As a new ROBLOX developer, it is currently hard to measure the distances between objects if, for say, you want to align another object between them.
If this issue were addressed by the addition of a new “Ruler” tool, it would be a lot easier to measure the distance between 2 surfaces without needing to spawn a part in and use the properties tool.
This tool would be another button where the Select, Move, Scale, Rotate, and Transform buttons are, with a tape measure icon.
When currently in use, you would be able to click on a surface, and then click on another one, wherein a line would be drawn between the 2 surfaces with a number on top (e.g. 201.75 studs). To prevent errors by selecting 2 parallel surfaces in different locations, the measurement is based on axis, not the length of the line.
Other popular 3D modeling software already have this tool, like Google’s Sketchup.
