3DM format is an 3D model format available as open standard used by Rhinoceros 3D software. 3DM file stores 3D model data, for example, information about surfaces, curves, and points. 3DM files can also store metadata and formatting attributes.
File with SKP extension contains 3D model or element of such model. This file format is native to SketchUP software tool. SKP is a proprietary binary format, and as such its documentation was never released to the public. However, SKP libraries are available to the public.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the 3DM file after converting to SKP may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from 3DM to SKP to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting 3DM to SKP does not meet your expectations, you can simply try to find on the Internet a different version of your file in 3DM format, properly converted to a SKP file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file 3DM the desired result was not achieved, you can try to change the format of 3DM file to other than SKP. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your 3DM file converted by someone else, and the attempt to convert it to SKP on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the 3DM file in its original format (without conversion to SKP file). Such a solution will be difficult to implement, but it certainly will give the best result.
