Selection
At any given time, the editor will always have a selection. The selection describes the current target of most editing actions. Thus, there will always be exactly one of each of the following:
- A selected segment
- A selected side, one of the sides of the selected segment
- A selected line, depending on the selected point
- A selected point, one of the points of the selected side
- A selected object
In addition, for every kind of selection, there is a corresponding kind of secondary selection, called the "other selection". That means that the exactly one of each of the following also exist:
- An "other segment"
- An "other side", one of the sides of the "other segment"
- An "other line", depending on the "other point"
- An "other point", one of the points of the "other side"
- An "other object",
Actions which by their nature require two selections will use the current selection as the primary selection and the "other" selection as the secondary selection. Both selections will be highlighted in the mine view as follows:
| Selection Mode | Point Mode | Line Mode | Side Mode | Segment Mode | Object/Block Mode |
|---|---|---|---|---|---|
| Selection |  |
 |
 |
 |
 |
| "Other" |  |
|
|
|
|
| Neither (w/ lines) |  |
|
|
|
|
| Neither (w/o lines) |  |
|
|
|
|
Key points of the selection highlights:
- Selected line/point is yellow, selected side green and selected segment white
- If the selection mode is point/line/side/segment, the corresponding selection is red instead
- The other selection looks the same regardless of the selection mode
The selected object will have a yellow ring around it and the "other object" will have a red ring around it.
There are six selection modes, and the current actions taken depend on the selection mode.
- Point Mode: The user can select a point by clicking, but cannot switch to another segment that way. Movement actions will only move the selected point.
- Line Mode: The user can select a line by clicking, but cannot switch to another segment that way. Movement actions will only move the selected line.
- Side Mode: The user can select a side by clicking, and can switch to another segment that way. Movement actions will only move the selected side. This is the default mode.
- Segment Mode: The user can select a segment and side by clicking. Movement actions will only move the selected segment.
- Object Mode: The user can select an object by clicking. Movement actions will only move the selected object.
- Block Mode: The user can select a segment and side by clicking. Movement actions will move everything that has been marked.
