Kevin,

Thanks for posting up this information. I have no experience with anything but Draw, so I can't offer recommendations for other software.

Draw is also compatible with using a tablets. I've got a Bamboo tablet, but really do not use it much. I can do pretty much anything that I want using the mouse.

Draw has some really good tutorials. But, they cover a lot of stuff that is not necessary for knife designing. By the time that I got through a tutorial, I couldn't remember the parts that would be useful to me. Most of what I have learned about using Draw is from just working with it and looking at the Help Menu. Still, I've spent a lot of hours frustrated because I couldn't remember how to do something that I had done before. I hope that this tutorial thread will be simple enough that it will teach readers the steps necessary for designing knives.

I intend to keep adding to this thread for a long time. I have learned so much about using Draw that I could probably keep posting to this thread for a year. I've got some really cool things to show.

I'll get back to the folder design soon. The next step is designing the spring.

Time to add the spring.

With the Pick Tool, select the main blade (not the rotated copy). This will direct the Pen Tool to snap the spring's line to the Nodes on the blade.

Using the Pen Tool, move the cursor to the Node at the top of the blade's spring notch, at the spine. When the work "node' appears, click there. Move the cursor straight down to the bottom of the spring notch and click when aligned with the Node at the corner of the notch. Move the cursor to the right, to a point past the blade's kick. Hold the Shift Key to force the line to be straight and click there. Move the Cursor to a point on the blade handle, just past the point of the rotated blade and double-click to end the line. I have changed the color of the spring's line to red, so it is easier to see in this conglomeration of lines.

Posted Image

Using the Shape Tool, click the Node at the end of the spring line, then convert this line to a curve line by clicking the Convert Line to Curve icon on the tool bar.

Posted Image

Then, shape the spring as you wish.

Posted Image

More Nodes can be added and used to define the shape of the spring.

Posted Image

From the Flowchart Shapes menu, select the circle with crosshairs and size it to whatever size pins that will be used in the handle of the knife. Drag the shape to position on the knife pattern.

Posted Image

An easy way to make duplicates is to use a short-cut key. With the circle-crosshair selected, hold down the "control" key and hit the "D" key on the keyboard to create a duplicate.

Make duplicates of the circle-crosshair as you need and drag them into position.

Posted Image

Make another circle-crosshair and size it to the pivot pin diameter. Drag it to snap into position at the blade's pivot point.

Posted Image

Use the Pick Tool to drag a selection marquee around the handle area. Use the Control + D keys to create a duplicate of the handle.

Posted Image

Click on a blank area of the sheet to deselect the duplicated handle. Use the Pick Tool to select the blade in the duplicated handle, then delete it.

Drag a selection marquee around the duplicated handle and make another duplicate of it.

Posted Image

On one of the duplicate handles, use the Pick Tool to select the spring line and delete it. Here is your liner pattern. Sorry, I messed up the images. The top shape is the liner pattern.

On the other duplicate, delete the circle-crosshair for the blade pivot. This duplicate will become the spring pattern.

Posted Image

Using the Pick tool, hold down the Shift key and click on the handle and spring shapes to select them; but not the circle-crosshairs. On the Arrange pull down menu, select Combine. Then select Arrange- Weld. This will change the two shapes into a single object (combine) with Nodes at their intersections (welded).

Using the Shape tool, select the Node at the intersection of the handle and spring bottom. Click the Break Curve icon ,on the tool bar. Zoom in and find the Node that is at the end of the handle's bottom line, running towards the front of the knife. There will be three arrows there. One of them is the Node that you are looking for.

Posted Image

Double click on this Node to delete it, along with the line segment.

Posted Image

Continue deleting Nodes and line segments until you reach the front of the spring.

Posted Image

Here's your spring pattern.

Posted Image

Make a duplicate of the handle shape and add lines for bolsters. Make a duplicate of your blade. Here is all of the patterns that you need to build this knife.

I get emails from Buy.com and saw this sale ($219) on Corel Draw.

I never could get my Etch-a Sketch to network with my printer. :lol:

I need to get back to this thread and add more to it. There is still a lot of stuff I want to demonstrate. Just a little busy right now finishing knives for the AKA Show.

Time to add some more to this thread. More details can be added to this drawing. I'll get into colorizing the drawings for sending to a knife customer.

Use the Pen tool to add a line for a false edge.

Posted Image

Use the Shape Tool to convert the line to a curve and then pull the line down with the Shape Tool to create the false edge.

Posted Image

Use the Ellipse Tool to make a flattened hemisphere for a nail nick. Creating a portion of a circle is done by using the Pie Shape controls on the toolbar (red circle).

Posted Image

The nail nick can be filled in with color by using the Smart Fill Tool (red arrow). The Smart Fill Tool will fill any area that is completely enclosed. Click inside the nail nick to fill it with black.

Using the Fill Tool (red arrow), choose Fountain Fill. On the Fountain Fill Menu, you can choose the type of fill pattern, the colors that will be used to create the fill and the amount of the fill colors that will be applied. In the small square window at the top right of this menu, there should be a cross-hairs (but, not seen in this image). You can move the cross-hairs to change the direction of the fill colors. After making your choices on this menu, click on the knife blade to color it.

Posted Image

Going back to the Smart Fill Tool, use the pull-down color chart to select a darker shade of gray.

Posted Image

Click inside the false edge to color it.

Posted Image

Using the Smart Fill Tool, add color to the bolster areas.

Posted Image

Click on one of the bolsters and then use the Fountain Full to change the solid color to a fountain fill. Also do the other bolster with a fountain fill.

Posted Image

In the next post, I will show how to create a pattern fill from a photograph. I will use the handle material from a photo of another knife to fill the handle area of this folder.

You can create a Pattern Fill from a photograph to fill areas of a drawing. One way to do this is to import an image into your drawing. Using the File drop-down menu, select Import.

Posted Image

This will bring up a menu for you to select the image that you wish to import.

Posted Image

Click on the screen and drag the cursor to import the image and size it to approximately the size of the handle in the folder drawing. Using my photo editing software, I have created an image from the jig bone handle of a folder that I had previously built

Posted Image

Click on the Tools menu, Create, then click Pattern Fill. A pop-up menu will appear; click Full Color.

Posted Image

Posted Image

A cross-hair will appear on the screen, drag the cross-hairs to create a marquee around the image.

Posted Image

A pop-up window will appear; click OK. This will cause another pop-up window to appear, where you will name the new pattern fill and save it in the Patterns Folder.

Posted Image

Use the Pick Tool to select your drawing. Then, select the Interactive Fill Tool (red arrow).

On the Tool Bar (red circle), select Full Color Pattern. Find your new Pattern Fill in the drop-down menu and select it.

Posted Image

Your Pattern Fill will be added to the drawing. It is applied with control handles to adjust the size and angle of the Pattern on the drawing. Adjust the Pattern Fill until it looks good.

Posted Image

Use the Pick Tool to drag a marquee around the drawing and Group the elements together.

Posted Image

Drag your blade into position with the handle. I have filled the blade with a ladder pattern damascus Fill.

Posted Image

If when you drag your blade into position you have this issue where it is placed on top of the handle, you will need to change the order of the drawings on the page.

Posted Image

With the blade drawing selected, pull down the Arrange menu, select Order, then To Back of Page. This will move the blade drawing behind the handle drawing.

Posted Image

You can turn this colorized drawing, or anything that you create in Draw, into a PDF file. A PDF file is a good format to use to send your images to a customer. Almost everyone can open a PDF file and a PDF file is small, so it emails easily. Go to the File menu, select Publish to PDF.

Posted Image

This will display a menu for you to name your PDF file and select the folder where you wish it to be stored.

Steve

For anyone with access with Adobe, I tried following your tutorial with laid-up and it works fairly well in Illustrator. The differences are minor and easily addressed using the Adobe help for Draw users.

Now if I could only make a blade that looks like the drawings....
