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.
STP file contains 3D object project saved in STEP (Standard for the Exchange of Product Data) format. STP format is similar to less frequently used STEP format. STP is a ASCII text file that conforms to ISO 10303-11 standard specification, sometimes referred to as EXPRESS.
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 SKP file after converting to STP may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from SKP to STP 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 SKP to STP does not meet your expectations, you can simply try to find on the Internet a different version of your file in SKP format, properly converted to a STP file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file SKP the desired result was not achieved, you can try to change the format of SKP file to other than STP. 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 SKP file converted by someone else, and the attempt to convert it to STP 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 SKP file in its original format (without conversion to STP file). Such a solution will be difficult to implement, but it certainly will give the best result.
