GD&T offers more control for complex shapes, such as position tolerances and flatness symbols. Though it can be confusing at first, it improves manufacturing accuracy and efficiency. Understanding GD&T can reduce errors and enhance drawing precision. If you are new to GD&T, I recommend starting with some online courses that explain the fundamentals. Engineering Toolbox or certain CAD YouTube channels will be incredibly helpful. Also, the ASME Y14.5 standard is extremely important in learning the application of GD&T. After learning the basics, you can practice using a CAD program to see how these symbols apply to a part and affect its manufacturing.

Hi! I am creating a 2D drawing for the bracket of an electric motor, which requires precise specifications regarding the placement of holes and the flatness of surfaces. This drawing is for production purposes, so it must be accurate enough to satisfy the described criteria. However, I need assistance regarding the proper means of illustrating the details. Which approach is more suitable: using linear dimensions or GD&T (Geometric Dimensioning and Tolerancing)? What are the benefits of using GD&T over conventional methods, and what issues does it present, if any?

When incorporating GD&T symbols into a workpiece, a CAD program like SolidWorks offers numerous features that make adding these tags to a model easier. Further effective use of these tools is covered in most tutorials, so you don’t need to worry about the learning process.
