How do I search for an object in AutoCAD?
Hi, You can use SELECTSIMILAR command. Draw something in layer you need to explore, call SELECTSIMILAR command, then enter Settings option and uncheck everything except “Layer”, then pick object you just created and AutoCAD will select all objects in that layer.2 mai 2013
How is moment of inertia calculated?
Moments of inertia can be found by summing or integrating over every ‘piece of mass’ that makes up an object, multiplied by the square of the distance of each ‘piece of mass’ to the axis. In integral form the moment of inertia is I=∫r2dm I = ∫ r 2 d m .
How do you find the centroid in AutoCAD?
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.

How do I find Section properties?
The elastic section modulus is defined as S = I / y, where I is the second moment of area (or moment of inertia) and y is the distance from the neutral axis to any given fiber. It is often reported using y = c, where c is the distance from the neutral axis to the most extreme fiber , as seen in the table below.
