The one exception is three angles, which will not define the size. A triangle is fully defined by 3 values, which can be any from the following list: side length, angle, height, area.

A way to show the difference is the construction of a triangle. The sketcher is different to traditional drawing tools.

The Sketcher is a tool to generate 2D-objects for usage in parts design.

5 Construction Lines - Step by Step Example.

4 Problematic combination of constraints.

In this tutorial you have learned enough about TechDraw to produce a drawing like this one (by NormandC). (if you still see 43.27, you may need to press the Recompute button or drag the dimension value a bit until it changes.) Our dimension should now read the correct value of 53.

In the dialog, move our dimension from the Available column to the Selected column.

Change to the 3D tab and select the Vertices at the ends of the front edge of the work piece.

Note the name of our faulty dimension in the Combo panel.

To get the right value, we need to link our dimension directly to the 3D model. This is because 'TopLeftFront' is an isometric projection, and our first drawing was an orthogonal (multiview) projection. This Tutorial will not use every feature and tool available within the TechDraw Workbench, but should use enough to give the user of this tutorial a basic foundation upon which to build their knowledge and skills.įrom the first part of this tutorial, we know that the work piece is 53 mm wide, but our new dimensions reads 43.27. We will create multiple Views of the part and add key dimensions. In this tutorial, you will be using the TechDraw Workbench to create a 2D drawings of the 3D part below. This tutorial will take user through the steps needed to produce technical drawings of the part from the Basic Part Design Tutorial.ĭownload the sample file from the Part Design tutorial. This tutorial is not a complete and comprehensive guide to the TechDraw Workbench and many of the tools and capabilities are not covered. This tutorial introduces the new user to some of the tools and techniques used in the Technical Drawing (TechDraw) Workbench.
