I think it’s perfectly reasonable to expect app functionality on the level of Inventables Easel or Silhouette Studio, for example. I’m comfortable using Fusion 360 and 90% of the time I would probably prefer it, but there are those times you just want to draw a circle around something.
I of course have no knowledge of what Glowforge’s plans are, but to me it is strange that many forum regulars seem to have the attitude that everything is pretty much done and we should be making our peace with the limited functionality available. The glimpse we saw of the iPhone app coming soon should be a reminder that a company like Glowforge probably has plans stretching for years into the future, multiple versions out. One thing that’s fairly obvious about the architecture of this machine is that it’s designed with latent capabilities that will be unlocked through software updates. And somewhere, down in a product backlog, there is a full suite of drawing tools. That doesn’t mean it will make it high enough in the priority list to get done soon, but I would be astounded if they haven’t thought about it at all.
