Polyboard and StairDesigner
For both Polyboard and StairDesigner, the free/demo version has the same functionality as the full version except for manufacturing output.
You can design and optimise your projects, control feasibility and show off your projects in 3D but you cannot print or export cutting lists, plans and manufacturing files.
You can buy the software which comes with this functionality integrated, but you don’t have to.
See the article How do I get manufacturing documents from Polyboard and StairDesigner? for your options.
OptiCut and OptiNest
You can download the demo versions of OptiCut, OptiNest and CalepiLight to test out all the functionality. They will output optimized files but these will not include all the information required for manufacturing. Please request a sample cutting list or nesting output to test in your workshop.
