Crystal vs. Python vs. Site3D vs. Visual Basic Comparison Chart

Crystal’s syntax is heavily inspired by Ruby’s, so it feels natural to read and easy to write, and has the added benefit of a lower learning curve for experienced Ruby devs. Crystal is statically type-checked, so any type errors will be caught early by the compiler rather than fail on runtime. Moreover, and to keep the language clean, Crystal has built-in type inference, so most type annotations are unneeded. All types are non-nilable in Crystal, and available variables are represented as a union between the type and nil. As a consequence, the compiler will automatically check for null references in compile time. Crystal’s answer to metaprogramming is a powerful macro system, which ranges from basic templating and AST inspection to types inspection and running arbitrary external programs.

Comprehensive facilities include tools for road placement in horizontal and vertical, automated junctions and roundabouts, varying carriageway width, spiral curve transitions, super-elevation, interface grading, building pads, earthworks, ponds and drainage. Site3D works from the engineers' point of view. Having been developed within a civil engineering consultancy, the software works in the way that engineers think. The software is so intuitive that engineers often require no training in Site3D to deliver complex design schemes. The powerful interactive features in Site3D empower the engineer to deliver projects in a fraction of the time of traditional systems. Using Site3D allows engineers to get through more work and to produce more refined designs. Because Site3D makes it so quick and easy to modify any aspect of the design model, the engineer is able to try out many what if scenarios. This allows for a more honed and refined final design.
