About Scaling Sketch Geometry
You can scale the sketch geometry within an active sketch. You can also scale the sketch geometry when you paste a copied geometry or import existing geometry within an active sketch.
Consider the following points when you scale sketch geometry:
You can use the translation handle as the scaling reference.
You can select a reference to define the scaling reference. This reference can be a sketch point, sketch coordinate system, endpoint of geometry, construction, or reference geometry.
The scale factor appears along with the scale handle. The scale factor lists the scaling with respect to the size of the original geometry.
The scale factor dimension is a temporary dimension. You can select this dimension and specify the scale factor or specify a value in the Scale collector of the Rotate Resize tab.
