Editing paper space viewports

Setting the layer properties in a paper space viewport

The layer visibility can be controlled per paper space viewport. When working in a paper space layout, a number of VP* (Viewport) properties are available, which affect the current viewport only and can be adjusted from the corresponding default properties:

  • VP Freeze
  • VP Color
  • VP Linetype
  • VP Lineweight
  • VP Transparency
  • VP Plot Style
  1. Double-click inside the paper space viewport.
  2. Launch the EXPLAYERS command.

    The Drawing Explorer / Layers dialog box appears.

  3. (option) Click the icon in the VP Freeze column to toggle the display of a layer.

  4. (option) Click the icon in the VP Color column, then select a color in the Select Color dialog box.

  5. (option) Click the VP Linetype column, then select a linetype in the drop-down list.

  6. (option) Click the VP Lineweight column, then select a lineweight in the drop-down list.

  7. (option) Click the VP Transparency column, then select a transparency value in the drop-down list.

  8. (option) Click the VP Plot Style column, then select a plot style in the Select Plot Style dialog box. This option applies to STB (Style Tables) drawings only.
Note:
  • When the Indicate layers in use option in the View menu of the Drawing Explorer dialog box is set, the icon in the Current column indicates whether VP property overrides exist.
  • Use the Viewports / Vpfreeze option of the LAYOFF and LAYFRZ commands to freeze layers in a viewport by clicking entities.

Clipping a viewport

The VPCLIP command (short for "viewport clipping") clips viewports in layouts.

Only circles and closed polylines can be used to create a clipped viewport. Therefore, use the Create polyline representations of an ellipse option of the PELLIPS system variable when creating an elliptical viewport.

Removing the clipping boundary of a viewport

The Delete option of the VPCLIP command removes the clipping boundary.

Rotating the display in a paper space viewport

The display of a paper space viewport can be rotated only if the display of the viewport is not locked.

The Align > Rotate option of the MVSETUP command defines the angle of the content of a viewport relative to the X-axis of the world coordinate system (WCS).

If the VPROTATEASSOC system variable is ON, the ROTATE and MANIPULATE commands rotate the content of a viewport over a specified angle. The viewport is clipped by a rectangle of the dimensions of the original viewport. Use the Delete option of the VPCLIP command to remove the clipping.

In order to undo the rotation:

  • Set the rotation angle = 0 (zero) in the Align > Rotate option of the MVSETUP command.
  • Double-click inside the viewport, then launch the PLAN command and press Enter twice (= set plan view of the WCS).

Aligning viewports

  1. Launch the MVSETUP command.

  2. Choose Align in the prompt menu.

    You are prompted: Enter an option [Angled/Horizontal alignment/Vertical alignment/Rotate view/Undo]:

  3. (option) Choose the Horizontal alignment option.

    You are prompted: Specify basepoint:

    • 1. Pick a point in the reference viewport.

      2. You are prompted: Specify point in viewport to be panned:

    • 3. Pick a point in the viewport to be aligned.

      4. The display in the viewport is moved vertically to align the two points horizontally.

  4. (option) Choose the Vertical alignment option.

    You are prompted: Specify basepoint:

    • 1. Pick a point in the reference viewport.

      2. You are prompted: Specify point in viewport to be panned:

    • 3. Pick a point in the viewport to be aligned.

      4. The display in the viewport is moved horizontally to align the two points vertically.

Aligning model space and paper space points

The ALIGNSPACE command adjusts viewport angle, zoom factor, and pan position based on alignment points specified in model space and paper space.

Aligning 1 point

  1. Launch the ALIGNSPACE command.

    You are prompted: First alignment point in Model space:

  2. Click inside a layout viewport, then pick a point.

    You are prompted: Second alignment point in Model space or <Return> for none:

  3. Right-click or press Enter.

    You are prompted: Alignment point in Paper space:

  4. Pick a point in the layout.

    You are prompted: Activate the viewport which will be used for alignment.

  5. Click inside the viewport you want to align.

  6. Right-click or press Enter to confirm.

    The display in the selected viewport is moved to make the two points coincident.

Aligning 2 points

  1. Launch the ALIGNSPACE command.

    You are prompted: First alignment point in Model space:

  2. Click inside a layout viewport, then pick a point.

    You are prompted: Second alignment point in Model space or <Return> for none:

  3. Pick a second point in the layout viewport.

    You are prompted: First alignment point in Paper space:

  4. Pick a point in the layout.

    You are prompted: Second alignment point in Paper space:

  5. Pick a second point in the layout.

    Prompts you: Activate the viewport which will be used for alignment.

  6. Click inside the viewport you want to align.

  7. Right-click or press Enter to confirm.

    The display in the selected viewport is moved, rotated and/or scaled to make the points two by two coincident.
