Here's my MUST requests:
1- import dwg or dxf or pdf into layout. Having to rastered your vectoriel or having to simply redraw it is REALLY not a cool thing.
2- Be able to choose a different folder for the autosave and the skb. That would fix a lot of sync problem with dropbox.
3- In layout, be able to have a "component" as well as groups. This is The most annoying missing feature in Layout. That cost me hours and hours of my time when using hundred of symbol for site plan.
4- In layout, be able to edit lines in group edit.Having to constantly ungroup and regroup could be a pain in a busy drawing.
5- In layout, Improve leader basepoint. When copy a group of details drawing with multiple leader, they not always fallow. Its very time consuming to reposition them everytime you move something.
6- In layout, create new layer when copy elements from different file. In LO2017, you need to manually create all the layer in the new drawing first! Annoying.
7- have a different extension for sketchup viewer so client CANNOT have edit your model and have access to your priceless library. This missing feature create serious political problem in companies.
8- Having a measurement tape in sketchup viewer. Basic simple essential tool!
