3D CAD - Extrude Boss & Cut Introduction - Table Napkin Holder

-
This is another tutorial in a Series on creating 3D Mechanical CAD Models using Alibre Design Xpress.

It's intent is to quickly cover two primary features:
- Extrude Boss (Make a Solid Object),
- Extrude Cut (Remove material from a solid object).

Within these two features you will learn finer points of different types, like Mid-plane, to Next, To Geometry, and uses of them.

You will also learn some simple sketching functions, like creation or application of:
- 2 point Rectangle,
- 3 point Rectangle,
- Circular Arc: Center, Start, End
- Elliptical Arc, Center, Major Axis, Minor Axis,
- Line, Reference line,
- B-spline.
- Symmetric Constraints,
- Linear Dimensions.

Note: - It is assumed you have already downloaded and installed Alibre Design Xpress, and know already how to start Xpress, if not, look at 3D CAD Non-Animated Tutorial - Feature #1 - Revolve - Basics - Step #1, in CAD Group at www.instructables.com

Proceed to Step # 1

Step 1 3D CAD - Table Napkin Holder - Set Workspace Grid

-
Ok - here we go!
First open a New Part Workspace
(as explained & shown in Step #1, described in Intro)

Then, activate the 2D Sketch mode, and Open Options from the Tools selection in the main menu,

Set Grid X & Y to 0.500", leave Z alone, Make sure display Grid and Snap to Grid are Checked.

Click 'OK' to close the Options Dialog and get ready to continue.
