1 - What is a "draft"?

_ It’s the group of joints and bevels pu on th external edges of the tridimensional model. It’s the angle where the spacial model lays regarding the referring system. It’s the scale factor which permits to calculate the retiring of pressing materials. It’s the inclimation imposed to the die walls in order to make the oucome of the finished piece easier.

2 - A revolution surface is obtained by …

_ … with the rotation of a generating curve round a defined point. … with the translation of a transversal curve round a longitudinal. … with the rotation of a generating curve round a rotation axis. … with the rotation of a closed profile round a point.

3 - Thanks to the analysis functions it is possible to evaluate the volume of surfaces and solids model.

_ True False

4 - Is it possible to import a surfaces model create with a CAD system different from the original one?

_ No, the importation and exportation of CAD files is possible only with bidimensional entities. Yes, thanks to both proprietary and independent exchanging formats. Yes, but the exportation of a 3D surfaces model leads to the creation of a solid model. Yes, but the exportation of a 3D surfaces model leads to the loss of building profiles.

5 - What is the construction plane?

_ It’s the orientation with which the piece is visualized in the graphic area of a CAD system. It’s the level where all the dimensions and the building profiles of 3D models are put. It’s the organization of the working cycle you need to create a tridimensional model. It’s the plane where geometric entities are created and positioned.

6 - Can specific modelling functions change a solid model into surfaces.

_ True False

7 -During the modelling phase is it possible to make a cut one surface?

_ No, the surface must be definetely created in origin. Yes, but the cut can be made only with a straight line. Yes, both with profiles and other surfaces. Yes, it is possible to perform a cut only with a closed profile.

8 - What is an extrusion in a solid modelling?

_ A function that permits you to extrude a solid model from a surface one previously created. An operation that permits you to create only holes on an existing solid model. An operation described by the positions taken from a section running on a straight line. An operation described by the positions taken from a section running on a curve.

9 - Is it possible to insert quotations on a solid model?

_ No, the dimensions are a prerogative of bidimensional tables. Yes, a solid model can be dimensioned. Yes, but you need to create the bidimensional tables of the model first. Yes, it’s possible to insert the dimensions but not the notes.

10 -During a solid modelling it's not possible to make a cut on a solid object with a surface.

_ True False
