Sweep

Prerequisites for the function

  • The part model has a cross-sectional feature that is used for sweeping if you use the context-sensitive function Sweep.
    • Cross Section
    • The cross section is not needed if you use the ribbon bar functions, because then the cross section is fetched from the library.
  • The part model has either an edge line or a guide curve that is used to control the sweep.
  • The cross-section must be able to curl along the guide curve in such a way that it does not rotate around itself in any part. Note this:
    • When modeling a guide curve and its roundings.
    • When modeling a cross-section and its location on the guide curve.

Add a sweep with the context-sensitive function

  • The context-sensitive function should be used when the model already has a cross-section and a guide curve.
  1. Select the cross section.
  2. Select the guide curve for the cross section as follows:
    • Select the lines functioning as a guide curve one by one by pressing Ctrl+left mouse button.
    • Select only one line from a tangential polyline.
  3. Select the following contextual function:
    • Sweep> Boss.
    • Sweep> Cutout.
    • The program opens a dialog box.
  4. Define the sweep data in the dialog box.
    • Add lines to a guide curve by clicking the Add button.
    • In special cases, select: Keep cross section direction.
      • Normally, the cross-section is positioned perpendicular to the guide curve at every point.
    • Trim the end of the sweep to an element selected from the model, if necessary.
    • Shorten the sweep in the direction of the polyline with the Offset value.
    • A boss sweep can also act as a tool.
  5. Preview by clicking the Apply button. If necessary, you can still edit the feature data.
  6. Select OK.

Sweep Feature Data

Note:
  • You can add lines to a guide curve by editing the sweep data. Click the Add button in the Sweep elements of the dialog box, and select lines one by one or a tangential line chain.
  • Edit the cross section of the sweep by selecting the cross section to be edited from the feature tree and the context-sensitive function Edit Sketch. You can also edit the guide curve by selecting it.

Boss sweep with the ribbon bar function

  • You should use the ribbon bar functions when you use the cross-sections stored in the profile library for the sweep.
  1. Select the boss or cut sweep from the ribbon bar.
    • Boss sweep with a cross-section
    • Cut sweep with a cross-section
  2. Select the cross section from the profile library
    • Either from the cross-sections added to the Standard directory by the software supplier.
    • Or from the profile cross-sections saved in the Own directory by the customer.
  3. Select or enter the cross-section dimensions if the cross-section has variables or has dimension table data stored in it.
  4. Click the location of the cross-section on the guide curve or the edge line of the part.
    • Before clicking, you can use the functions of the auxiliary menu to rotate or mirror the cross-section.
  5. Use the sketch constraints to place the cross-section.
  6. Exit sketching mode with the context-sensitive function: OK.
    • The program opens a dialog box.
  7. Define the sweep data in the dialog box.
  8. Select OK.

Example: Groove to the edge lines of the part

  • A cross-section and one edge line have been selected from the part. Due to rounding, the edge line continues tangentially around the entire part.
  • Context-sensitive function: Sweep> Cutout.

Example: Spring

A cross section is swept along the spiral guide curve, adding material.

Example: Thread groove

A cross section is swept along a spiral guide curve, cutting out material.

Example: Deselect unnecessary lines from the guide curve

  • A cross-section and guide line have been selected from the model (image at the top left).
  • Context-sensitive function: Sweep > Boss.
  • In the Sweep Elements section of the dialog box, all unnecessary lines have been removed by selecting the line and the Delete button. (image below on the left).
  • P

Example: Accept all tangential guide curve lines

  • A cross-section and guide line have been selected from the model (image at the top right).
  • Context-sensitive function: Sweep > Boss.
  • The program searches for all lines tangential to the guide line (image at the bottom left).
