Change Sketch Orientation

Hi everyone and happy new year!!

I have a problem, which will surely seem bogus to you but I'm freaking out!

I explain myself, I make a sketch on a surface (so far so good). I change the inclination of my surface (I don't delete it, just I go from 45° inclination to 90° vertical). And then, stupor!! Already my sketch has lost its reference (no problem, I just have to click my face again) but above all my sketch rotates 90° to the right (or left). On CATIA you can choose the orientation of your sketches (even during an update), paradise in short. I'm sure that on SW there is also this possibility (well I hope mostly).

If anyone has the solution, can please let me know?

Thank you in advance for your answers

Hello @Floris.Morales

Happy to see you again after such a long absence from the forum :smiley:

Can you post your piece because for the surface it's a little more complicated than sketches on a plan.

With your part, our surface experts will be able to give you the right solution for sure.

Kind regards

Hello Zozo,

It's simple volume. Indeed I expressed myself badly, replace "surface" with "face"

Thank you

Hello
Do you have an image, it's always more telling :slight_smile:
Have you tried to make your sketch via a plane on your surface and not directly on the surface?
Because once your plan is referenced from your sketch you can change the normal of your plan. You right-click on your map and you have a " Normal inversion" icon:

Otherwise to edit your sketch easily you have tools that allow you to rotate and move your sketch. When editing your sketch you go to Tools/Sketch Tools and you have Move or Rotate:

Hello

Your case is easy to reproduce and this is due to the fact that your sketch is not constrained with respect to two axes or dimensions from the edges.

On the other hand, I can't reproduce the inversion, in other words, the sketch wanders around on the front but remains oriented correctly.

Kind regards
PS: Please post your piece or at least a partial view with a view of the creation tree

Hello
In order not to complicate my life, I make a block of it and from there I can do what I want with it.
may the force be with you.

Hello @OBI_WAN

I think that the block doesn't change anything if it is not blocked on two edges, axes, planes.
If, however, my example is correct, the sketch is not distorted, it only moves!

Tell me if I'm talking nonsense or equivalent :grinning:

Kind regards

Hello
When a sketch is created on a face, it automatically adds a new origin and relative x-y-axes, which are the projections of the origin and axes of the absolute coordinate system.
When the orientation of the face changes, its datum system updates. If the orientation changes from 45 to 90°, it changes quadrant so horizontal/vertical can be reversed according to the necessary projection.
If the sketch is not constrained to the face then it will follow the position and orientation of its relative coordinate system.
So the solution given above is the only one. Completely constrain the sketch in relation to the face. Avoid H/V constraints.

Wow! So hats off! That's an explanation

  BAM !

Re-BAM

When I read this I feel totally igniard (but I don't tell anyone :smile: )

Bravo Soring doesn't hesitate to make us more like that! :blush:

Kind regards
