CAD at a remarkable price

(continued...) The zoom level and layer visibility can be set for each view frame to achieve comprehensive sheet layouts including detail views.

Although this method is fine for 2D only projects, laying out multiple projected views from a 3D model is cumbersome compared to best of breed modellers that offer automated drawing layout facilities.

3D performance is said to have been increased substantially including support for 3D specific hardware.

Although there is little doubt that complex models can be created, geometry access for subsequent editing is limited compared to features and history based parametric modellers.

An entity history tree is available from the help menu but this does not allow selection or editing of the entities.

Parts can be edited by stretching, Boolean operations or added features, but simple edits like changing the radius of a fillet are far from easy.

Functional limits are also apparent in the ability to only apply fillets to straight edges or to round a corner.

The range of Boolean operations is very good however with variants such as Exclusive Or subtracting the common volume and Segregate that creates a solid of the common volume.

Solids can be created from a range of primitives, or by extruding, revolving, sweeping or lofting sections.

Surface patches can also be created and be converted into solids using the Solid Define command.
