Replicate selected parts, faces, or features and arrange them in a row or grid pattern. Create new parts or modify existing parts by adding or removing material, or intersecting parts in its path. For information on creating circular patterns, see Circular Pattern. Linear pattern may also be used during an active sheet metal operation.

The Linear pattern feature replicates parts, features, or faces in a Part Studio along a linear path. This video shows how to pattern the tabs, slot, and Fillet features to create additional instances. Select the Linear pattern feature from the feature toolbar. Next, choose Feature pattern as the pattern type.

Select "reapply features" to regenerate the feature for each instance, instead of simply recreating the initial pattern instance. Select the feature to pattern from the Features list or from the graphics area. In this case, select multiple features to pattern the tabs, slots, and fillets. Next, select the Direction field and specify the Direction to pattern. Select a face or plane to pattern in the normal direction of the selected reference, or select an edge or linear sketch element to pattern along its direction. Adjust the distance between instances, and set the Instance count to 2. The Instance count includes the original seed feature. Reverse the pattern direction with the opposite direction arrow. Click the checkmark button to accept the linear pattern feature.

Add more cuts to the spindle. The first cut is centered, and more instances are required on either side. Select the Linear pattern feature and select Face pattern as the pattern type. Select all 3 faces of the cut to pattern. Next, select the right face of the sliding jaw to pattern normal to that face, and adjust the distance between instances. Adjust the Instance count as well. Check Centered to add an equal amount of instances to the left and right of the original faces. Add more instances by setting the Instance count to 18.

A red appearance is applied to the extra tooling body part near the jaw plate. Use this tooling body to remove geometry from the jaw plate and create a grip pattern. Select the Linear pattern feature utilizing the Part pattern option. Remove material by selecting the Remove option. Select the tooling body part as the Entity to pattern, select an edge for the Direction, change the Distance, and adjust the Instance count.

Check Skip instances to skip specific pattern instances. This can be helpful when encountering conflicting geometry or when specific instances should be excluded from the pattern. Onshape displays a selection point outlined in gray for each instance. You can skip an instance by selecting its respective selection point or using a box selection to select multiple instances to skip. The selection points of skipped instances are displayed with a red outline. Finally, specify the Merge scope of the pattern, or the part from which material is removed. In this case, specify the jaw plate.

A hole has been created to attach the jaw plate to the sliding jaw. To create more instances of the hole, select the Linear pattern feature and choose the Feature pattern type. Start by creating a pattern across the plate from left to right. Choose the hole to pattern, and select a linear edge in that direction. Set the Distance, Instance count, and reverse the direction using the opposite direction arrow. Check reapply features and skip the middle instance of the hole.

Another row of holes is required. Check Second direction, choose an edge from top to bottom, and input the Distance and Instance count. Use the Linear pattern feature to create several instances of features, faces, or parts parallel to a linear edge or normal to a planar face.

  1. Click Linear pattern feature icon.

  2. Select a Result operation type:
    • New - Create new material that results in a new part.
    • Add - Create new material and add to the existing material.
    • Remove - Take material away from existing material.
    • Intersect - Leave material only where geometry overlaps.
  3. Select the pattern type:
    • Part - To pattern an individual part
    • Feature - To pattern a specific feature (or features) listed in the Feature list (an extrude, fillet, sweep, sketch, etc).
    • Face - To pattern a specific face on a specific part
  4. With focus on the Entities to pattern field, select entities to replicate into a pattern.

    When selecting Faces to pattern, the Create SelectionCreate Selection arrow icon can be useful to select related faces.

  5. Set focus in the Direction field, and then select an edge or face of the part or a Mate connector (implicit or explicit) along which to place the replicated pattern entities.
  6. Enter the distance between each pattern entity, and then the number of repetitions, or Instance count (the minimum number of instances you are able to use is 1). Select a direction for the pattern in the workspace (shown below as the highlighted edge).
  7. Use Centered to make the seed instance/face/feature as the center of the pattern.

    In this case, the instance count is N instances from the seed (inclusive of the seed) in one direction and N instances from the seed (inclusive of the seed) in the other direction. With N being the number you enter in the Instance count field in the dialog:

    Example using Linear Pattern tool

  8. Select second direction to extend the pattern in a second direction; select the second direction.
  9. Check the Skip instances option to specify instances of the pattern to skip:
    • Click the instance's selection handle to add it to the list of instances to skip. The Skip instances list displays two numbers to indicate the instance: the first is the position from 0 in the first direction, and the second value is the position from 0 in the second direction.

    • Click the X next to the instance in the list to add it back to the Part Studio.
    • Click CLEAR to remove all instances from the Instances to skip list.
  10. (Feature pattern type only) Select Reapply features to regenerate the feature for each instance (specified in Instance count), in lieu of simply recreating the initial pattern instance.
  11. Click Accept checkmark icon.

Pattern an individual part:

Pattern a sheet metal part; in this case the blue outer wall was selected:

Example of a Linear pattern on a sheet metal part

Pattern a specific feature (or features) listed in the Feature list (an extrude, fillet, sweep, sketch, etc) without Reapply features selected (a faster, more lightweight feature pattern). This is not available for sheet metal.

In the following example, the initial extrude was Up to next (bringing the extrude up to the face of the surface). Without Reapply features selected, the features patterned (extrude and fillet) are patterned from the initial features and not regenerated (so the Up to next does not update for each instance of the pattern):

Example of an Up to next Extrude without Reapply features selected

Pattern a specific feature (or features) listed in the Feature list (an extrude, fillet, sweep, sketch, etc) with Reapply features selected. This is available for sheet metal.

In the following example, the initial extrude was Up to next (bringing the extrude up to the face of the surface). With Reapply features selected, the features patterned (extrude and fillet) are regenerated for each instance of the pattern so Up to next is applied to each instance of the pattern.

Leave material only where geometry overlaps; select the part to pattern, and then Intersect:

Linear pattern: intersect example

  • When selecting a face, edge, or Mate connector (implicit or explicit) to set the Direction, use the Directional arrows Opposite direction arrow icon to flip the result if necessary.
  • When you select a face, edge , or Mate connector (implicit or explicit) for the Direction, you are using the direction that is 'normal to' the face, edge, or Mate connector.
  • When patterning a feature, you are able to select anything in the feature list, in any order. Regardless of the order selected, the features are applied in the order listed in the Feature list.
  • If you select a pattern in the Feature list, you will pattern that pattern, but not the seed. In order to get the seed included, select it as well.
  • When patterning a boolean feature (Boolean, Split, etc), you must also select the features the boolean was applied to.
  • When creating Feature patterns, all aspects of a feature are applied; for example, the end conditions in an extrude feature. (By contrast, Face patterns do not recognize these types of modifiers.)

  • If Reapply features is enabled for the feature pattern, external references will regenerate automatically on a per-instance basis.

    In a sketch, the seed sketch dimensions and constraints to the origin or default plane will not be reapplied. You can use this behavior to scope which dimensions or constraints are reapplied within a pattern:

    • You can pattern sketch features that are dimensioned or constrained to the origin or default planes and choose not reapply those dimensions and constraints.
    • You can also create explicit construction sketches along the default planes or origin when reapplying features along them.

  • If Mate connectors are Part patterned in a Part Studio, they will all be added to the Assembly when the Part Studio is inserted. If you don't see your Mate connectors when the Part Studio is inserted into the Assembly, make sure the Part is listed as the Mate connector owner entity.
