QueLab Drafting Class -- Online 2020

I am taking an online drafting class from QueLab, taught by Ethan Moses.



DAY ONE
August 5

First drawing
orthogonal and isometric


Second drawing
orthogonal and isometric

Homework Drawing
with missing forms


DAY TWO
August 6




Dotted lines
indicate hidden geometry


Making Ellispes
(without a compass)


Ellispe representing a circle
 in side isometric drawing


Hidden circle/ellipse


DAY THREE
August 7


Screen capture
of the project we were supposed to draw



Orthogonal drawings



Isometric drawing


Cross-section
isometric drawing


There are other 3D drawing approaches besides isometric, where all the angles are not 30 and 60 degrees -- axonometric drawing.





DAY FOUR
August 12

We used Onshape to create a simple cube object, with a few extrusions/intrusions.



A simple cube, 
with dimensions, an extrusion, and an extrusion
(plus a cylindrical plug in the center)



Using another sketch,
and the mirror and fillet functions,
to put dimples in the side



The object with dimples



My screen with the same
object as the instructor's screen above



I imported my object
and one of my drawings
into Blender


DAY FIVE
August 13


SECOND DEMO


After rotating a semi circle around an axis,
to make a sphere,
we rotated a circle to eat into the sphere
and make an apple core


We made a second cubic object,
and used it as a tool to subtract the middle of the sphere



We "mirrored" the apple-core sphere
in two directions



We used a plane to split the sphere



We rotated a split piece off 
the remainder of the sphere





We made a three side cube,
with interlocking teeth,
like one would make on a laser cutter



DAY SIX
August 14


We started with Margaret's project -- taken from an Instructable -- of creating a two piece wooden pyramid puzzle in Onshape.





We used the pentagon tool
to make a three sided object,
ie a triangle



We dimensioned 100 units
from the base to an apex of the triangle



Then we drew a triangle in an orthogonal plane,
giving the hypotenuse the same dimension of 100



Both the radius line and the hypotenuse line
had to "pierce" the exact midpoint
of the base triangle


Then we created planes
from all 3 sides of the base triangle,
at 60 degrees leaning in
to make a pyramid



Confusion


Then we extruded the base triangle
in the upward direction



We split the solid
with the 3 planes
to ultimately make a triangular pyramid






Then we split the pyramid
to create the two parts of the puzzle
(both with a square side
to fit together)




Front


Side


Orthographic






Ethan's quick way
by drawing one half
and mirroring it







So I had to export and animate:



I downloaded the 3D glasses 
from the Onshape public directory
