3D drawings are always flat.
2D drawings are used for 3D printing.
None of the above.
Which of the following is a benefit of 3D modelling?
It helps visualize complex structures before construction.

To color objects
To adjust lighting
None of the above.
Which problem occurs when a model is not properly attached to the base of the workplane?
The model will be too large
The model may detach during printing
The model will have too many details
The model will not be colorful
None of the above.
In which of these situations is the Ruler tool NOT helpful?
Finding the distance between two objects
Finding the angle between two objects

Make it invisible
Reduce the size to the minimum
None of the above.
What happens if tiny details are too small in a 3D model?
They will not be printed properly
The print will be faster
The model will be stronger
