How to scale a sketch?

александр_боровенский

You need to scale an object from splines. Need to make it smaller. How?

john_mcclary

If you only have one dimension in your sketch. Then you can change that dimension and everything in the sketch will scale

You need to make sure that you do not have any constraints attached to other sketches or parts

Does not work...

john_mcclary

I see a lot of black lines. That means they are fully constrained. That is what is holding you back. 

Instead, concider extruding the sketch and scaling the part. 

If you really want the sketch to scale, you can break the constraints by using transform in the sketch. Then slap a dimension somewhere and edit the dimension

Squeezed out, but how to scale?

Once its a solid or a sheet you can use the Transform feature to scale it:

If you don't want to extrude, you can use Offset Surface with the offset distance set to 0 to just make the sketch into a surface, and then scale that surface using the Transform feature:

Great tips — good stuff to know

SCALING THE SKETCH

MAYBE the below info will help

With regard to the sketch shown in the GIF, there were 2 FIX constraints that I had to delete, on top of deleting 2 of the 3 dimensions, which left me 1 dimension that I was able to change and scale up the sketch

Colleagues! Many thanks for the help! Good luck!
