why do we do sketch trace in CATIA?
As i suspected. OK then, thanks again for this great tutorial and for your help
Hello Marco. As you said that you want to create a other part within the same part you can create a body and do it. Bcoz if you are creating a other part in the same thing then it wont be a multi part type. So every time you have to create a new part.
to complete my previous comment. each time i finish a part, when applying the reference image again i might not define the limits of the image correctly.
Hi, thanks for the tutorial. i have a question. i have a picture of an aircratf turbine as a reference. it is a cut along the longitudinal axis. i want to make different parts of every components i can. do i have to follow the procedure in this tutorial for every part i am drawing, or is it possible to keep the image as reference and start working in a new part without exiting the current part. did i explained my self clearly? thanks again for this great tutorial
