Hello
"The positioned sketches would make it possible to avoid external references."
However, in this regard, I have a point that I would like to understand better.
Are these "external references" the same as those we have, if, for example, we are working on one part and in its construction, we want to use a geometric element (wireframe or surface) or another parameter on the other hand?
Would it be possible to make an example with a positioned sketch and a without to illustrate this economy of external references?
Thank you in advance for your help.
Hello, the need for external references is related to the project and in no way to the use of sketches, positioned or not.
There is no economy, if the parameterization imposes a link to another part, or element of the part, the external reference (parent) will have to be created, whether with a sliding or positioned sketch.
The use of positioned sketching makes it easy to reuse the sketch in another environment (copy/paste) or optimized copy.
Because we control the flat support, the origin and the orientation.
If a positioned sketch contains external references , it is obvious that in the new environment these external references will have to be redefined or isolated .
ok thank you for your info.
Does the "sliding" sketch in the "positioned sketch" window actually correspond to the classic or basic sketch?
Yes!
You have to keep in mind that under CATIA it is exceptional to have to destroy what you have done, practically everything is redefinable.
We transform a sliding sketch into a positioned, and vice versa.
