## SOLIDWORKS xDesign Lesson 11: Sketch Based and Applied Features

Through the years of teaching SOLIDWORKS, I tell my students important basics. 1. Select the correct sketch plane. 2. Keep the Base sketch simple. 3. Use constraints (geometric relations) before dimensions. 4. Keep features simple. Similar basics apply with SOLIDWORKS xDesign.

## SOLIDWORKS xDesign Lesson #10: Sketching, Constraints, Dimensions

Design intent manages the relationship between sketches in a feature, features in a part, and parts in an assembly. Students need to understand design intent in a sketch, using constraints and dimensions. Let’s start with a simple example using xDesign.

## Creating 3D Sketches in SolidWorks

This video shows the basics of using 3D sketches within your models.  3D Sketches are very useful when creating car chassis or anything where lines or curves cross through multiple planes.  They reduce the number of planes that will

Check out this video that shows where to find the tutorials in SolidWorks on DimXpert and TolAnalyst.  DimXpert allows you to create dimensions in your part documents that can be brought into your drawings faster which will save you time

## W16 Engine in SolidWorks

This is a model of the W16 Turbo engine used in the world’s fastest production car. I modeled it as a final project for the Introduction to CAD class. During the next few weeks I will walk you through the build, post the files and explain some of the math behind it. This post will cover the modeling of the basic piston:

Here is the link to the document that I used as a reference.

“The W Engine Concept – Self Study Program” VW of America, 2002, available here

See detailed explanation in the extended entry at the end of the post.

Thank you for reading about this build and stay tuned for the next post which will include the Conrod and the Piston-Rod-Rings Assembly.
