Sometimes our linetypes may need to go beyond simple dashes and text. In many cases adding Symbols to a linetype can make it even more descriptive, especially, when a linetype needs to also specify a direction. In this lesson, we'll learn how to create complex linetypes that include symbols. On my layout, I've created some geometry that represents a custom linetype. Let me mentioned that I've drawn this geometry at the same size that I want the linetype to appear on the printed sheets. The first step in creating my linetype is to convert this arrow geometry into a shape.
I'll do that by selecting the Express Tools tab, I'll open the Tools panel, and I'll select Make Shape. I am going to save the shape file in the Exercise Files folder, inside the Chapter 8 directory. We'll call this file arrow. I will then give the shape itself the name. This is the name that AutoCAD will used to reference the geometry. I'll type arrow and press Enter. Then, I can enter a resolution. The higher the number the closer your shape will match the original line work. 128 is usually fine. So I am going to press Enter.
I will then choose an insertion point. I'm going to select the Midpoint Between 2 Points and I'll select the endpoint of this line and the endpoint of this line. Finally, I'll select the objects that make up my shape and I'll press Enter. Now that my shape is being created I am going to select this geometry and I'll press Delete and then I'll replace it with the shape. I'll do that by typing shape and I'll press Enter. The shape name is arrow. I will insert this at the Midpoint Between 2 Points. I'll select the endpoint here and the endpoint here and then I'll press Enter to accept the default Height and Rotation Angle. As you can see, shapes are inserted just like a block.
Now let's convert this geometry into a new linetype. I am going to open the Tools panel again, and I'll select Make Linetype. I'll save the linetype file inside the Exercise Files folder, inside the Chapter 8 directory and I'll call this file mycustom2. If you've worked through the previous lesson with me, feel free to add the code to the previous LIN file. My linetype name is going to be as STM. The Description will be Storm Sewer.
The Startpoint of my linetype will be the endpoint down here. The point at which my linetype repeats will be the endpoint here. I will then select my geometry and press Enter. Let's back up a little and I am going to create a line segment. I will then select the line and I'll assign it the new linetype. Now that you know how to create complex linetypes, don't stop here. Try mixing dashes, text and symbols in the same linetype. With a little experimentation you can create nearly any linetype you can imagine.
