1 - A “window" selection permits you to …

_ … choose the selection according to the chosen identity. … select more than one selection by using an elastic area made of various setting. … fix the maximum limits within which is possible to create geometric entities. … perform a dynamic zoom on a specific part of the graphic area. … capture entities which are linked one another.

2 - The coordinates system of a CAD/CAM system like Mastercam, is fixed and in any case can it be moved or fixed again.

_ True False

3 - Is it possible to create or edit some tests in order to obtain geometrical entities like lines and arches?

_ No CAD system can transform dimensions into geometric entities. A text is a raster picture which you can not vectorialize. Specific functions which permit you to transform notes into geometric entities. It is absolutely unuseful to create or transform textes into geometry.

4 - The Pan operation permits you to …

_ … edit the defined coordinates system. … change the point of view from which the drawing in the graphic area is visualized. … move the geometric entities to a hidden level. … move the geometric entities within the graphic area.

5 - Which is the goal of the CAD/CAM vision instruments ?

_ They permit you to exploit to the utmost the video performances of your PC. They permit you to personalize the system interface. They permit you to perform operations like zooming on the geometry. They permit you to create geometric entities within the graphic area.

6 - Which is the minimum number of point used to define a plane in space?

_ 4 3 6 1

7 - To open a drawing file coming from a CAD  system different from the original one you need to …

_ Make a copy and paste operation in the target system. Erase all the dimensions because they can create irreversible errors during a file conversion. Use the import operation of the target system. Erase all the color attributes linked with the geometric entities.

8 - Usually how is it possible to zoom in or out the real proportions of a drawing within a CAD system?

_ With the scale functions. With the zoom functions. With the edit of the building grid pitch. With the cut/extend functions.

9 - In a CAD/CAM system it is not possible to create geometric entities which lay on a plane different from the one defined by the X and Y axes.

_ True False

10 - The minimum number of point to define an arch is 2.

_ True False
