Just as it is today, linetypes are a core feature of proper drafting. I can still remember picking up that freshly pointed HB pencil and gliding it against my T-Square, while properly rolling it along the way to ensure an even line.<\/p>\n\n\n\n<p>The point is, we were the drafter, and we were responsible for knowing what to do, what type of line to use, and correctly applying that skill. A skill which in the world of CAD is generally rendered moot.<\/p>\n\n\n\n<p>But that\u2019s OK. This is one of those posts where, if your CAD department is set up correctly, most users will never need to load and manage linetypes. I know my users never did. So, while it is, as I said, a core feature, I\u2019ll go over the basics first, then jump into a cool tip that makes creating your own custom linetypes easy. This isn\u2019t called Tuesday <em>Tips<\/em> for nothing!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-a-linetypes-primer\">A Linetypes Primer<\/h2>\n\n\n\n<p>If you start a new drawing using the acad.dwt template file, you\u2019ll get three linetypes: ByLayer, ByBlock, and Continuous. To get more, you have to load them. Launch the Linetype Manager dialog by selecting the <em>Other<\/em> option in the Linetype pulldown menu in the Properties panel of the Home tab of the ribbon. Or type in LT. Your choice.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_1.png\" data-lbwps-width=\"942\" data-lbwps-height=\"448\" data-lbwps-srcsmall=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_1-300x143.png\"><img loading=\"lazy\" decoding=\"async\" width=\"942\" height=\"448\" src=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_1.png\" alt=\"Linetypes screenshot\" class=\"wp-image-16565\" srcset=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_1.png 942w, https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_1-300x143.png 300w, https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_1-768x365.png 768w\" sizes=\"auto, (max-width: 942px) 100vw, 942px\" \/><\/a><\/figure>\n\n\n\n<p>The next step is to click on the <em>Load<\/em> button. Doing so will display the Load or Reload dialog as shown below. Each type will have a name, a description that may better explain the linetype, and a graphic representation of what it looks like.<\/p>\n\n\n\n<p>Select the linetype you want, and click OK. It will now display in the Linetype Manager list, available for you to use in your current drawing. Again, you may have never actually done this, as it should have already been done for you. But now you know.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_2.png\" data-lbwps-width=\"750\" data-lbwps-height=\"574\" data-lbwps-srcsmall=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_2-300x230.png\"><img loading=\"lazy\" decoding=\"async\" width=\"750\" height=\"574\" src=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_2.png\" alt=\"Load or reload linetypes screenshot\" class=\"wp-image-16568\" srcset=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_2.png 750w, https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_2-300x230.png 300w\" sizes=\"auto, (max-width: 750px) 100vw, 750px\" \/><\/a><\/figure>\n\n\n\n<p>Notice the dialog wants you to select a file, and defaults to something called \u201cacad.lin\u201d. The acad.lin file is simply a text file containing all of the linetype definitions. Let\u2019s explore that file a little closer.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-acad-lin-file\">The ACAD.lin File<\/h2>\n\n\n\n<p>AutoCAD has two such files, the other being \u201cacadiso.lin\u201d for use in isometric drawings. They are stored in, and loaded from a folder in your user profile. More on that in a minute. Below is an image showing what it looks like. I\u2019ve scrolled down a bit, mostly to show some comments referencing Release 13 and 14, but also to show the more complex linetype definitions.<\/p>\n\n\n\n<p>Let\u2019s look at the definition for GAS_LINE, as we\u2019ll be using that an example for the tip part of this post. You have the name and description \u2013 including the graphic representation &#8211; followed on the next line by the rather cryptic definition of how the linetype is created. Trust me, you do not want to learn how to define these things. Check out the ACAD_ISO\u2026 definition at the top of the image. I\u2019m sure that the definition of \u201cA,12,-3,12,-3,0,-3,0,-3,0,-3\u201d makes total sense to you. Yeah, me too.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_3.png\" data-lbwps-width=\"931\" data-lbwps-height=\"899\" data-lbwps-srcsmall=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_3-300x290.png\"><img loading=\"lazy\" decoding=\"async\" width=\"931\" height=\"899\" src=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_3.png\" alt=\"ACAD.lin file screenshot\" class=\"wp-image-16574\" style=\"object-fit:cover\" srcset=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_3.png 931w, https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_3-300x290.png 300w, https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_3-768x742.png 768w\" sizes=\"auto, (max-width: 931px) 100vw, 931px\" \/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-actual-tip-creating-your-own-linetypes\">The Actual Tip: Creating Your Own Linetypes<\/h2>\n\n\n\n<p>By my count, there are 45 linetypes defined in the acad.lin file. Surely that\u2019s enough to cover every situation ever imaginable, right? Of course not. But having just filled you in on how they\u2019re defined, where would you even start if you had to create a custom linetype?<\/p>\n\n\n\n<p>That\u2019s where AutoCAD\u2019s Express Tools saves the day. Tucked safely away in the Additional Commands menu of the ET Tools panel, you\u2019ll find Make Linetype.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_4.png\" data-lbwps-width=\"950\" data-lbwps-height=\"336\" data-lbwps-srcsmall=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_4-300x106.png\"><img loading=\"lazy\" decoding=\"async\" width=\"950\" height=\"336\" src=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_4.png\" alt=\"Make linetype in AutoCAD screenshot\" class=\"wp-image-16571\" srcset=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_4.png 950w, https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_4-300x106.png 300w, https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_4-768x272.png 768w\" sizes=\"auto, (max-width: 950px) 100vw, 950px\" \/><\/a><\/figure>\n\n\n\n<p>Let\u2019s say we need to make the following (beautiful) linetype.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_5.png\" data-lbwps-width=\"315\" data-lbwps-height=\"150\" data-lbwps-srcsmall=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_5-300x143.png\"><img loading=\"lazy\" decoding=\"async\" width=\"315\" height=\"150\" src=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_5.png\" alt=\"\" class=\"wp-image-16577\" srcset=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_5.png 315w, https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_5-300x143.png 300w\" sizes=\"auto, (max-width: 315px) 100vw, 315px\" \/><\/a><\/figure>\n\n\n\n<p>The first step is pretty easy. Draw what you want it to look like. The second step is to launch the Express Tool, and follow its prompts. The next thing is tell it where to put the new definition. This location has changed often over the years, and now it defaults to your My Documents folder, using the format of &lt;drawingName.lin&gt;. Use that if you like.<\/p>\n\n\n\n<p>Or, you can go find the acad.lin file and your new linetype will be appended to the last section of the file. You can find it in the following location:<\/p>\n\n\n\n<p>C:\\Users\\&lt;yourUserName&gt;\\AppData\\Roaming\\Autodesk\\AutoCAD 202x\\R2x.0\\enu<\/p>\n\n\n\n<p>If you don\u2019t feel comfortable about editing this file, just use the default, and then you can cut and paste later.<\/p>\n\n\n\n<p>The next step is to select the start point and end point of your sample linetype. Don\u2019t forget to have an Endpoint Osnap turned on.<\/p>\n\n\n\n<p>Then, you\u2019re asked to \u201cSelect Objects\u201d. Select each element from left to right. Press Enter. Your custom linetype will be added to the .lin file, and will be loaded for the current drawing. It\u2019s literally as easy as that. Now, I can draw whatever I want, using my \u201cbest ever\u201d new custom linetype.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_6.png\" data-lbwps-width=\"439\" data-lbwps-height=\"247\" data-lbwps-srcsmall=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_6-300x169.png\"><img loading=\"lazy\" decoding=\"async\" width=\"439\" height=\"247\" src=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_6.png\" alt=\"\" class=\"wp-image-16580\" srcset=\"https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_6.png 439w, https:\/\/www.autodesk.com/blogs\/autocad\/wp-content\/uploads\/sites\/35\/2026\/09\/19\/Linetypes_6-300x169.png 300w\" sizes=\"auto, (max-width: 439px) 100vw, 439px\" \/><\/a><\/figure>\n\n\n\n<p>While you can write your own .lin file as I described, I suggest moving your new style into the Acad.lin file, just to make things easier going forward.
