Intersection and Silhouette Improvements Strengthen Sketcher

TopSolid 7’s sketcher has been improved and now provides the ability to create a silhouette profile at the solving level of the TopSolid sketcher.

Within this demonstration video, you will see dynamically the silhouette of the part we are working on based on the plane we’re in. For instance, I will demonstrate how to use our trimming plane option that allows you to choose the specific trimming point to calculate the silhouette profile from.

New geometries created by our adjustments can be trimmed away or modified, or of course, I can use the offset mode and set the offset dynamically.

Additionally, you will learn how we updated the intersect command to allow you to create an intersection based on the entire shape of the part versus having to specifically tell the system which face you wanted to intersect with as you had to do in the past.

Sketcher: Constraint based sketch vs. sketch operations

topsolid-tips-and-tricksWhen working with a 3d solid modeling solution like TopSolid, it is very important that you understand how its sketcher functions.  Most 3d modeling solutions have one way to create and work with sketches.  And that one way is supposed to fit every need you have.

The Problem

The problem with that notion is that your needs change all of the time.  The way you define geometry within a sketch needs to be completely flexible.  What do I mean? Sometimes you may want to create a simple sketch, while other times you may want to create a really intelligent sketch. Perhaps you want to create a sketch that allows you to apply operations to it that really allow you to capture your design intent more cleanly.  Thankfully for you, you use TopSolid and have the freedom to do both.

Understanding a sketcher

Let’s start by understanding what a sketcher is first.  A sketcher allows you to create wire-frame based geometry. In TopSolid there is a 2d Sketcher and a 3d Sketcher. For this discussion, we will be focusing on the 2d sketcher.

Different types of TopSolid sketcher constraints A 2d sketcher allows you to create wire-frame on a specific plane. The sketcher environment at the solving level, allows you to define the sketch using dimensional relationships as well as geometric relationships.  These are known as constraints.  In the image to the right, you will see a sample of a constrained sketch.  This image shows both dimensional and geometric constraints.
