When you are in a command that asks you to select a point, Shift-right-click and select Geometric Center from the Osnap menu. You can also type Gcen↵. Place the cursor on the closed polyline or spline, and the Geometric Center osnap marker appears at its geometric center.
Where is the centroid of an object?
The point corresponding to the geometric center of an object is known as the centroid. Depending on the shape of the object, one, two, or three coordinates may be needed in order to define its exact position in space. If a shape possesses an axis of symmetry, then its centroid will always be located on that axis.
Where is 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.
Can AutoCAD find centroid?
How do you find the centroid of a shape in AutoCAD? 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.
What is meant by centroid?
centroid. / (ˈsɛntrɔɪd) / noun. the centre of mass of an object of uniform density, esp of a geometric figure. (of a finite set) the point whose coordinates are the mean values of the coordinates of the points of the set.
What is centroid in structure?
The centroid of a section is important in structural design and is like the centre of gravity of the shape. Most structural shapes have their centroid tabulated by the manufacturer. Many other simple shapes are symmetrical about the x-x and y-y axes and the centroid can easily be seen.
How is a centroid formed?
The centroid of a triangle is formed when three medians of a triangle intersect. It is one of the four points of concurrencies of a triangle. The medians of a triangle are constructed when the vertices of a triangle are joined with the midpoint of the opposite sides of the triangle.
What is the difference between center and centroid?
The center of gravity of any object is termed to the point where gravity acts on the body. Where on the other hand, the centroid is referred to as the geometrical center of a uniform density object.

How do you find the center of gravity?
The center of gravity of an object is calculated by taking the sum of its moments divided by the overall weight of the object. The moment is the product of the weight and its location as measured from a set point called the origin.
How do I use Massprop in AutoCAD?
MASSPROP Command
To use this command, type “MASSPROP” on the command line and press Enter. Then select the object from the drawing area and press Enter again. You will see that a list will pop up above the command line with all of the object’s properties, as shown in the image below.
