![]() Notes from Cadalyst Tip Reviewer Brian Benton: This tip actually has five tips inside it: The first is that there is usually more than one way to do something in AutoCAD. AutoCAD will list the x and y coordinates of the centroid of the triangle in the AutoCAD Text Window." Next use the MassProp command and select the newly created region. It will then ask you to select objects: pick the three sides of the triangle, if the triangle was made using lines, or the whole triangle if it is a pline, then use the Enter key to finish the command. Start by entering Region at the Command line, followed by the Enter key. "The second method to find the center of a triangle is to turn the triangle into a region. It will place a point at the center or centroid of the triangle. Although it may not appear to be picking anything, rest assured it is picking the intersections, provided your aim is good and they do indeed intersect. ![]() Your mouse pointer will be replaced with a pick box carefully select the three intersections of the triangle. Next, AutoCAD will ask you for the > expression: Type in the expression (INT+INT+INT)/3 followed by the Enter key. Type in ‘CAL followed by the Enter key, which will activate AutoCAD's internal calculator (the apostrophe before the command allows it to be operated transparently while you are in another command). Start by entering Point at the Command line, followed by the Enter key. Set the PDMode to the desired configuration (I prefer the setting of 3 that way, X marks the spot). I like to place a point there so I have something I can reference later if I need to dimension to it. "First, I will use AutoCAD's internal calculator to place a point at the center of the triangle. For example, I occasionally need to find the center or centroid of a triangle, and I've found two different ways to do so. "I have found that there is usually more than one way to accomplish a task in AutoCAD. Projecting 3D Objects to Section and Profile Viewsĭean Culver explains two methods for finding the center of a triangle in AutoCAD.
