NOTE: By default, the AC3D Layers plugin uses each object's data field to store layer info. This storage does not overwrite any existing data in the object's Data field. See below for more info. This plugin allows you to arrange your AC3D objects into layers, letting you show/hide/select/deselect entire layers at a time. This plugin and code are freely distributable AC3D versions prior to version 5 have not been tested with this script, and should not be used with this plugin.
DescriptionLayers are an additional way of organizing data beyond groups. A layer is simply a collection of groups/objects that you may show/hide/select/deselect as a unit. Selecting/deselecting layers is an additive/subtractive process. This means that if you have some objects selected, then you perform a "deselect" on a layer, only the objects in the layer are deselected - objects outside the layer are left alone. There are 10 layers available.
InterfaceThe layer interface (as shown above in the screenshot) allows you to add objects to layers, or show/hide or select/deselect objects already in layers. Each "row" in the layer interface displays the layer number followed by the number of objects in the layer. This is then followed by layer controls. Controls/elements for each layer are as follows:
Further options include:
InstallationCopy the layer.tcl and layer.p files to your AC3D plugins folder (for example, if using Windows, C:\Program Files\AC3D5\plugin) and (re)start AC3D. You will find the "Layers..." menu item under the "Tools" menu.
UsageAdd objects to layers by clicking the "+" button while groups or objects are selected in AC3D. Once objects are added to a layer, you may show or hide them by clicking the "S" and "H" buttons for that layer, and you may select or deselect them by clicking the "s" and "d" buttons for that layer.
Saving layer dataIf you check the "Save layer info in AC3D data" checkbox on the layers form, the plugin will write layer info to the Data field of each AC3D group/object contained within a layer. This allows you to save layer info with your AC3D document. Layer info is appended to any existing data you may have, so no existing data is destroyed. WARNING: if you need the data element of each group/object to be pure, do not enable this checkbox. NOTE: For most people, this should not be an issue. If you're not sure whether this is an issue or not for your own work, then it very likely isn't. The layer info that is added to the Data field when this option is enabled is the text "//dlayer", followed immediately by a single character. Therefore, if an object's Data field contains the following text:
This is text about my object. blah blah blah. ... and the object is added to layer 2, the text would become: This is text about my object. blah blah blah. //dlayer2 NOTE: Unchecking the "Save layer info in AC3D data" checkbox does not remove "//dlayer#" entries in your Data fields.
Known issuesIf the "Save layer info in AC3D data" checkbox is not enabled, and you delete an object in a layer then "undo" the deletion, the object may not get re-registered as being part of the original layer. You may need to manually add it back.
Advanced options
Checkbox defaultsIf you find yourself wanting the "Save layer info in AC3D data" field to be unchecked by default when the layers window comes up, edit the "layers.tcl" file and change this line: set g_ddhlayer_usedata 1 to: set g_ddhlayer_usedata 0You may also turn off autorefresh by default by changing this line: set g_ddhlayer_autorefresh 1 to: set g_ddhlayer_autorefresh 0 |
