However, I would like to know how to trim off the top part with an extruded polyline surface. Thanks in advance. Go to Solution. Solved by omorah. Solved by j.
Your "Trim Surface Extrude. I can see only one extrudes surface the roof , the walls are missing. The file seem to have some issues.
I am attaching another CAD file. This current file is the base of my goal:. Each room has it's own interior perimeter wall line - for special electrical lighting calculation. Also, each room's perimeter walls should be joined as one unit - for volume calculation. Floor to under roof ceiling. The whole building also has it's own interior perimeter wall line - for volume calculation. All wall lines stops at under roof ceiling.
I hope I am not too explicit in my description in making my request more confusing. I am just trying to be as clear as I could be in my second language, English. The trim I did in the previous file went well, but, when I tried the same format in this file, I could not get it to work. Another way. Copy and paste where applicable. However, how about using a SURFACE, so, when it is shaded, one can see through to the floor and roof which Solids does not provide to have a hollow space?
Massprop you get only from solids or regions. Surfaces dont't let you calculate the massprops. If you need both solids and surfaces then I'd suggest, create both: - create the solids as shown above there are possible a lot of other workflows on a special layer or as many layers as you need for solids to get the mass informations.
Now you can "play" with the Layers. To get the massprops use the solids. If you want to see the surfaces turn OFF or freeze the layer s with the solids and turn ON the layer s where the surfaces reside. BTW: I did not yet understand why you need urgently surfaces? I'd do it as shown in the following screencast. If you need the volumina of the rooms, do not subtract the inner volumen, but: - copy the inner volumina once at the same place.

The curves must still have their construction history intact. Click the Cut button in the lower right corner of the window. Accesses operating system commands. Once you have your 3D object or even just a part of it, you can use the shell command to hollow it out with a pre-determined thickness.
Deletes selected objects. This option provides a convenient method to erase unneeded objects without leaving the TRIM command. It is used to remove extra lines or extra parts of an object. We can also perform trim using different selection methods. We are required to select the portion of the object to trim.
Extending operates the same way as trimming. You can extend objects so they end precisely at boundary edges defined by other objects. In this example, you extend the lines precisely to a circle, which is the boundary edge. Select cutting edges. Specifies one or more objects to be used as a boundary for the trim. A mesh model consists of vertices, edges, and faces that use polygonal representation, including triangles and quadrilaterals, to define a 3D shape.
Unlike solid models, mesh has no mass properties. You can drag mesh subobjects faces, edges, and vertices to shape the mesh object. An inside corner is called a fillet and an outside corner is called a round; you can create both using the FILLET command. Using grips to edit solids Grip-editing is one of the most direct ways to modify an object. To edit a 3D solid by using grips, select the 3D solid when no command is running, and then select the grip that you want to use to edit the solid.
The 3D solid or surface is formed within the space between various cross sections. The cross-sections determine the outer shape of the solid or surface.
