Custom Features are valuable tools that anyone with an Onshape account can create using FeatureScript. This Tech Tip will explore a handy Custom Feature: Fill Pattern.
Fill Pattern generates an array of faces within a target face while avoiding boundary edges. Fill Patterns are often more straightforward to create than multiple linear patterns. This feature is an efficient way of modeling periodic geometry, including perforations, filters, and textures.
Create the starting geometry and then follow this basic procedure to use Fill Pattern:
Add the Custom Feature to your Toolbar
Open the Fill Pattern document and click the "+" icon to add the custom feature to your toolbar.
Insert the Fill Pattern Feature
Click the Fill Pattern icon to activate the feature dialog. Next, select the seed geometry and a target face.
Select a linear edge, planar face, reference plane, or mate connector to define the pattern direction, and pick “square” or “hexagonal” to specify the shape.
Enter a distance to control the center-to-center spacing between instances. Optionally, enter a value to allow additional padding along boundary edges.
Advanced Fill Pattern Techniques
The Split tool helps isolate or exclude specific regions for patterning. First, define the area with a sketch and split the target face. Next, use the Fill Pattern feature as previously explained. As a final step, use the Delete Face tool to clean up unwanted edges.
