After working on some designs with the new block shapes, some additional gaps have come up. I'd like to see the following: Double Beam: two beams spaced apart, such that they can go on the end of "Wall Double". Or another way to look at it, take "Wall Sloped C Double Low" and turn them into square beams. Centered half-wall: Take "Wall Low" and move it up so it is centered. The main use for this is to use it rotated like this: In this way it can be used as a mounting point for a light or grow light without needing to put a whole wall. Duct blocks: I'd like to see Cylinder L, and all the Cylinder Thin variants and connectors, also have square versions (which are basically a cube quarter except centered). The purpose of this is to make square-looking pipes, which are common for air ducts. You can do this with Cube Quarter and Cube Eighth to an extent, but not all connection variants exist, and furthermore they are not centered so you can't do something like stick a Grow Light on the end of it. I really want a mount for a grow light that I can hang from the ceiling in a large warehouse, the Cylinder L used to work for this but no longer does since the Grow Light art was changed. Ventilator blocks: Would be nice to have a ventilator on the slope side of Ramp C. It would also be cool to have a Cylinder with a vent on the end of it (but not the sides), so you can make a vent that looks like it is hanging from a ceiling pipe. This also suggests it would be nice to be able to texture any faces which do not have the ventilator on it. Heavy Windows: There is a 45 degree heavy window with a frame on the top and bottom (Window G) however since the overhaul of heavy window shapes, there are not enough blocks to go with it. There should be a 45 degree window with no frame, and a 45 degree window with a frame on only the bottom (top if rotated). Those would also require corresponding variants of Window H. Container Extension Blocks: Ramp A Double, Corner Double A1 would be nice.
