We've been hearing from our customers a lot recently about DraftSight, a 2D CAD design tool that is available for free from Dassault Systèmes. It has all the features you need to get started with creating CAD drawings for Big Blue Saw. It's available to download and use for free from the Dassault website for use with Windows, Linux, and Macintosh.
Here is a very brief, very basic tutorial on using DraftSight to create drawings for Big Blue Saw.
Start DraftSight from the Start Menu, desktop icon, or however it works on your system. You'll see the main DraftSight window as shown below.
The left hand toolbar shows a variety of drawing tools. In this tutorial, we'll be creating a simple rectangle. Click on the rectangle tool.
Click in the drawing area to define one corner of the rectangle.
Then move the mouse and click on the diagonally opposite corner to define the other corner of the rectangle.
You now have a CAD drawing of a rectangle.
Choose "File | Save As" from the menu.
Enter the file name in the appropriate box. Next, choose the file type from the drop down list. Here we're choosing "R2013 ASCII Drawing (*.dxf)". You want to pick one of the "ASCII DXF" file types for use with Big Blue Saw.
Click the "Save" button to complete saving the file. Congratulations! You now have your first DraftSight CAD drawing ready to use with Big Blue Saw's online quoting system.
Once you use Big Blue Saw to turn your rectangle design into a real part made out of metal or plastic, you could use it as a spacer, shim, bookmark, backing plate, or divider. It's not much to look at, but now that you've gotten started, you can play around with DraftSight and see its tools for making other shapes.

Announcing a brand new material: carbon fiber.
Many of our customers have been asking for this strong, lightweight material, and, after much experimentation, we now have a waterjet cutting process capable of creating great looking carbon fiber parts.
Our carbon fiber is stiff and has a shiny finish with a plain weave. In addition to the outstanding mechnical properties of the carbon fiber sheet, it looks gorgeous as well. The picture above doesn't really do it justice, as the appearance changes as the light catches it from different angles. So you can use carbon fiber to give your control panels and signs an ultra-modern, high-tech look.
I also expect we will see many orders for this material for small flying machines like drone copters, fighting robots, RC cars, handheld gadgets, and anywhere light weight and high strength are a must.
Keep in mind that due to the unusual nature of this material, there are a few small quirk relating to part geometry. First, we're offering parts up to 11.75 inches square in the online quoting system. Contact us by e-mail at info@bigbluesaw.com if you need something bigger. Next, round holes down to 0.063 inches (about 1.5 mm) are OK; we'll be drilling those out instead of waterjet cutting them. Finally, internal holes that are NOT round must have a section at least 0.25 inches wide somewhere in them so we can drill a pilot hole for the waterjet. The online quoting system doesn't check for the last condition, so if you order a design that has a tiny internal slot, let's say, we'll contact you for possibilities on how the design must be changed, like adding a larger attached hole.
This is part 2/2 in a series of guest posts from Jay Doscher.
In the previous article we worked on designing a part on the computer. We sketched out the part on graph paper, designed it in Visio, then printed it out to make sure it fit on our project chassis. It will take a couple weeks or so to get the parts in the mail, and we're going to pick up the project after getting the parts back. You can see the paper print out below where we printed it out and cut it out on paper from last time.This guest post is from Jay Doscher. Part 2 of this series will appear next Friday.
You can save big on custom aluminum parts with our sale that runs from Wednesday, October 29 through Friday, October 31. During the sale, all orders placed online for aluminum 6061 in 0.125" (1/8" or 3.2 mm) thickness will receive a quantity discount, no matter how small the order.
For example, our control panel example part will cost just $25.70 in quantity 1 during the sale, a savings of 72%. Our butterfly example part will cost just $9.20 in quantity 1, a savings of 90%!
