Have a nice day
Hi Ricky - I would Join the existing curves rather than CloseCrv if that is what you did - it may make little difference in this case because the gap is so small, but it will change the curve in a different way (close with a staight line or force the ends together, depending on how far apart the ends are) than Joining the bits that actually follow the path you want.
Hi Pascal, yes I tried to join them, but the empty space between lines are very very small, and was very difficult draw lines to join them, so I decided to closed them, was more easy. And here is the result.
By simply changing the Absolute Tolerance from 0.001 mm to 0.1 mm, even the second curve (the “open” one) was able to split the surface just fine.
I noticed in this forum that many problems go away just by increasing the tolerances in your model. For example, when you are building a boat/yacht and then use micron tolerances you are bound to do way too much unnecessary work.
If your model is just a work of art, then your 0.1 tolerance will not hurt anyone. If on the other hand your model is some sort of a cam in a high precision mechanism, then 0.001 precision is a must and you need to put in the time and close that curve.
Hi Costel!, Very good information, I never thought about this parameter, it would have avoided a lot of work.
Thank you very much, I learn a lot in this forum…
Be cautious messing with loosening tolerances in the modeling process - you can end up with more work, depending on what the and use of the model is.
