Topsolid online Help Index
In most new releases of TopSolid, new objects, interfaces and methods or properties are made available.
The version number in which the object/ interface/method/property has been created is given at the top of its description page, like this:
Created: v<version>
Where <version> is the number of the version in which it has appeared for the first time.
When running your program on an older version of TopSolid, it is your responsibility to ensure that you are not going to access a resource that is not available on that release.
To do so, the simplest way is to check for the version number of TopSolid at the beginning of your program (ex: Checking for version).
Your program will not run correctly (i.e. crash at some point) on any TopSolid which version number is lower than the highest creation deletion version number of the resources you need to access.
