Your Prelim

You will be sitting a paper which is similar to the two past papers you took home over Christmas, therefore it is important that you look over these and practice any areas that you found difficult.  Try the drawings again for full marks, I have all the answers on tracing paper if you want to check your drawings.

Theory Topics:

• Colour theory - Primary, Secondary and Tertiary colours; harmony and contrast; moods and feelings colours give.
• CAD/DTP - All the GENERIC terms for different types of software, CAD commands and DTP features; different types of hardware: input and output devices; advantages and disadvantages (do not mention quicker unless stating quicker to produce multiple copies! And don't say cheaper.) Make sure that you answer the question asked i.e. advantages of computed modelling and advantages of using CAD to create architectural drawings are two different questions!
• British Standards - How to dimension: lengths, angles, radius, diameter; Line types: center, fold, outline, hidden detail, cutting plane; different drawings in a set for a new building: what you would see on each type of drawing and what scale would be appropriate.

 Drawing Topics:

For all drawing types: 

• Draw the crate first!  
• Keep construction light (and make sure you do it!) and keep your outlines darker but THIN so keep your pencils sharp.
• Remember that you have to be within a mm, so measure carefully.  You can also use your compass or bounce line to transfer sizes.
• Be aware of the time.  If you don't understand a drawing, leave it and come back to it after you have done the ones you definitely know how to do.

• Prisims/Cylinders - All shapes. Remember to number all the corners and use these to help you work out the drawing.  Use a bounce line to help transfer sizes because you can also follow the corner to the different view.  Remember your fold lines!
• Pyramids/Cones -  As above but remember that all your lines need to go towards the apex.  This means that the surface development will start as a circle. Every corner you draw on the bas line needs to go up to the apex.  Look at where the cut meets the corner and project this up to the plan and to the other elevation.  Always number your corners to make it easier to follow.
• Pictorials: Isometric, Planometric, Oblique - Take your time to ensure good measuring.  ALWAYS draw the crate first!  Then you have something to work inside and to measure from.  Remember that you will need a trammel and clockface construction for isometric circles.
• Assemblies/Sections - Take your time to ensure that you understand what the drawing is showing and how it pieces together. I would start with a complete view before trying to do the section view, or the view that requires using a compass to draw a circle.  Use a bounce line and LIGHT construction to plot out the section view before darkening in. Remember that hatching is only where you have cut through a material and not in the space and that this should be drawn at 45.

Dates for the diary

22/11/11 - CAD/DTP resit NAB - lunchtime

24/11/11 - Folio hand in

In order for me to write as detailed a report as possible on you, I require to look through both your Technical Graphics Folio (drawings) and the Presentation folio (DTP and marker rendering)  It is important that you use the time between now and then completing any unfinished drawings and making sure that I have the most up to date copy of your DTP.

Today's CAD/DTP Mini Test

Here are the questions and answers to today's mini test to use as revision for the CAD/DTP NAB on the 17/11/11 which is next time I see you.  As well as looking here I suggest that you look at the Can Do statements on the front cover of the CAD pack, use the homework sheets and the Leckie and Leckie book to make sure that you are comfortable with the answers for each.

a) The rectangle tool was used first of all to draw the body of the multimeter, and then another rectangle was used to draw the screen.
b) The chamfer tool was used to cut the bottom two corners off at an angle of 45.
c) The text tool was used to place the values on the screen.
d) The circle tool was used to draw the dial by drawing two concentric circles.  The circle tool was also used to draw the holes at the bottom of the multimeter.
e) The fillet tool was used to round the top two corners of the body of the multimeter.  A radius of 10mm was used.
d) A Linear Array was used to duplicate the same circle for the holes at the bottom of the multimeter, and space the 3 of them evenly in a line, equal distances apart.
e) The dimension tool was used to show the linear dimension of the overall height of the object and the radius of the curve of the fillet on the top right corner.

a) Facing Pages/Double Page Spread
b) Caption
c) Text Wrap
d) Bullet Point list
e) Drop Cap (when the first letter of a paragraph drops two or three lines)
f) Full Bleed (where an image "bleeds" off the page deliberately)
g) Margin
h) Footer or Folio

a) Flatbed Scanner, Digital Camera, Graphics Tablet, (maybe fax machine but that relies on the computer having fax software so this may not be accepted)
b) Laser Printer, Ink Jet Printer, Drum Plotter, Flatbed Plotter
c) Surface, wireframe, solid
d) Layering a drawing means that different details are drawn in different areas of a drawing which overlap like clear acetates.  This allows different elements to be switched on and off to help understand the drawing.  i.e. when drawing an orthographic drawing the outlines could be drawn in one layer, the dimensions in an other and centre lines in a third.  You could also show different levels of detail if required.

Today's CAD and DTP Mini Test

Homework set: Pyramid Extension sheet 2  for 21/11/11

Today we did the following questions to revise for the CAD/DTP NAB on the 17th of November.

a) The ring/Polar array was used to draw the circles indicating where the numbers would be on the clock.  First a circle was drawn and then a polar array drawn duplicating this first circle 11 times with a space of 30 degrees between each duplicate around  central point.

b) The pattern fill was used to draw the diagonal pattern on the duplicated circles.

c) The dimension tool was used to show the linear dimension of the overall width of the clock.

d) The mirror tool was used to copy the detail at the bottom and make it an exact mirror image of the original.

e) The line tool was used to draw two hands.

f) A linear array was used to draw the four buttons under the clock.  First one rectangle was drawn and then duplicated 3 times with uniform distance between each duplicate.

a) Heading
b) Subheading
c) Imported Graphic
d) Caption
e) Gutter
f) Boxed out Text
g) Text Wrap
h) Folio

a) Quick and easy to make copies, Quick to make alterations/correct mistakes, More accurate measurements, Can use a library for common parts, Can easily send copies to different locations, Can store drawings in different locations
b) + Can test out different textures + Can use it in simulation/animation to demonstrate features + Easier to store  - Can't physically touch it - Can't interact with the model
c) You can watch an animation i.e. create a video clip demonstrating how a folding chair can be folded and unfolded.  You can interact with a simulation and test out different situations i.e. Load the folding chair with different people and objects to see how it could withstand each.

Pyramid Revision

Hopefully this video will help you with your pyramid drawings.  This is pyramid 8 - the Octagonal pyramid.

Homework / NAB update

Today I gave back homework on CAD theory and pyramids.  This showed a need for further revision so watch this space!

Homework : CAD 4 due in on 15/11/11

                     Pyramid Resubmission (if required) on 15/11/11

NAB: Includes CAD and DTP terms on 17/11/11

You need to know generic CAD and DTP terms like those found in your homework sheets from both topics.  We will do some mini tests as revision in class.  You should revise by making yourself notes from the Leckie and Leckie book, and your DTP booklet.

CAD Revision

Here is a sheet to help you remember some of the CAD commands.

Remember that you need to know the GENERIC terms for the CAD commands because not everyone uses VectorWorks!  You can also use page 49 of the Leckie and Leckie Text book.
