Additionally, I'd be thinking of outsourcing some simple drawing work (to someone interested and England-based), initially, to assist me with setting up a few standard templates, but also selecting fills, textures, and standards specific to materials, technology, and building regs in the UK (specifically, England).
Any feedback, or offers of assistance will be welcomed :-).
DM me if you prefer.
HighDesign is the closest CAD software to VW I have managed to find (although, still considerably more 'clunky' than VW, I think, but that may just be a lack of familiarity). As I really have no use for BIM in my line of work, it is a better/more affordable prospect (on the Mac) than anything else out there I have looked at.
Although I have used SketchUp since it's very early days, once I was forced to abandon VW, I also kept trying Layout - and, in turn, abandoning it as I find it particularly frustrating and unreliable: it's just a really badly written piece of software, missing many basic tools (such as a measure tool, and guides - all tools you would think they would carry across from SU!). It started out as an add-on, but now they (Trimble) are heavily pushing it as the production-tool solution. Additionally, not allowing users to create and share plugins has really hampered its development (the thing that really rocketed SU into the forefront of mass 3D design).
So, I find myself at a difficult juncture - stay with SU/LO, or continue with SU for design and modelling, and start from scratch with a new CAD package, such as HighDesign... it seems you are in the same space.
