GoTo Views now have an optional link to any Multi-Layout Details that were created from them, and can also have their hidden lines removed from the current view.

Linking GoTo Views with Multi-Layout Details
If you use GoTo Views to define your Multi-Layout Details, you can now link your details to your views. When you adjust which layers are included in a GoTo View, either by turning existing layers on and off or by adding new layers or deleting existing ones, and then use the Update option in the GoTo View menu to update the parameters, the linked Multi-Layout Detail updates automatically. You no longer have to use the “Layer Toggle” command in the Multi-Layout/Details menu to adjust which layers are included in the detail. Whether or not GoTo Views are linked to Multi-Layout Details is remembered on a per-drawing basis.

To link GoTo Views with Multi-Layout Details:
  1. Choose Multi-Layout from the Print/Plot menu.
  2. Pick GoTo View from the Multi-Layout menu.
  3. Toggle [S8] Linked on.

When Linked is on, each Multi-Layout Detail in the drawing is linked to the GoTo View that was used to create it. This is a global drawing setting, and cannot be used selectively on just one or some details. Turning Linked off will enable you to update GoTo View parameters without affecting existing Multi-Layout Details.

When you place a Multi-Layout Detail that is linked to a GoTo View, the default detail name has the same name as the GoTo View. Press [Enter] on the keyboard to accept this default name, or type a new name and press [Enter] to proceed. In addition, if you rename the parent GoTo View, DataCAD will automatically rename the linked Detail.

Remove hidden lines in GoTo Views
Using the Hide GTV button in the 3D Hide menu, you can select any GoTo View in your drawing and DataCAD will perform the hidden line removal process on it. A Hide All option is also available to perform the operation on all GoTo Views in the drawing.

The time it takes to perform the operation can be lengthy, so you should only use the Hide All method if there are only a few GoTo Views, or if you are prepared to wait. The [End] key on the keyboard will skip the current view, and the [Del] key will abort the command.

The result is saved as a symbol in the current drawing. During this process, the Symbol Browser automatically set to browse the symbols in the drawing. You may then place instances of the symbols in your drawing. They work just like normal symbols, and may be edited further in the Symbol Editor.

The Hide GTV procedure uses all of the same settings that can be adjusted in the Hide menu. You can use “HLR Partial” to speed up the process, “Pierce” to calculate intersections between surfaces and edges, and “Clip Cube” to recognize the status and position of the Clip Cube. This option is very helpful because the Clip Cube is one of the parameters that are remembered with the GoTo View definition. In addition, the settings in the Hide/Options menu are also recognized by this feature.

If you make changes to the model, you can update the hidden line symbol. The Update Hide option is available in the [Ctrl]+[right-click]/Symbol Tools context menu, or by right-clicking on the symbol in the Symbol Browser. Keep in mind that if you used the Symbol Editor to make changes to the information inside the symbol, those changes will be overwritten by this process.
