Rhino is commercial as well as stand-alone 3-D modeling software. Commonly this software is used for making architectural designs, automotive designs, industrial designs, product or graphic designs as well as it has its applications in reverse engineering. It features a scripting language, based on Visual Basic and SDK that supports Rhino files to be directly read and writeable.
3DM is Rhino file format used for exchanging NURBS geometry. Its developers started NURBS for providing an effective tool to the graphic software developers for transforming 3-D images in applications. There are many image file and CAD formats that are natively supported by Rhino 3D model without external plugins such as: SAT, FBX, DWG, 3DS, BMP, TGA etc.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .3DM file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .3DM file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .3DM file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
