CHARACTER OF GEOMETRIC AND SYMBOLS By Dian Pramesti, S.Pd

  The table below presents the types of geometric character which can be controlled by the geometric tolerance symbols for use on drawings.

Geometric Tolerances Table image

In the geometric tolerance that show the diversity of shape, location, and position, often required other geometric elements in the same component as the basic element. Based on the basic elements of the relationship specified geometric tolerance, the tolerance of such a good, tolerance profile, orientation tolerance, where tolerance, and tolerance spinning.

WRITING TERMS OF TOLERANCE SYMBOLS ON IMAGES

To differentiate with other symbols, geometric tolerance symbols shown with the following conditions:

Working drawings hub , in Auto CAD drawings in attaching symbols and geometric tolerances

a. SQUARE GEOMETRIC TOLERANCE

Symbol of tolerance and requirements in writing at the geometric tolerance box is divided into two or more, the use of AUTO CAD program can help in making geometric tolerance box by way of:

1. Click on the tool bar Dimension AUTO CAD standards
2. Click on a sub section of Tolerance Dimension
3. In the Geometric Tolerance dialog box click on the symbol and its geometric tolerance of the desired geometric tolerances
4. Click OK and place the geometric tolerance symbol in AUTO CAD drawing work area

b. APPOINTMENT OF ELEMENTS THAT GIVE IN GEOMETRIC TOLERANCE

Geometric tolerance box is connected with a given tolerance of geometric elements with lines pointing the tip of the arrow must be attached. use of AUTO CAD program can assist in the appointment of elements given by the geometric tolerances:

1. Click on the tool bar Dimension AUTO CAD standards
2. Click on a sub section of the Leader Dimension
3. After that place the appointment of geometric tolerances given element by clicking on a given field of geometric tolerance point for the geometric tolerance towards the box
