If you are working with viewports, it is particularly useful to be able to control layer visibility, veiwport by viewport. IntelliCAD has a viewport-specific control over layer visibility.
The keyboard command is VPLAYER and corresponding alias is VL.
VPLAYER controls the visibility of layers in individual floating viewports. It enables you to make layers that display in one or more viewports invisible in other viewports within the same drawing. The layer control terms freeze and thaw are used to indicate the visibility or invisibility of a layer in a drawing. When you freeze a layer, entities do not display, do not print, and do not regenerate. When you thaw a layer, entities display, print, and regenerate as usual. You can freeze or thaw layers in viewports you have already created, and you can change the default setting for all new viewports you create.
You can also change the visibility of layers in viewports using the Drawing Explorer. Simply click the word Thawed or Frozen to switch between the two settings.
Control over viewport layer visibility is only available for viewports in your active drawing. You cannot change the visibility of layers for viewports in externally referenced drawings.
Before you can use this command, TILEMODE must be turned off (set to zero) and you will have viewports in your drawing’s Paper Space. You must be in Model Space (MSPACE) to select a current viewport.
Controlling Viewport Layer
Visibility When you enter VPLAYER (or VL) your command prompts will appear in the command window (or in a command prompt popup if you have this facility enabled).
List/Freeze/Thaw/Reset/New frozen layers/Default visibility settings: To display a list of all frozen layers in a selected viewport, choose List. To make one or more layers in a viewport invisible, choose Freeze. To make one or more layers in a viewport visible, choose Thaw. To revert to the default visibility setting for one or more layers, choose Reset. To create a new, frozen layer in all new viewports, choose New frozen layers. To set the default visibility for one or more layers, choose Default visibility settings.
To list all frozen layers in viewports – Choose List.
Select a viewport: To list all frozen layers, click on the border of a viewport.
To freeze layers in viewports – Choose Freeze.
Select the layer(s) to freeze: Enter the name of the layer or layers (separated by commas) you want to freeze, or type * to freeze all layers.
All/Select/<Current>: To freeze the selected layers in the current viewport, press Enter. To freeze the selected layers in all viewports, choose All. To freeze the selected layers in one or more viewports you select by clicking on its border, choose Select. To see your changes, use Redraw or Redraw All.
To thaw layers in viewports – Choose Thaw.
Select the layer(s) to thaw: Enter the name of the layer or layers (separated by commas) you want to thaw, or type * to thaw all layers.
All/Select/<Current>: To thaw the selected layers in the current viewport, press Enter. To thaw the selected layers in all viewports, choose All. To thaw the selected layers in one or more viewports you select by clicking on its border, choose Select.
To see your changes, use Redraw or Redraw All.
To reset the layer visibility of viewports – Choose Reset.
Select the layer(s) to reset: Enter the name of the layer or layers (separated by commas) you want to reset, or type * to reset all layers. The layer visibility status (frozen or thawed) will be reset to the default defined with the Default visibility setting option, defined later.
All/Select/<Current>: To reset the selected layers in the current viewport, press Enter. To reset the selected layers in all viewports, choose All. To reset the selected layers in one or more viewports you select by clicking on its border, choose Select.
To freeze layers in new viewports – Choose New frozen layers.
New frozen layer name(s): Enter the name or names (separated by commas) of a new, frozen layer you want to create in all viewports. You cannot enter the name of an existing layer. This layer will also be frozen on all viewports you create after using this option.
To set the default visibility for viewports – Choose Default visibility setting.
Layer name(s): Enter the name of the layer or layers (separated by commas) for which you want to set the default visibility. Doing this sets the default status (frozen or thawed) for the specified layer in all viewports.
Setting Frozen/<Thawed>: To set the default to invisible, choose Frozen. To set the default to visible, choose Thawed. When you use the Reset option, the layer status uses the default setting you choose with this option.
