Hello Iain,
iainc:
I am trying to import iges files into corel draw for use with a laser cutter. Do I need an external file converter to do this?
as mentioned by Paul, IGES is a specific 3D CAD file format and it is not supported by CorelDRAW. The good news is that Corel has just announced Corel DESIGNER Technical Suite X4 (think of it as CorelDRAW for technical graphics) and is offering an add-on for DESIGNER X4 that provides support for a long list of different CADCAM file formats, including IGES. Here is a link to the full list: http://www.corel.com/servlet/Satellite/us/en/Product/1213733084350#tabview=tab2
As a CorelDRAW Graphics Suite X3 or X4 customer, you are eligible to the upgrade price of DESIGNER X4, and you will need to add the Deep Exploration 5.5 CCE upgrade option to DESIGNER if you need access to IGES without having a licence os IGES on your system.
