Pro/E comprehensive skills tutorial: dimensioning skills (Figure)

After the section is completed, start to set the dimension parameters of each geometry. First, select the unit to be set with the left button, and then use the middle button to calibrate the position of the dimension parameter. The following describes the calibration methods for various types of parameters.
Length of the line segment: Select the line segment with the left button, and then use the middle button to calibrate the position where the size parameter is to be placed.
Horizontal or vertical distance between two points: Select two points and then specify the appropriate position with the middle key to generate horizontal or vertical parameters.
Radius of a circle or arc: Select a circle or arc and specify the appropriate position.
The diameter of the circle:
Circle on the plane: Select the circle with the left button twice and then position the position with the middle button
Vertical cylinder: first select the circumference, then select the center line and then select the circumference, and finally specify the position.

Figure 2.1: Standard method for vertical cylinder dimensions
The angle of the arc: first select the end points of the arc, then select any point in the arc, then specify the position.

Figure 2.2: The method of arc angle
Distance between two parallel lines: Select two parallel lines and then calibrate the position where the size parameters are to be placed.
The angle between two non-parallel lines: Select two non-parallel lines and then specify the appropriate position.
The distance between a graphic unit and the centerline: Select the unit and centerline, and then specify the appropriate location.
The parameters of the irregular curve are specified:
Select the two ends of the curve and mark the horizontal or vertical distance between the two ends.
First generate a reference coordinate ç³¸, then mark the horizontal and vertical distance of the two ends of the curve, and indicate the relative position of the coordinate ç³¸ and any end point. Next, select the curve and coordinate ç³¸, then press the middle key, then All points in the curve are related to the coordinate point, and each point can be defined by the coordinate value.
Steps to read the punctuation file and create an irregular curve:
First make the irregular curve reference a certain area coordinate, select " Dimension ", use the left button to select the irregular curve twice, then the irregular curve turns red.
Then use the left button to select the coordinate to be referenced, and then press the middle button to complete the establishment of the reference relationship.
Mark the position of the first and last points of the irregular curve and the reference coordinate ç³¸.
Select " Modify " and select the irregular curve.
Select " Read Pnts ", enter the file name, and read in the coordinate point.
Select " Regenerate " to complete the reading of the coordinate points.
The user can also use the " Save Pnts " command to archive the data points of the irregular curve. The data format is as follows:
Coordinates of spline points:(they may be edited using available editor; changes in X and Y coordinates of the first and the last points will be ignored)CARTESIAN COORDINATES: XYZ 1 1 0 5.332236 3.37746 0 6.280372 9.575447 0 8.054441 11.43259 0 10 5 0
Angle of the end point of the irregular curve: first select the end point of the irregular curve, then select the reference geometry of the angle to be marked, then select the curve body, and finally specify the angular position.
