@dimitar and @ReD_CoDE apologies about the editing feature - I thought I had fixed it previously, this isn't the first time - but I just found out that the gamification feature (the ability to like posts and earn points) actually gives you ranks which affect your ability to edit posts. I've changed it to be 1 day editing as soon as you join. You should see a settings icon on the top right of your post if it is within 1 day.
I've also changed the editor to be a bit more obvious in how it works - the other one perhaps was trying to be too clever. This one is a bit simpler, and allows you to edit the quoted post. Hopefully it's better. If it isn't and people want the old one back I can change it back.
Now, to move back on-topic ... :)

We should note that there is a software space left open by proprietary software vendors: they are effectively required by various regulations to support IFC, but their business models dictate that they prefer proprietary data formats. So there is a real possibility that the best tools for working with IFC could be free software and that the big vendors won't care or won't be interested in doing anything about it.
I absolutely agree with this. I genuinely believe that the BlenderBIM Add-on is now the world's most advanced IFC authoring tool. The only competitor I think that comes close is SimpleBIM. No other IFC editor allows partial writing, geometric representation context control, distinguishes between the multiple colour assignment methods, lets you create your own property set template definitions, and now can store annotation too, among many more features. What's missing is people to test it out, teach it to others, and so on.
But it's more than just tools - it's about relationships, transparency, and a culture of wanting to do the right thing in the built environment.
