We all know about Layout’s shortcomings when it comes to speed. Hopefully, that will be addressed in due course. In the meanwhile, here are some more minor improvements that I for one would find useful.
The default setting is Raster because it is fastest. We are advised to do all preliminary work using raster viewports and leave changing them to Vector or Hybrid until the end. It’s good advice but also a bit of a pain. It means you have to go through every page and every viewport changing them. What about a single button that would change the render settings for all SU viewports in one hit? It would have to be an option as you don’t necessarily want them all changed to a single setting. But it would save a lot of hassle.
When you choose a Text Box, you can pre-select a size for the text to fit into. Most of my text is Label Text for which that option is not available. It would be very handy if it was. Maybe when you pull a label from en entity, you would get a default box. If you ignore it, it would work as it does now. But you would have the opportunity before typing of pulling it to a size of choice.
When you create a box, you generally know how wide you want it to be but not how high. Often you end up altering it after the event or have to choose Size to Fit. I cannot think of any occasion on which you would want the box to be too small (though you might want it to be overlarge). So what about having the height be automatically determined by the text it has to contain but still allow it to be altered afterwards as you can now?
I find I often need to add text to explain a dimension. You can replace the dimension with text and include the dimension with it but that’s a dangerous thing to do. You might alter things that alters the dimension but the dimension text would stay the same. So the ideal would be to have the ability to add free text as an adjunct to the dimension, leaving the dimension dynamic. This is a commonly available feature in other CAD software.
