every time I extrude and scale with it it comes off at an angle, is there any way to fix this?

For some reason when I extrude the pentagon, it also extrudes on the Z axis and not just on the X and Y axis.  Can't figure out what I'm doing that's different from the video.  Doing E +S and dragging and it's just changing Z height on it's own.

at 6:26 i can't make the 45 angle to move the loop downward ...and even if i do the g+z key it goes 1 side only.. .Please let me know how to do it.

whenever I tried scaling and extruding to make the launch pad, it keeps pushing my vertices downward and creates faces

Found a useful alternative to select multiple faces like a loop cut under Select/Select Similar/Perimeter

Under View menu found the hotkeys for Frame Selected Numpad . & Frame All Home key are really useful in speeding up my workflow.

When you're using the three button mouse emulator, you can loop select by double clicking instead of using alt+left click. :)

So excited that I know something!! hehe

I followed the video and have assigned materials but when I go to material preview mode everything is white.  I have found how to set a colour in the solid display mode but still nothing but white in materials preview.

i am on an old iMac running 10.11.6 but these old macs won’t update any later system.

Any ideas?

I'm not sure what I did, but panning and rotating in the world view (moving around) is now INCREDIBLY slow. 

Use to I could fly around easily panning, spinning the viewport. But I must have fat fingered something because now it's incredibly fine grained. Any idea what I might have done?

At 7:00, you said to extrude along the z-axis by using "e+gz", extrude, grab, and lock to the z-axis; was this meant to be "e+z" as in extrude and lock to the z-axis? What is  the difference?
