Hello,

Regarding dimensioning, in this final article we will study LEADER, TOLERANCE and CENTER MARK options by examples.

You can use LEADER DIMENSION to draw attention to locations where you want to show a definition or a property.

Command: _qleader

 

As shown in Fig.2, click on points 1, 2 and 3 respectively. Enter your text and text width. If you press ENTER once, cursor goes to the line below, if you press ENTER twice, you end the operation.

Fig. 2 Putting dead label.

You can either have the arrow to be shown as cross by turning Ortho off. By the time you don’t want to write text, you can double press ENTER after the second point and press ESC button.

By TOLERANCE dimensioning, you can give geometrical tolerances over the dimensions. When you press the command dialog box, which is seen below, opens up.

Command: _tolerance.

 

Fig.4 Tolerance dimensioning dialog box.

It enables you to express tolerances with certain symbols. When you click on the black box, you can see the symbols. You can also enter the tolerance you wish inside the white area.

With CENTER MARK command, you can mark centers of CIRCLE or ARC.

Command: _dimcenter

 

Select arc or circle: Click on arc or circle.

You can either put a marking at the center of the circle as seen in figure or by applying the settings explained by Orhan’s Dimension Style Settings 3: Dimension arrows and symbols article. You can place markings as seen below.

Fig. 7 Centermark may also be used as a set of axis.

Have a nice day.
