I believe there is a real and valid need for a STEP and IGES translator for exporting of .pk2 and .bd2 format files in Modelling Express 4.0, without imposing on users to upgrade to the full version, as there are many users who have very low volume output of their CAD designs that do not allow them the justification to foot the hefty bill of incurring the installation cost of a full-fledged CAD programme. This is so that at least users of Modelling Express can communicate with users of other CAD programmes without hindering any work progress towards the aim of innovation.
