Assembly Pattern Data

Define the pattern data in the dialog box. The content of the dialog box and the features used vary depending on the pattern types.

Dialog Box Options

Linear
Defines the pattern as linear. You can define a linear pattern in an assembly in one direction or in the length and width directions.
Polar
Defines the pattern as polar. For a polar pattern, the number of components, angle or angle spacing is specified.
Polar with pitch
Defines polar pattern with pitch.
As an example, stairs.

With guide curves
Create a part pattern along a line or tangential line chain. Select the desired lines to the Guide curves list.
Example: Strand

Number
Enter the number of parts to be added in the pattern.
  • For a linear pattern, separately to length and width directions.
  • For a polar pattern, the number of parts on one circle.
  • The total number of parts to be set on the guide curve and the polar pattern with pitch.
Number: In the length direction of a polar pattern
Enter the number of overlapping polar patterns.
As an example, on the left the length=3 and on the right the length=2

Formula
Enter a variable for the pattern property (for example Number, Length, Width), which can be used when the assembly is varied using the dimension table. variable.

Length: For a linear pattern
Enter a value for the total length of the pattern, on which the components are placed at equal intervals. The direction of the positive X axis determines the longitudinal direction in the assembly (default). To check the directions of the axes, press the K button to change the cursor into a coordinate axis cursor. If necessary, rotate the pattern using auxiliary functions.

Example: A linear pattern in the length direction only: Number of components 5, length L = 120.
  • You can enter either Length or Delta, one excludes the other.
  • If you enter the length, the delta is calculated.

Length: For a polar pattern
Enter the total height of the overlapping patterns.
  • You can enter the Length (L) in Length-direction or the Delta. One excludes the other.
Delta: For a linear pattern
Enter the distance between the parts in the the length or width direction.
Also defines the vertical spacing of the parts for the pattern Polar With Pitch.
  • You can enter either Delta or Length, one excludes the other.
  • If you enter the delta, the length is calculated.

Example: A linear pattern to both directions: number of components 2, delta D = 50.

Delta: On the circle of a polar pattern
Enter the angle between two pattern members.
  • You can enter either the angle or the delta (D). One excludes the other.

Delta: In the length direction of a polar pattern
Enter the spacing between two overlapping polar patterns.
  • You can enter the Delta (D) in Length-direction or the Length. One excludes the other.

Delta: For the polar pattern with pitch
Enter the "vertical" spacing between two parts.
  • You can enter the Delta (D) in pitch direction or the total pitch. One excludes the other.
Width
Enter a value for the total width of the pattern, on which the components are placed at equal intervals. The direction of the positive Y axis determines the latitudinal direction in the assembly (default).
Example: A linear pattern in the width direction only: Number of parts 3, width W= 50.
Example: A linear pattern in both the length and width directions (angle = 90 degrees).

Radius
The radius defines the value of the radius in the geometry, type of guide curve, PATTERNPOLAR.
  • Note that the radius value will not affect the radius of a polar pattern.
The actual radius of the pattern is determined by the mutual position of the origin of the selected part and the guide curve PATTERNPOLAR.

Angle: For a linear pattern
Defines the angle of a linear pattern.
  • The angle of a symmetrical pattern is 90 degrees

Angle: For a polar part pattern
Defines the angle at which the components will be set at equal distances.
  • You can enter either the angle (A) or the delta. One excludes the other.

Pitch
Defines the value of the total pitch
  • Only available for types: Polar With Pitch.
  • You can enter the total pitch (H) or the delta in the pitch direction. One excludes the other.

No rotation
An asymmetric component rotates in a pattern by default. You can prevent rotation of the component by selecting the No rotation check box.
  • Only available for types: Polar and Polar With Pitch.
  • The feature is rarely used.
Example: On the left, the rotation is enabled and on the right, not.

Locating point
Define a point from the part or assembly that is projected to the line. The default point is the part's or assembly’s origin or handle.
For best results, select a part’s or assembly’s point that is also on the curve.

Distance: With guide curves
If you entered a Delta value, you can choose whether the distance is calculated Along Curves or Straight.

Deleted
Defines which components are deleted from the pattern. The position of the component is given as XY coordinates inside parentheses. A period (.) is used to separate the X and Y coordinates. In the Deleted field, you can enter several components to be deleted one after another, for example (1.1)(1.3). The parent component is (1.1). You can define components to be deleted when creating or editing the pattern.
You can delete individual components from the pattern by entering one of the following in the Deleted field.
  • (n.1) - Delete the last component on the first row.
  • (n.n) - Delete the last component on the last row.
  • (n.*) - Delete the last component on every row.
  • (*.n) - Delete all components on the last row.
If you have deleted components by using the Delete function, the coordinates of the deleted components will be displayed in the Deleted field when you select the pattern for editing. You can edit the data by adding or deleting coordinates.
Edit a pattern by deleting the following components: (1.2)(2.1)(2.3)(3.2)(4.1)(4.3)(5.2).
In a polar pattern, the parent feature will have the coordinates (1.1). The numbering continues clockwise: (2.1)(3.1), etc.
Delete a Component from a Pattern

Edited
When a feature pattern has been created of a local part, and a part other than the first one in the pattern has been edited, its coordinates are displayed in the Edited field just like the coordinates of a deleted component.
If there are asterisks inside parentheses in the beginning of the field (*.*), all parts of the pattern are separate instances. You can then edit each part of the pattern separately, including the first part of the pattern. If you clear the Edited field, all edited parts will be replaced with the original part.

Pattern Location
Defines how the pattern is positioned in the assembly. Select one of the following options:
