Drawing on a sketch plane has become a problem for me. No red flags in history and it is a problem that re-appears. It can take 20 seconds and seems in my opinion as a long-term user to have to do with history which in my opinion is a disaster itself year near 2026. It seems to be a job of ours to develop your software through sending you our files and on that I disagree strongly.  
After years of subscription I ask you kindly to start looking at competition if you intend to continue with updates.

I have as I started suspecting seen that it has to do with lofting, my problem. I would like to ask you to work on these features a bit more in-depth. As some of the surfaces seemed to occasionally disappear I started to think it might be the problem. I had to “re-fire” these “solids” in history to get them “whole” again and as I simplified my approach in a new project it showed most likely to be the problem.  
Lofting/sweep/fillet as well as blend is of course not the easiest to use/understand but is often very important and I’d like to see your way of improving and implementing.  
Please look at improving the Items window with a better “tree” and the history is in some ways “freaky” to me.
