Most of the people in the industry who consider Layout to be a toy have only used it for 30 minutes max, have tried to use it like ACAD or Revit/ArchiCAD, haven’t been able to get anything out of it and quit.
I know because this is how I and many of my friends approached layout. I bagged layout like all the others not knowing 10% of it.
Is it currently perfect? No. But it is quite capable ONCE you have your templates and workflow dialled in, and understand the various workflows that you need to use to get the required result.
This is no different to Revit which is quite frankly garbage out of the box but once you set it up right, is okay.
Most people always complain when approaching a new software, neglecting the 10, 15, 20 years of in-house development that went into making your preferred software tolerable. Spend the same development time in Layout and see what happens.
I suspect layout will receive some large updates in the coming years as Trimble re-aligns their product base more towards ACE. I can wait, hell I’ve been waiting 12 years for them to fix my favourite 1000 Revit bugs so whats the difference?
At the end of the day I need a software that I enjoy using, one that feels right and puts a smile on my face.
At this point I would still rather spend a week in sketchup and layout than a day in Revit, and I am a Revit master.
