![]() ![]() ![]() If you want to add a relationship between two lines, select them and you’ll see an angular dimension pop into place. ![]() That means the system has generated that value – double click it and you can add your value. You’ll see the double tilde symbol next to the value. You’ll see that there’s a dimension popped into place. Want to add a dimension to a line? Click the line. Over the years, a parametric element has also been added, allowing you to build in relationships between dimensions to drive the adaption of those sketches, both in reference to their own dimensions, but also across features in parts or, indeed, between parts or assemblies.Ī pretty intuitive sketching and constraining workflow: Create your sketch entities as per normal, infer some of the relationships as you would in a traditional sketcher, then start to add in dimensions and such to nail things down. You create your lines, circles and arcs to create the shape, then add dimensions to dial in the exact form you want.Īlong the way, there have been key additions, such as constraints and relationships – whether added manually or inferred when sketching. While other methods (surface manipulation, curve networks, primitives and Boolean operations) exist, for the majority, using predominately history and feature-based, creating a 2D sketch is the starting point for almost every all modelling operations.Ĭonsider how most sketchers work and have worked for years (if not decades): They’re essentially mimicking the technical drawing process. Siemens Digital Industries Software has just updated its NX product with a brand-new sketcher and it’s worth taking a closer look at.Īnd trust me, it’s not often that we all get excited about a new sketching tool, is it? After all, 2D sketch has been a core part of almost every 3D design system for decades. ![]()
