Assembly Layout Sketch

You can design an assembly from the top-down using layout sketches. You can construct one or more sketches showing where each assembly component belongs. Then, you can create and modify the design before you create any parts. In addition, you can use the layout sketch to make changes in the assembly at any time.

The major advantage of designing an assembly using a layout sketch is that if you change the layout sketch, the assembly and its parts are automatically updated. You can make changes quickly, and in one place.

To use an assembly layout sketch, do the following:

  • Create a layout sketch in the assembly in which various sketch entities represent parts in the assembly. Indicate a tentative location for each component, capturing the overall design intent.
  • Reference the geometry in the layout sketch when you create each component. Use the layout sketch to define the component size, shape, and location within the assembly; check that each part references the layout sketch.

Creating a Layout-based Assembly Design

In layout-based assembly design, you can switch back and forth between top-down and bottom-up design methods. You can create, edit, and delete parts and blocks at any point in the design cycle without any history-based restrictions. This is particularly useful during the conceptual design process, when you frequently experiment with and make changes to the assembly structure and components.

To create a layout:

  1. Open a new assembly.
  2. In the Begin Assembly PropertyManager, click Create Layout.
    A 3D sketch opens, and Layout appears in the FeatureManager design tree.
  3. Create sketch entities and group related entities into blocks.
  4. Close the blocks and the sketch.
    You can create a layout in an existing assembly by clicking Create Layout (Layout Tools toolbar).
