Convert the area into a region. Set the UCS at the lower left corner point of the object. Find the Centroid (CG) through the ‘Massprop’ command (i.e. 17.4, 17.0 or 15.8, 13.1 ) which gives the dimensions of the CG from the lower left corner of the object.
How do I get CG in AutoCAD?
To find the center of gravity, you need to first convert the mass element to a 3D solid, and then use the MASSPROP command.
- Select the 3D Solid object.
- Right-click. Click Convert to > Mass Element.
- Enter Yes on the command line to erase the selected object.
- Press ENTER, or enter N to name the mass element.
How do you find the centroid of a shape?
To calculate the centroid of a combined shape, sum the individual centroids times the individual areas and divide that by the sum of the individual areas as shown on the applet. If the shapes overlap, the triangle is subtracted from the rectangle to make a new shape.
How do I calculate area in AutoCAD?
Note: The results are shown in the command window. Press F2 to open the command window if the results aren’t visible.
To Calculate the Area of a Selected Object

What is geometric center in AutoCAD?
Geometric Center is an Object Snap option that was added to AutoCAD 2016. … This works like the center Object Snap option you select this option and move the mouse to the Edge or close to the Centroid of the Object in question. When the Icon appears select and the Centroid is selected.
What is an AutoCAD region?
Regions are 2D areas that you create from closed planar loops of objects. Valid objects include polylines, lines, circular arcs, circles, elliptical arcs, ellipses, and splines. Each closed loop is converted into a separate region. All crossing intersections and self-intersecting curves are rejected.
How do you find the center of gravity of an irregular shape?
Taking the sum of the average value of the weight/volume times the distance times the volume segment divided by the weight will produce the center of gravity.
What is the center of gravity?
centre of gravity, in physics, an imaginary point in a body of matter where, for convenience in certain calculations, the total weight of the body may be thought to be concentrated.
What is a mass element in AutoCAD?
Mass elements are primitive parametric objects that have specific shapes, such as arch, box, cylinder, and gable. They function as the building blocks of conceptual design (also schematic design) in AutoCAD Architecture 2021 toolset.
How do you find the center of area?
How to calculate the centroid of an area
- Separate the total area into smaller rectangular areas Ai, where i = 0 … k. …
- Calculate the coordinates (xm, ym) for the Centroid of each area Ai, for each i > 0.
- Calculate the overall Centroid x,y-coordinates as the average of all xm and ym coordinates.
How do you find the centroid of an arbitrary area?
Steps to find the centroid of composite areas

- Decompose the total area to a number of simpler subareas.
- Find the centroid of each subarea in the x,y coordinate system.
- Find the surface area and the static moment of each subarea.
