FreeCAD Workflow - Model Reliability and the The Art of Overdoing It (#2)

Video Description

In this video, we explore FreeCAD's new Variable Set feature to create stable and reliable models without relying on spreadsheets. We’ll walk through setting up Variable Sets, using expressions for dimensions, and integrating best practices to keep your designs adaptable and consistent. What You’ll Learn: - How to create and use Variable Sets in FreeCAD. - Linking sketches and models to variables for better control. - Techniques to avoid common issues like the topological naming problem. - Setting up reliable dimensioning and constraints for sketches. ------------------------------------------------------------------------ 00:00 Introduction 00:12 Disclaimers 00:33 Use when necessary 01:01 Top-Down Modeling 01:20 Bottom-Up Modeling 01:53 Master Modeling 02:37 Modeling start 03:09 New VarSet feature 04:28 Using VarSet in Sketch 05:01 Inline creation of Variables 06:06 Using Datum Planes 06:41 Datum Plane dynamic update demonstration 07:25 Carbon Copy feature 08:32 Expressions in VarSet 11:43 Dimensioning from Origin 12:31 Why Over DO it? 13:18 Demonstrating Topological Naming Problem 14:08 Sketch TNP jump 14:22 Preventing TNP 15:39 Reference (Driven) Dimensions 16:13 Demonstrating reliability 24:10 Sketch Symmetry Tool with Constraints 24:57 Reverse option 26:40 Moving Bodies and enabling dynamic updates ------------------------------------------------------------------------
