Session 10

1. Overview

This session centers on using SpaceClaim’s FILL Tool to efficiently tidy up, fix, and complete intricate geometries. You’ll discover techniques for eliminating features like fillets, chamfers, holes, and extrusions by growing adjacent surfaces to cover them seamlessly. The lesson explores function options such as Patch Fill, selection tips, and deciding when to use Tangent to All Sides for smooth transition. Additionally, Guide Curves are introduced to help manage surface continuity and predictability. By session’s end, you will know how to choose the best method for each scenario and apply the FILL operation confidently.

2. Learning Goals

The main objective is to apply the FILL Tool through practical examples, learning to remove unwanted details such as holes and protrusions from your CAD model.

A demonstration geometry illustrates several types of features—fillets, chamfers, holes, and extrusions—all attached to a single part. This setup is intended to give you hands-on experience executing the command for different situations.

3. Common Issues with the Fill Tool

Using the FILL Tool sometimes brings up specific challenges. In this lesson, you’ll address a frequent one: when a selected region has a misaligned or non-matching boundary, making it hard for the software to extend faces and achieve a proper fill. The tutorial provides figures and step-by-step solutions to these scenarios.

Another case studied is where the neighboring cylindrical faces differ in size, complicating the removal process. Here, you’ll learn best practices for splitting faces and making thoughtful selections, helping the software generate the desired surface.

4. Recap

In summary, you learned how to use the FILL command to remove holes, protrusions, fillets, and chamfers in SpaceClaim. The command extends surrounding faces to replace the selected region with a new surface. Problematic situations—like nonaligned bottoms or mismatched geometry—were solved by combining Split Face with strategic selection. Advanced options such as Patch Fill, Tangent to All Sides, and Guide Curves were explored to ensure high surface quality and predictable results.
