Property used to determine the forces causing the motion of an object. YZ,XZ I am trying to subtract some 3D text from an object to make an indented text. with one "good" region (in Blue) and one "bad" region (in Red) ? Pasted as rich text. If you select multiple regions, only those that are coplanar with the first selected region are accepted. When you have completed this module, you will be able to: The mass properties of a solid object are its mass, centre of gravity, centroid, volume, moments of inertia, products of inertia and radii of gyration. I enter massprop. XY plane of the current UCS, the additional properties shown in the following table are displayed. Calculations that are derived from the products * dist Learn how BCcampus supports open education and how you can access Pressbooks. properties that MASSPROP displays depend on whether the selected objects (Figure Step 3). Even though these are extremely small values, to AutoCAD, these are 3 different planes. The one in the upper left is the one I have done already and worked, the rest I am having the described issue. At first i thought the ignored regions were the circles, but as i selected smaller groups of regions to try and zero down on those i believed to be the ignored regions while in the massprop command, i found that not all ignored regions are of a circular nature. If the object was a uniform solid, with no holes, the radii of gyration would be the radius the moments of inertia would use to perform its calculations around each axis. The moment of inertia is lowest through the second axis that is I'm Michael, new to this forum, and i stumbles upon a massprop command issue. selected 3D solids, surfaces, or 2D regions by subtraction. Ask the community or share your knowledge. The text is positioned mostly inside the object. Enter the MASSPROP command, as shown below, selecting the solid model on the left side. Create and Combine Areas (Regions) Create Revision Clouds.
(Figure Step 12), Locate the Top UCS at the end of the line (Figure Step 13), Using what you learned in Module 20, use the SECTION command, as shown below, to create a section at the location of the construction line you just drew. On layer: Construction, insert a point at the centroid of the model using the POINT command as shown below. Did you use the REVOLVE command or REVSURF?
