Detail cube glass

With the current setup its impossible to make it so that any window size or shape that a player might want is available without overfilling the block menu to an absurd degree. But the 25cm grid system offers a solution that lets things be a little bit more dynamic.

The idea is that there are 25cm glass detail cubes with all of the cube shapes. When you have a mass of glass cubes that are all adjacent to each other and are painted the same colour then they have the process used to define the borders of identical coloured armor used in them except instead of just drawing weld lines in between the different planes it actually uses that to determine where to borders of each pane of glass is. Glass blocks that share a pane have a shared hitpoint pool so that if you shoot at the glass then it will all break at once and you can use the fancy glass destruction tool, but for any size and shape of pane. If there are deeper glass blocks then they add to mass but don't add to hit points, meaning a double-layered glass pane is the most protection you can get since two windows will need to be broken for the 2 visible panes (the outside pane and the inside pane) but having 3 or more layers won't add any more protection, with the glass blocks that aren't part of a pane just disappearing when their adjacent glass blocks break (creating a chain reaction to clear out any extra glass).

As an alternative for places where you want windows but want it to be extra protected you could do heavy-duty windows which use 50cm blocks instead of 25cm ones, but otherwise work the same.

Having the windows get broken up if they're different colours is great because it means players can divide the window frames up however they desire.

For this to not be incredibly tedious to make any windows that aren't made of cubes and aligned with the grid, such as corner windows or sloped windows then you would need to use something like this (https://support.keenswh.com/spaceengineers2/pc/topic/46102-better-plane-building-with-ctrlshift) to make building planes that aren't straight on easier. But it would also solve the corner glass windows problem perfectly. (https://support.keenswh.com/spaceengineers2/pc/topic/45800-glass-windows-do-not-fit)
