Sometimes, CAD can't select the target by trimming in three-dimensional conditions. The following tutorial perfectly solves this problem. The following is a CAD three-dimensional cutting course that I carefully arranged for you, hoping to help you.

Methods/steps

1 For example, draw a circle under the southeast isometric survey, draw a diameter in the middle, and click Trim.

After pruning to 2 o'clock, you need to press Enter once, and then select the target.

If we change the coordinate axis, as shown in the figure.

After pruning at 4: 00, the target cannot be selected, and the pruning cannot be completed.

5 Click Interrupt at this time.

6 Interrupt the selected target.

Click and drag with the left mouse button to achieve the goal.
