Crankshaft's Sketchbook

Rough rendering of my engine room. My focus here was on getting the values right not so much the lighting.

This looks great!

How are you drawing this? Is it traditional and then scanned in? Or is it purely digital? Do you create perspective grids to help you, or do you just do it by eye?

Crank you amaze me with your drawings, so tech. I hope you keep doing well and I just wanted to say I enjoy watching these analytical sketches. I still stop from time to time whenever I can get the computer to peek on them

@Gus Thanks! I'm glad you like them! I thought most people would not have much interest in technical stuff.

@ Dom Early design sketches are done in pen and pencil which I haven't shown but will later. They're very messy. These final "place holders" are done in digital and yes I do use perspective grids but I now also have a solid understanding of perspective. I use the rough sketches as guides or blue prints that way the design goes thru little revision during the digital phase. Hope this helps.

Scaling in both one point and 2 point.



Scaling details in 1 point to either horizontal or vertical surfaces.



Some more anatomy study with horizon lines and perspective built in.

Elevated false horizon lines in 2 point and 3 point perspective.



Trying to cast shadows for triangular roofs.



Finally understood how to cast the shadow.

More studies. Complex shadows in local light. This one was really hard because it has a recessed triangular roof.



Making odd divisions on planes. This was something that I had to use for my engine room.

Studies for the next part of my engine room! These are a bit rough since I already knew what was going on in my head.

How to place slanted fins on a cylinder in perspective.



Same thing but with more accuracy.

Sneaky peek at my engine room! Hard core construction lines show how tedious and busy things can get! All those part designs will gradually be "installed" here .

Update on my engine room! This is the focal point, the electrical turbine. I wanted it to have a forward serrated thrust.



Evolution and references from work.



Putting it together.



Rough sketches of iterations.
