DIMENSIONING

>>>> LEARN THIS! <<<<

All Manufacturing and Fabrication industries depend on Drafting. Without Drafting, nothing can be manufactured.

The “drawings” that companies use to “Work” from are called “Working Drawings.” A Working Drawing must have enough information that someone could build the object as specified.

If you have taken Metalwork or Woodwork and you can actually build off a set plans, you have a HUGE advantage over the kids who have not.

AS A DESIGNER OR ENGINEER, YOU ARE THE ONE WHO MAKES DRAWINGS DETAILED ENOUGH TO BUILD FROM

A Working Drawing must include:

- All the necessary views to explain the shape
- All the dimensions and specifications needed to build the object to size, using the proper materials

ASK YOURSELF – “Can this object be built without further instructions?”

We need to talk DIMENSIONS

Dimensioning is one of the MOST IMPORTANT parts of Drafting

LEARN THIS!

- One view is dimensioned AS MUCH AS YOU CAN
- On one view has WHATEVER ELSE YOU NEED
- THE LAST VIEW IS NAKED

ONLY show the dimensions you NEED to show to BUILD the object – NOTHING MORE.

DO NOT DIMENSION EVERY SINGLE LINE THAT EXISTS!

NO REDUNDANT DIMENSIONS (never dimension the same thing twice!)

BE LAZY!
ONLY DIMENSION WHAT YOU HAVE TO!

DIMENSION LINES

Dimension lines have ARROWS pointing to EXTENSION LINES.

Extension Lines DO NOT touch the object.

Dimension lines start 10mm from the object and then 8mm apart from each other

Overall dimensions are OUTSIDE smaller dimensions and SHALL NOT CROSS

To prove that you are reading this, show this sentence to me for a bonus mark.

Do not duplicate dimensions

WHICH VIEWS??

Dimension on the CLEAREST VIEW, usually:

- First: on the front view
- Secondly: on view that shows the detail the best
- Lastly: only if needed, on the remaining view

Dimensions go BETWEEN THE VIEWS

Dimensioning to CORNERS is better than LINES

DO NOT Dimension to hidden lines

(if you dimension to hidden lines, I’m going to punch you in the hidden line)

(Show me this sentence for a free “don’t punch me in the hidden line” card)

CIRCLES, HOLES, & ARCS

ARCS are dimensioned by RADIUS (you use a compass to draw them)

HOLES are dimensioned by DIAMETER (you use a drill to cut them)

YOU MUST DIMENSION HOLE CENTERS!!! (Where is the hole located??)

ALL IN ONE EXAMPLE:

This has everything

ASSIGNMENT

ENGINEERING DRAWINGS (“Working Drawings”)

Tutorial 8 DO NOT CONTINUE WITHOUT BEING CHECKED!

Problem 8 – Create Engineering Drawings for Problem 1

BONUS (especially if you WANT to be an Engineer):

Problem 8b – Create Engineering Drawings for Tutorial 4

- - - Dimension the location of the hole?
    - Dimension the size of the hole?
    - Dimension the center of the Radius?
    - Dimension the size of the radius?
    - Dimension the radius on the edges?
    - Dimension the overall height?
    - Dimension the overall width?
    - Go back and read the rules of dimensioning

Problem 8c – Create Engineering Drawings for Tutorial 5

- - - Dimension the shape of the revolve?
    - Dimension the sizes of the holes?
    - Dimension the distance of holes from center?
    - “Leader” to say “C-BORE” and counterbore size?
    - Go back and read the rules of dimensioning

Problem 8d – Create Engineering Drawings for Tutorial 6A (Hair pin)

- - - Dimension the path?
    - Dimension the profile?
    - Convince me that you’ve learned this

SHOW your instructor the Problems on screen (I want to KNOW that you got this), then send the PDFs to the handin folder.

GET CREATIVE!

FUSION 3-PART CHALLENGE!

The parts shall count THREE, no more, no less. THREE shall be the number thou shalt count, and the number of the counting shall be THREE. Four shalt thou not count, neither count thou two, excepting that thou then proceedeth to THREE. Five is right out.

This Project must be completed THIS TERM;
Don’t waste your time

Don’t waste OTHER PEOPLE’S time;
THEY NEED TO COMPLETE THEIR PROJECT TOO

>>> NO WEAPONS <<<

No derivatives of weapons, no miniaturized weapons, no functional or non-functional weapons, no insinuated weapons, no historical weapons, no futuristic weapons, no theoretical weapons, no philosophical weapons, no psychological weapons, no cleverly disguised weapons, no weapon components that could later be assembled into weapons, anything that looks anything like anything that could have anything to do with any kind of weapon is forbidden. Get over it.

THE PROJECT MUST BE 4 THINGS:

If you can read, now is a good time to do so:

1. Be a GADGET, TOOL, or CONTAINER
  - (check out the MARKS SHEET – the HOOP you must jump)
    - A: Each shape has extra techniques, TWO parts move as a SIMPLE MACHINE, and, when 3D Printed and assembled, does not come apart.
    - B: Each shape as extra techniques, TWO parts move, when 3D Printed and assembled does not come apart
    - C+: Each shape has extra technique, something moves, when 3D Printed and assembled does not come apart
    - C: Basic geomteric shapes, something moves, when 3D Printed and assembled does not come apart
    - !!MOVING PARTS MUST HAVE ABOUT 1.5mm CLEARANCE!!
      .
2. Be ASSEMBLED from ONLY THREE DISTINCT PRINTABLE ASSEMBLEABLE parts
  - A Single Part can have more than one technique applied
  - “Single Part” example: A bicycle wheel (though it is made of many pieces, it is considered ONE part):
    - Rim (revolve)
    - Hub (revolve, hole, pattern)
    - Spokes (sweep, thread, solid)
    - Tire (revolve, solid, pattern)
    - Valve stem (revolve, thread)
  - You have permission to use “real” screws, springs, metal pins, and the like, as fasteners if need be
    .
3. Something MUST MOVE yet remain ATTACHED When 3D printed and assembled
  .
4. Use at least THREE DIFFERENT TECHNIQUES:
  - Solid modeled parts
  - Holes
  - Shells
  - Ribs
  - Revolved parts
  - Patterns
  - Lofted parts
  - Swept parts
  - Sheet Metal

HAND IN 5 THINGS:

If you can read, now is a good time to do so:

1. PRINTED 3D – Project (Click HOW TO 3D PRINT)
  .
2. PRINTED Engineering Drawings Booklet (PDF) (IE: Tutorial 8?)
  - Page 1: TITLE PAGE with RENDERED VIEW (RENDERED!!!)
  - Page 2: ASSEMBLY (no dimensions) (Use the “+” to add pages)
  - Pages 3, 4, 5, etc…: PARTS – one page for EACH individual part (with dimensions)
  - PRINT THE MARKS SHEET for marking
  - BOOKLET (not project!) EXAMPLES
    - These are how I want your booklets to look:
3. EXPLODED ANIMATION (IE: Tutorial 9?)
  - EXPORT All *.avi files
    .
4. DIGITAL – ALL Project Files
  - EXPORT All *.f3d *.jpg *.doc & etc. files
  - CREATE A FOLDER labelled lastname_projectname, and COPY ALL your files into it.
    - example: wellwood_sheet-metal-brake
  - DRAG AND DROP the folder to “i:\1. Handin\!Wellwood”
    .
5. PRINTED MARK SHEET (below)
  - PRINT for marking
  - YOU mark yourself FIRST
