Question:
Why are my guidelines so long? Can I possibly shorten them a bit?
Answer:
By default, the length of guidelines corresponds to the total length of the grid area displayed (see Image 01). However, you can simply adjust this length in the program using the "Work Plane and Grid/Snap" feature. Furthermore, it is also very convenient to adjust the grid automatically to the size of the model. The length of the guidelines is also changed accordingly (see Image 02).
