NaroCAD 1.4.5 is released. It builds on top of 1.4.4 release and adds improvements on how you work building your shapes and many small changes are in place to make you feel more like at home. If earlier you may miss a property or two in the property grid by either is a bug or a missing, right now all are there. You also have the poly-line tool that is made from multiple lines. A locking point to point constraint is also handy. Another area that got an overhaul is the capability that command line can be used in more contexts, meaning that some constraints that previously were not possible to edit excluding just from property grid, they are right now there. Also a great overhaul is on solver. Creating extrudes with same height are not an issue right now, but this is not the only change, you will likely remark that a lot of the magic points really appear where you expect them.
Those are only the user seen released. The code did get cleanup, so if you just want to see a clean C#/.NET codebase, is a good place to start, is working better with transformations, and not only.
