ENGR1304: Tolerances in CAD

Draw a rectangle (just for something to add labels to)

In Annotate, click on "Tolerance", or type TOLERANCE into command line.

To add a Datum label - just type "A" in Datum 1, hit "ok"

>Enter Tolerance Location > click where you want your label to go. You can move the box around later if you need to.

To automatically add a tolerance label with a leader line:
type QLEADER<settings>

Note: You might have to re-size your datum arrows and text - just right click on it, select properties, and change it.

Now let's add a geometric tolerance box, that shows one side should be perpendicular to A with a tolerance of .0004.

Type in "QLEADER", choose <settings>, tolerance, choose your arrow head, draw in your leader line,

Click on symbol, and choose what you want to do.
.

Table of symbols from your book:

Next, add your tolerance in, and Datum reference:

It will create a box with your tolerance symbol, values, datum points, and anything you filled out.

To add text notes:
Type in "LEADER"
Specify 1st point - click on a side of the rectangle (this is where the arrowhead will be)
next point - click outside of rectangle.
<Annotation> enter
Then type in your text.
If you hit enter without typing anything in, it will end the command.
Note: you can go back later, double click on your text, and edit it.

Note: go to help, type in:

"Text Symbols and Special Characters Reference"
Get the Unicode codes for different symbols.

%%o – Toggles overscoring on and off.
%%u – Toggles underscoring on and off.
%%d – Draws degrees symbol (°).
%%p – Draws plus/minus tolerance symbol (±).
%%c – Draws circle diameter dimensioning symbol .

%%% – Draws a single percent sign (%).

Text Editor>Symbol

Choose "Other" to get:

Create a dimension, Double click on it, and edit it.
You can add another line, of text, or you can double click, then right click, then select "symbol"

For this one, I just used 2 text boxes. You can add dimension lines, then explode it, and then re-size arrows / text etc. independently.

Assignment: Do pg 307 on CAD (or on Autodesk Inventor if you prefer):

Create the 3D object, then create the Base Views from model space in a layout, then add in all the tolerance boxes.
