1 - In a CAD system as in general geometry, what is a spline?

_ A straight line parallel to an axis. A circle quadrant. A polynomial curve defined by knots. A generic angular dimension. A joint tangent to two different arches.

2 - Is it possible to export a drawing file on a CAD system different from the original one?

_ No, every CAD system creates only proprietary files. Yes, every CAD can create all the extensions for different systems. Yes, thanks to both proprietary and independent exchanging formats. No, because the format export generates problems in the geometric tollerance.

3 -Mastercam can create quotations and notes on a given drawing.

_ True False

4 - The Mirroring operation permits you to …

_ … create symmetrical entities to a defined axis. … rotate by 180° round a point the selected geometry. … create a tridimensional effect on the shown geometry. … proportionally edit the drawing dimensions.

5 - What is the main reason why a CAD system uses levelled distribution of geometric entities?

_ To reduce the created file dimensions. To have a better organization of the shown geometry. The quicken the system performances. To delete the building entities that are not necessary for the representation.

6 - A concatenation selection permits you to  …

_ … create defined groups only by linking points, lines or arches. … find entities with a coincidence between the ending point and the starting point of the following entity. … create entities within the geometric tollerance of a drawing. … give a parametral bond between two different enities.

7 - Usually which is the scale factor that permits you to zoom an object by 20%?

_ 1/10 0.80 1.2 +80%

8 - A modern CAD system can define only 2D geometry, while a CAM can create even 3D models.

_ True False

9 - Can the functions of each CAD system define the graphic characteristics of all the entities?

_ Yes, you can define the colors, kind of lines and thickness that are shown only during the printing phase. You can define all the attributes but not the colors. The attributes are automatically defined according to specific common standards. You can set and edit all the geometric entities specific attributes.

10 - In a CAD system, analize a geometric entity is like insert a quotation.

_ True False
