Lesson4

Lesson (Week) #6,

EGR-110-40, Burgener, Monday October 2nd, 2000

Administrative notes and announcements:

Oh, to avoid currupting your drawings, please close your drawing BEFORE pulling your floppy out. If your drawing remains on the screen, there exists a slight "capillary" link between the screen and your floppy. Breaking this link causes SOME files to get currupted.

Collected: Page 26 orthographic "complete the views" puzzles. A few people got near perfect papers earlier on Page 27, and don't need to turn in Page 26. I'll repeat their percentages again on Page 26.

Returned: Plots of the Page 158/221 CAD problems. Most people got perfect scores (I graded them in a good mood and in a rush). A few still need help with LTSCALE, and Linetypes. I'll review these concepts at the start of class tonight.

Quiz review: Questions?

Quiz: Time limit?


New AutoCAD Solid commands:
EXTRUDE(on Solids Toolbar, AND on Solids Editing Toolbar)
Review: PEDIT, LIST
UNION (on Solid Editing Toolbar)

FILLET for solids (Same old FILLET you already know)
At this point, you SHOULD be able to complete the Page 248, FIG. 8-1-B assignment (see last week's webpage for sample)

If time permits, we'll continue solids modeling and editing with:
BOX (on Solids Toolbar)

WEDGE (on Solids Toolbar)
SLICE (on Solids Toolbar)

UCS control: 3-Point p637, X, Y, Z rotation p636 and View (On UCS Toolbar, or type-in "UCS")
UCSICON Origin (Menu View>Display>UCS Icon)



Due next week: AutoCAD 2D and 3D Solid, Page 248, FIG. 8-1-B, Shaft Base, including full-section, and solid model, as shown below. Use 1/16 for spotfaces. Egnore surface finishes. See sample below.
