I am rather a noob with regards to Blender, but I have a solid background in 3D graphics and visualisation. I am stuck with a problem I have when I am trying to model a tile asset based on a cube with an additional extrusion. The problem I am facing is that my base cube has the dimensions 4m x 4m x 0.1m . Based on this I am doing a loop cut to seperate a part of the cube with a width of 0.5m. This part should then be extruded for a room height of 3m, so I am pressing “e” for extrude and enter “3” (for 3 meters) for the extrusion amount. The result can be seen in the attached screenshot, which shows me a horizontal edge length of 120m along the extruded edges. This also has effects on my later UV-unwrapping where the faces along the extrusion direction are strechted extremely compared to the other faces of my tile.
My question is: How can I correctly model the tile from my screenshot, so that I get correct metrical edge lengths afterwards?
Thanks in advance,
