| Detect and Set | Detects and then sets the relations that will be detected during drawing. |
|---|---|
| Parallel | Detection and setting of parallel relations |
| Perpendicular | Detection and setting of perpendicular relations |
| Collinear | Detection of collinear relations. NOTE: No concentric relations are detected during drawing. If you draw concentric objects, on-relations are detected and set between the respective centers. |
| Tangent | Detection and setting of tangent relations |
| Middle point | Detection and setting of middle point relations |
| Detect Only | Settings for relations that will be detected but not set |
| Horizontal line | Detection of horizontal (parallel to the x-axis) line relations |
| Vertical line | Detection of vertical (parallel to the y-axis) line relations |
| Horizontal points | Detection of relations to horizontal points (lying on a line parallel to the x-axis) |
| Vertical points | Detection of relations to horizontal points (lying on a line parallel to the y-axis) |
| On-relation on extension | Detection of potential on-relations. This relation is detected at at a point where two or more objects intersect but at least one of the objects is an extension of an actual object and not the object itself. |
| Select All | Selects all the check boxes in the two areas above. |
| Deselect All | Clears all the check boxes in the two areas above. |
| Detect relations with pointed-to objects only | Detects relations between objects that you point to with the mouse pointer. (They are highlighted). |
| Snap to auto grid | Snaps the Dx and Dy offset values (in the contextual edit bar)
to a system grid, which causes these two values to be displayed
as whole numbers in default zoom mode. When you start a new drawing,
the default zoom factor causes the grid to display the Dx and
Dy offsets as whole numbers — for example, 65.00. (Standard rounding
rules apply.) As you zoom in or out, the grid becomes denser or
rarer, respectively, and Prinect
switches to displaying the values' decimal parts for these values. This behavior applies also during the drawing of rectangles and when you are dragging objects. See examples (in a separate window) of how this functionality works. TIP: If you choose to hide ending zeroes, the values will appear without the decimal part and rounded (Example: 12). |
| Context Toolbar | Here you can choose which helper buttons to see on the contextual edit bar. |
| Show the Detect Relations button | Makes visible the Detect Relation button  ,
from which the detection of relations is managed. |
| Show the snap buttons | Makes visible the buttons serving the snap
functionality  . |
| Show On End button | Displays the button for the on-end relation  . |
