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.
- Select the cross section.
- 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.
- Select the following contextual function:
- Sweep> Boss.
- Sweep> Cutout.
- The program opens a dialog box.
- 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.
- Preview by clicking the Apply button. If necessary, you can still edit the feature data.
- Select OK.
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.
- Select the boss or cut sweep from the ribbon bar.
- Boss sweep with a cross-section
- Cut sweep with a cross-section
- 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.
- Select or enter the cross-section dimensions if the cross-section has variables or has dimension table data stored in it.
- 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.
- Use the sketch constraints to place the cross-section.
- Exit sketching mode with the context-sensitive function: OK.
- The program opens a dialog box.
- Define the sweep data in the dialog box.
- 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).
