AutoCAD is a powerful software used by professionals in the field of architecture, engineering, and design. It offers a wide range of tools and features to create accurate and detailed drawings.
One commonly used feature is the ability to show dashed lines in AutoCAD layouts. Dashed lines are useful for representing hidden or non-visible elements in a drawing, such as construction lines or dimensions that are not part of the final design.
Step 1: Creating a Dashed Linetype
To show dashed lines in AutoCAD layout, you first need to create a dashed linetype. Follow these steps to create a custom linetype:
Open the Linetype Manager:
In AutoCAD, type ‘LT’ in the command line or click on the ‘Linetype Manager’ button located on the ‘Home’ tab of the ribbon.
Create a New Linetype:
In the Linetype Manager dialog box, click on the ‘Create’ button. This will open the Create or Append Linetype File dialog box.
Name Your Linetype:
Enter a name for your linetype in the ‘Name’ field. Make sure it’s descriptive and easy to remember.
Select Pattern Length Units:
Choose whether you want your linetype pattern length to be defined in inches or millimeters from the ‘Pattern Length Units’ drop-down menu.
Create Your Pattern:
Now it’s time to define your dashed line pattern using text characters and spaces. Each character represents either a visible segment or an empty space.
For example, if you want a simple dashed line with dashes being three times longer than spaces, you can use ‘- – – – – -‘. To create more complex patterns, you can use different characters like ‘*’, ‘. ‘, or ‘_’.
Save Your Linetype:
Once you’re satisfied with your linetype pattern, click on the ‘Save & Close’ button to save your linetype.
Step 2: Applying the Dashed Linetype in Layout
Now that you have created a custom dashed linetype, you can apply it to the desired objects in your AutoCAD layout. Follow these steps to apply the linetype:
Select Objects:
Use any object selection method (e.g., click and drag, window selection, or individual selection) to select the objects you want to apply the dashed linetype to.
Open the Properties Palette:
In AutoCAD, type ‘PROP’ in the command line or click on the ‘Properties’ button located on the ‘Home’ tab of the ribbon.
Change Linetype Property:
In the Properties palette, locate the ‘Linetype’ property and click on its current value. This will open a drop-down menu showing all available linetypes.
Select Your Custom Linetype:
From the drop-down menu, scroll down and find your custom dashed linetype that you created earlier. Click on it to apply it to the selected objects.
Step 3: Controlling Linetype Scale
Once you have applied the dashed linetype to your objects, you may notice that it appears too dense or too sparse depending on your drawing scale. AutoCAD allows you to control the scale of your linetypes for better visualization. Follow these steps to adjust linetype scale:
Open the Linetype Scale Manager:
In AutoCAD, type ‘LTS’ in the command line or click on the ‘Linetype Scale’ button located on the ‘Home’ tab of the ribbon.
Set Linetype Scale:
In the Linetype Scale Manager dialog box, adjust the scale factor using either a numerical value or by selecting from a list of predefined scales. Experiment with different values until you achieve an appropriate appearance for your dashed lines.
Apply Linetype Scale:
Once you’re satisfied with the linetype scale, click on the ‘OK’ button to apply the changes.
Conclusion
Showing dashed lines in AutoCAD layout can enhance the clarity and readability of your drawings. By creating custom linetypes and applying them to your objects, you can effectively represent hidden or non-visible elements.
Remember to adjust the linetype scale as needed to ensure optimal visualization. With these simple steps, you can easily incorporate dashed lines into your AutoCAD layouts and create professional-looking drawings.
