Conversion from Topsolid to Onshape is not supported yet :(

TopSolid is a completely integrated CAD/CAM software which was created by the French company Missler Software. It is based on the geometric kernel ParaSolid. As it is fully integrated, it allows users to design and manufacture parts using the same software. There is a wide range of Topsolid industry solutions: from the more general, mechanically oriented (TopSolid’Design) to specific solutions.

Actually, there is a whole line of CAM products: mechanical machining (TopSolid’Cam), sheet metal (TopSolid’Sheetmetal), wood (TopSolid’WoodCam), wire electroerosion (TopSolid’Wire). TopSolid also incorporates additional modules: a 2D draft module (TopSolid’Draft) and a structural computation one (TopSolid’Fea).

TopSolid'Cam, one of the main products of Topsolid, manages multi axis machining such as 5 axis machining, mill turn operations, twin Spindle and twin turret technology.

TopSolid 7 is claimed to simplify the design and modification of large assemblies in an organized and structured environment.

Onshape is a CAD software system, delivered via internet. It is focused on mechanical CAD and is used for product and machinery design in many industries, such as electronics, machinery, medical devices, 3D printing, machine parts and industrial equipment.

It makes use of cloud computing, with computer-intensive processing and rendering performed on Internet-based servers. Users are able to interact with the system via a web browser or the iOS and Android apps.
