It enables the creation of 3D designs and 2D parametric drawing, the creation of technical drawings from designs, the addition of finishing touches, detailing, linking annotations with other data, workflows and process management. In this version PDF creation and integration are supported; PDFs can be used as underlays with snap-to features. There are new model documentation tools; users can generate drawings views for models created by AutoCAD and other modeling tools and the models can be updated to reflect engineering changes. The software can be bought boxed or downloaded in a very large file. You will need a device robust enough to run it; check out the system requirements before you download. The fully functioning version is available free of charge for 30 days; our view is that proficiency in its use may take longer to acquire and most users will need the training to do the product justice. Students can be licensed at a very low cost, otherwise the professional license is around £2,735 per seat.
