The Fully Define Sketch tool in\u00a0SOLIDWORKS\u00a0<\/a>is<\/span> a great way to fully define a sketch by automatically creating dimensions and relations. It can be applied to selected sketch entities or the entire sketch, but should be used with caution.<\/p>\n

While Fully Define Sketch is a powerful tool for locking down geometry, it is important to understand how it affects design intent.<\/p>\n

What is the Fully Define Sketch Tool in SOLIDWORKS<\/h2>\n

Fully Define Sketch calculates dimensions and relations in SOLIDWORKS needed to fully define a sketch at any point. A fully defined sketch has no freedom to move or rotate.<\/p>\n

SOLIDWORKS helps you identify underdefined components by highlighting them in blue. Ensure that you look for the points on a line or arc, as they may not be defined despite the arc or line indicating definition.<\/p>\n

\"Using

The Fully Define Sketch PropertyManager can be opened by clicking the Fully Define Sketch command from the CommandManager. You can choose entities to fully define, relations, and dimensions to help lock down a floating sketch.<\/p>\n

It is best practice to include some relations and dimensions before using the Fully Define Sketch tool. Be cautious when using Fully Define Sketch because it does not always produce dimensioning that aligns with your design intent.<\/p>\n

Dimensions and Relations Options<\/h4>\n

The Fully Define Sketch PropertyManager includes sections and dropdowns to specify the relations and dimensions you want to include.<\/p>\n

\"Dimension

Under the Relations section, you can select which relations are allowed to be applied. You may choose to select all or individually pick the ones you want.<\/p>\n
