SOLIDWORKS Fully Defined Sketch
  • SOLIDWORKS Fully Defined Sketch

    In this post, we will look at how to use the Fully Define Sketch tool and how it will help when it comes to adding missing dimensions or relations to a sketch entity and also to dimension the sketches from the imported geometry after using Featureworks. Also, we can import the Autocad(DXF or DWG) files as a sketch and automatically add dimension using this tool.

    Sketching in SOLIDWORKS is always easier with lots of shortcuts. An important thing to note when it comes to sketching is to add all necessary dimensions and relations and the best practice for sketching is to make the sketch Fully Defined.

    Why is the so important to make the sketch fully defined?

    When making design changes to the 3D Model or when editing the existing model under defined sketches, the design will get affected and misaligned which lead to errors and warnings based the parent/child dependency between the features. To avoid this, it is always good to make the sketches fully defined.

    How to know that the sketch is fully defined?

    If all the dimensions and relations are added then the fully defined sketch entities will be in black colour (default colour settings for fully defined) and sketch entity cannot be moved also in the bottom right corner at the status bar it will show fully defined.

    Fully Defined Sketch Property Manager:

    • Apply dimensions and relations calculated by the SOLIDWORKS application to fully define sketches or selected sketch entities.
    • To open the Fully Define Sketch PropertyManager, do one of the following:
    1. Edit a sketch, and click Fully Define Sketch  (Dimensions/Relations toolbar) or Tools > Dimensions > Fully Define Sketch.
    2. Import a sketch from a .DXF or .DWG file drawing, and click Tools > Dimensions > Fully Define Sketch.
    • Entities to Fully Define:
    All entities in sketch Fully defines the sketch by applying combinations of relations and dimensions.
    Selected entities Applies relations and dimensions only to specific sketch entities that you select for Entities to Fully Define.
    Calculate Analyzes the sketch and generates the appropriate relations and dimensions.
