Creating Complex Linetypes with AutoCAD Shapes: A Step-by-Step Guide

When it comes to creating custom linetypes in AutoCAD, one of the most powerful tools at your disposal is the Shape file. In this post, we'll explore how to use AutoCAD Shapes to create a complex linetype, and discuss some best practices for designing and using these shapes.

Getting Started with AutoCAD Shapes

To start creating an AutoCAD Shape, you'll need to select the objects you want to include in your shape. For this example, I'm going to choose where the two lines intersect. Once you've selected the objects, you'll be prompted for an insertion point, similar to when creating a Block.

Drawing Your Shape

Use AutoCAD Lines to draw the shape you want, remembering the rules outlined above: each line segment must be drawn in one of the 16 supported directions increments of 22.5 degrees, and lines may be no more than 15 units long. It's also important to keep your design simple, as complex shapes can be difficult to work with.

Creating a Shape File

To create a shape file, use the Make Shape tool (MKSHAPE command) found on the Tools panel of the Express Tools Ribbon tab. This will allow you to save your shape to an external file, which can then be referenced within a complex linetype.

Tips and Tricks for Working with Shapes

Keep in mind that AutoCAD LT users cannot create or insert shapes, but they can reference them within complex linetypes. Additionally, shapes are stored outside of the drawing, and are referenced from a file with a .shp extension.

It's also important to note that while you could write your own shape file within an application like Notepad, it's generally not recommended unless you're being paid by the hour! AutoCAD Shapes are similar to AutoCAD Blocks, but have several restrictions that are not otherwise present when creating blocks.

Creating complex linetypes with AutoCAD Shapes is a powerful tool for customizing your drawings. By following these steps and tips, you'll be able to create unique and useful shapes that can add value to your designs. Stay tuned for a future post where I'll discuss creating a complex linetype using the shape file I just created in this post.
