### An advantage of a wifeframe model compared to solid moned is that the

Wireframe model can be generated quickly, using little computing time

### You are using cad system to draw a polygon. After drawing a series of straight lines, you enter the letter C from the keyboard. You intend to:

Close the polygon.

### The term orthographic projection means to

throw forward the at right angles and draw

### What is incorrect about describing an object

The most desciptice view is typically the top view

### Orthographic projection is a system that allows you to make

two -dimensional drawings of a three dimensional object

### The precedence of lines tells us that if a visible line and a hidden line coincide (occupy the same position on the drawing) we should:

Draw only the visible line

### In most cases, you can completly describe the shape and size of an object by drawing

two or three views

### When making a multiview drawing of an object, you need to draw:

Only as many views needed to describe the shape

straight line projection

### When a curved surface is tangent to a place surface

No line should be shown where they join
