Function
- Point Grid
Assign the spacings and display area of point grids.
Point grids are displayed according to the initial preferences setting in Environment View of Tools > Preference. Use the function to change the preferences temporarily.
Point grids are displayed in the UCS x-y plane. Use View > Grids to display or not to display the point grids. Use the function in conjunction with Point Grid Snap for convenience.
- Line Grid
Assign the spacings of line grids to display on the screen.
Point grids are evenly spaced in each direction whereas line grids may be spaced unevenly.
Line grids are displayed in the UCS x-y plane. Use View > Grids to display or not to display the line grids. It is more convenient of Line Grid is linked to Snap.
Line grids may be assigned with names and as such, they can be accessed as necessary.
Call
From the Main Menu select [View] tab > [Grids/Snap] group > [Grids] > [Point Grid]
From the Main Menu select [View] tab > [Grids/Snap] group > [Grids] > [Line Grid]
Input
Point Grid tab
Grid Spaces
dx, dy
Point grid spacings in the UCS x, y-directions
Enter only dx if dx and dy are equal.
Model Boundary
Enter the grid boundary if the point grids are to be displayed only in a particular range. Check Apply To Grid Boundary.
Enter Xmin, Ymin, Xmax and Ymax consecutively.
Observe the following examples :
Enter only '20'
Xmin = 0, Ymin = 0, Xmax =20, Ymax =20
Enter '20, 30'
Xmin = 0, Ymin = 0, Xmax = 20, Ymax = 30
Enter '10, 15, 20, 30'
Xmin = 10, Ymin = 15, Xmax = 20, Ymax = 30
Line Grid tab
When defining or adding a new Line Grid
Click thd Add button to enter the following items :
Grid Name
Name of the Line Grid
X - Grid Lines
Click the Add button to enter Line Grids in the UCS x-direction
Absolute : Enter the line grid positions by absolute coordinates
Relative : Enter the line grid positions by relative coordinates (ie, spacings)
Line grids are generated relative to the UCS origin point.
Enter negative numbers if line grids are to be generated in the negative (-) range. Repeated equal spacings may be represented by 'Number of Repetitions@Spacing'.
Y - Grid Lines
Line grids in the UCS y-direction are identically generated following the procedure used to enter X-Grid Lines
To modify the position of an existing Line Grid
Assign the relevant grid in the line grid list and click the Modify button.
To remove an existing Line Grid
Assign the relevant grid in the line grid list and click the Delete button.
