Could we scale a 2D sketch in CATIA?

Answer 1

Yep, and it's not too hard either!

1. Open up your 2d sketch
2. If you want to scale the entire sketch, highlight the entire sketch, and if you only want to scale parts of your sketch, then only highlight those lines.
3. Go to Insert > Operations > Transformations > Scale
4. Now a pop-up should appear asking for the value you would like to scale it the sketch. (i.e. if you want to double the size of the sketch, value=2)
5. You will now be prompted to choose a point. This point will be the part of the sketch that won't move and will retain its position. (i.e. if you want the bottom corner of your sketch to remain planted and the rest of your sketch to be scaled, go ahead and choose the bottom-most corner of your sketch)

That's it! You're done!
