About Automatically Scaling a Sketch
When you create the first sketch in a model and then modify the value of a weak dimension for the first time, the sketch is automatically scaled in proportion to the modified dimension.
Auto scaling is enabled by default. To turn off auto scaling, click > > > , and then clear the Auto scale weak linear dimensions for the first sketch in the model check box.
Watch a video that demonstrates Auto Scale in Creo Sketcher.
There are some cases where auto scaling is not applied to the sketch, including the following:
• Auto scaling the sketch would change the shape of the sketch.
• There is a change to the outline of the model before the initial sketch is created.
• An analysis feature is applied to the model.
• The first time a weak dimension is modified, it is modified to have a negative value.
