【 Weak current College 】 CAD drawing principles--just for beginners

1 do figure steps: [a] setting maps (i.e., setting graphic limits); [B] set unit; [C] set layer; [D] to begin drawing.

2 always use the 1: 1 ratio in model space drawing, the drawing is finished in paper space (layout), Interior set printing percentage, plot.

3 is a different type of entity objects to a different layer color pen width.

4 mapping to the attention of the command line prompt, follow the prompts to decide what to do next, this can increase efficiency and reduce misoperation.

5 precise drawing, use the grid snap function, and set the grid snap value for appropriate spacing.

6 do not figure box and painted in a diagram, you can layout will figure box insert chunks (of course you have to make a figure box block), and then print out the map.

7 may be some common settings (such as: graphic boundaries, units, capture spacing, layers, callout styles, text styles, and other content) is set in a graphic template file, and then draw a new map, you can create a wizard, click the [model] to open it, and start drawing.
