Correct Answer
A. Use Union to join them
Explanation
To create one solid model from two or more separate solid shapes, the drafter needs to position them correctly and then use the Union command to join them. This command combines the shapes together, removing any overlapping or intersecting portions and creating a single, cohesive solid model. The Join command is not the appropriate tool for this task as it is used to connect separate lines or arcs. Similarly, the Add Parts tool is not relevant as it is used to add additional components to an existing solid model.
20.
CAD programs which incorporate parametric modeling utilize a system in which the dimensions control the ________.
Correct Answer
A. Size and shape of the model features
Explanation
CAD programs that incorporate parametric modeling use dimensions to control the size and shape of the model features. This means that the dimensions inputted by the user directly affect the geometry of the model, allowing for easy modification and adjustment. The perspective of the model and the shading used to render it are not controlled by the dimensions, but rather by other settings and parameters within the CAD program. Therefore, the correct answer is that the dimensions control the size and shape of the model features.
