Suppose I have a cube such as this:
This is a cube of 10x10x10 cm. I go into Edit Mode to extrude and then:
It says 1.27m but the cube isn't that high even after the extrude it wouldn't be this high. I guessed that maybe this is just 1.27 times the height of the cube but visually it doesn't look like it's 27% taller so I figured that's not the answer.
I thus have two/three questions.
What are these numbers? It obviously isn't the height of the original cube and it also obviously isn't the height the cube would have AFTER extrusion.
How do I extrude to a certain height/depth/width?. Say my cube is 10cm high, then I extrude this straight upwards to 15cm then rotate that top surface by a few degree and extrude at an angle and I want to extrude it to exactly 20cm height (such that the final structure is exactly 20cm tall).
How do I extrude to a certain amount in the direction of extrusion? Similar scenario but unlike extruding to exactly 20cm height I want to extrude 5cm into the extrusion direction (in which case the total height would be less than 20cm).
I also have a few side questions because I'm a beginner but that are unrelated to the problem I have but why does scale change with dimension? If the cube is 0.1m and the scale is 0.05 then it'd be 5e-3 and not 0.1m?
