Week 1 The concept of design idea, basic technique of extrusion

1、 问题:The profile in the sketch must be exactly the same as the shape of the feature of extrusion.
选项：
A:正确
B:错误
答案: 【错误】

2、 问题:The color of fully constrained sketch is dark blue.
选项：
A:正确
B:错误
答案: 【正确】

3、 问题:The size of the feature can be different with the dimension of the views as if the size of the model is the same.
选项：
A:正确
B:错误
答案: 【错误】
分析：【The dimension reflects the size definition of the part. Only the same size of the model is not enough.】

4、 问题:The construction line is part of the sketch but not part of the prufile, it can be not fully constrained.
选项：
A:正确
B:错误
答案: 【正确】

5、 问题:If original plane or surfaces of existing feature do not meet the requirment of a sketch making  on it,  we have to create a work plane.
选项：
A:正确
B:错误
答案: 【正确】

6、 问题:For symmetrical extrusion, the input distance of the extrusion is the half of the feature size.
选项：
A:正确
B:错误
答案: 【错误】

7、 问题:In the feature of extrusion, we should make as more profile in a sketch as possible for higher modeling efficiency.
选项：
A:正确
B:错误
答案: 【错误】

8、 问题:In the modeling, we do not need to repeat identical feature, because we can duplicate it either in the sketch or in the feature level.
选项：
A:正确
B:错误
答案: 【正确】

9、 问题:In the command of symmetry in sketch, if there’s no symmetrical line, we need to make a construction symmetrical line first.
选项：
A:正确
B:错误
答案: 【正确】

10、 问题:The way of how to fulfill the command is depended on the known conditions.
选项：
A:正确
