New/Duplicate command (Edit-Tools menu)
This command can be used to duplicate the currently selected object or polygon. It is only available in Object and Polygon modes.
In Polygon mode, the New/Duplicate command is only available when a polygon is selected. It then has the effect of duplicating the selected polygon, preserving all its properties (texture, ...). The newly created copy is slightly shifted, and is disconnected from all existing polygons so it can be easily moved. In order to facilitate the addition of new track portions, the multiple resolutions are automatically handled : namely, when a high-resolution track polygon is duplicated, copies of it are also created in medium and low resolutions ; when a medium-resolution track polygon is duplicated, a copy of it is also created in low resolution. Therefore, track polygons always ought to be created in high resolution, before their medium and low-resolution versions are merged two by two in order to obtain a smaller number of polygons in medium and low-resolution. Also note the following consequence : the created polygons share the same vertices, so moving the high-resolution version also affects the two lower-resolution polygons created simultaneously, but any change of texture will need to be repeated three times.
Note : The correct procedure to add more polygons to the track structure is the following :
1. Switch to high-resolution view and polygon mode.
2. Select a track polygon reasonably similar to the ones you want to add, in the same track block.
3. Duplicate it as many times as needed using the Duplicate tool.
4. Move all the new polygons around until their general disposition is satisfying. Beware of not flipping a polygon upside down, because the two sides of a polygon are not at all equivalent.
5. Switch to point mode and select the Split/Merge tool.
6. Merge the vertices of the new polygons with the existing frame by successively clicking on an existing vertex and control-clicking on all new vertices to be attached to it.
7. Switch to half-resolution view ; in order to speed up the in-game display, merge pairs of adjacent polygons to form larger polygons (since the Merge tool for polygons has not yet been implemented in this version of T3ED, this is not yet possible : an alternative is to delete some unimportant polygons from the half-resolution view).
8. Repeat step 7 in low-resolution view.
In Object mode, the New/Duplicate command is always available. If an object is selected, then this object is duplicated. The newly created object has exactly the same properties as the original object, and lies at exactly the same place ; the new copy will therefore have to be moved elsewhere.
If no object is selected, the New/Duplicate command attempts to create a new object in the currently selected block. This object initially consists of a single rectangle ; more polygons can later be added by using the Duplicate command in Polygon mode together with the Merge tool in Point mode. Before creating a new object, T3ED displays a dialog box which lets you choose the object type, as well as the texture of the created object polygon.
