Press enter twice to accept the values and exit the command. Select ltScale from command line again and change its value to 1.5, this will increase the linetype spacing to 1.5 times of the initial value. Select Lweight from the command line and type 1 and press enter. You will see that the command line now shows lots of options related to the center line. Type CHPROP on the command line and press enter, then select the center line and press enter again. Alternatively, you can also use CHPROP command.Īs an example, I will change the linetype scale and linewidth for the current center line. The properties of these center lines and center mark such as linetype, linetype scale and linewidth can be changed using system variables as mentioned on this Autodesk knowledge network page. In this case, also the center line will remain attached to their lines and changing the position or orientation of lines will change the center lines as well. If the lines are intersecting then the center line will pass through the angle bisector of the lines as shown in the image below. The center line will be automatically added in between the selected lines. To add a center line select the Centerline tool from Centerlines panel of Annotate tab and click on the two lines. Centerline:Īs the name suggests this tool will add a center line in between two parallel or non-parallel lines. You can change the size of this extended length from the quick properties palette or manually using grips of center mark. The default centerline extends beyond the circle circumference. Select No from the show extension option to hide the extension line from center mark. Double click on the center mark to bring the quick properties palette, in the bottom of quick properties palette you will find an option for hiding the extension line. You can modify the properties of this center mark using properties palette. When the radius of this circle is changed using grips or using properties palette the center mark will adjust its size to the new dimensions of the circle. You will notice that a default center mark will be added as shown in the image below.īy default, the center mark will span the complete diameter of the circle and it will remain so even when you change the radius of the circle. The cursor will change into a Pickbox, click on the circle or arc and press enter to exit the command.
To add a center mark to a circle or arc select this tool from Centerlines panel of Annotate tab. In this article, I will explain how you can leverage the benefits of these AutoCAD tools to the best possible extent, let’s start with Center Mark tool.
With the help of these tools, it’s now fairly easy to add a center mark to an arc or a circle, you can also add a center line with ease using the center line tool. Among one of the many new features of AutoCAD 2017 was the introduction of Center Mark and Centerline tools.
