The simplest 3D CAD software tool to learn is Sketchup. We have a series of lessons below which will take you through Sketchup step-by-step. These lessons are designed to help the absolute beginner become adept at 3D design.
SKETCHUP LESSON 1: This lesson introduces you to the sketchup design pallet and shows how to design simple 2D objects being mindful of deliberately setting position and dimension when objects are created.
SKETCHUP LESSON 2: In this lesson we look at making our first simple 3D objects in sketchup. We make simple cubes to demonstrate different conceptual ways that Sketchup allows 3D elements to be created.
SKETCHUP LESSON 3: In this lesson we show how to print 3D designs on a 3D printer from Sketchup. Really a simple and straightforward process. It is simple and works great.
SKETCHUP LESSON 4: In this lesson we design and print a simple test 3D Widget. The purpose of this lesson is to continue to build our design skills. For this lesson you will need a nice set of digital calipers, which you can get HERE.
SKETCHUP LESSON 5: In this lesson we learn how to evaluate our physical design printed on a 3D printer using a pair of digital calipers. To do this lesson you will need a nice set of calipers, which you can get HERE.
SKETCHUP LESSON 6: In this lesson we learn about the concept of Design Rules, and come up with a simple test device to determine some important design rules for our 3D printer.
SKETCHUP LESSON 7: This lesson shows the importance of thinking about tolerances when you are designing. In this lesson we design and build a simple test structure that will help us understand tolerance for slip or press fits.
SKETCHUP LESSON 8: In this lesson we show you how to think like a mechanical designer and to keep design rules and tolerances in mind as you design.
SKETCHUP LESSON 9: In this lesson we show how to design more complicated devices requiring extrusion in orthogonal planes.
SKETCHUP LESSON 10: In this lesson we learn how to go back and change dimensions if necessary.
SKETCHUP LESSON 11: In this lesson we learn how to use the Follow Me tool to allow more comlplex 3D designs in Sketchup.
SKETCHUP LESSON 12: In this lesson we learn how to use the Rotate Tool to adjust position of 3D Objects.
SKETCHUP LESSON 13: In this lesson we show how we hit the wall on more complex 3D designs.
REVIEW OF THE RAISE3D PRINTER: This lesson shares my experience so far with the Raise3D printer. In my mind, the best printer for the home or education market available today.
