Inserting a Dynamic Offset





A Dynamic Offset is a special kind of dimension line with at least one end anchored to another drawing object or survey object. This kind of offset is dynamic because it automatically updates itself as the anchor objects change. Dynamic offsets are used to show lot line setbacks (offsets) on a map.

Make sure you are in Survey Space mode. Dynamic Offsets are not supported in Paper Space.

From the Drawing Settings, Dynamic Offset tab, choose the options you want, including font, color, text height, line type and arrows.

From the Drawing Settings, Line Labels tab, choose the label options you want, including font, color, text height and whether you want either direction or distance labeled or both.

Choose Draw | Dynamic Offset. The cursor will change to a tick (cross) indicating that Drawing View is looking for an insertion point.

Move the cursor to the insertion point and left click. Notice that the status bar displays the location of the tick mark in both survey and paper coordinates. You can also snap on another object to pick the insertion point.

Drawing View draws an offset line from the first insertion point to the cursor. As you move the cursor, the offset line and any line labels are redrawn.

Move the cursor to the end point and left click or snap on an object.

To cancel this command anytime before you finish, press the [Esc] key.

Dynamic Offset Anchors

If you anchor an end of the offset line to another drawing object, the offset line and its labels will change as that object changes. If both ends are anchored to objects, the offset line and labels will change if either anchor object moves.

When you select an object to anchor an offset line to, TPC always looks for either a survey point or survey line. If for instance, you anchor the offset line to a point symbol, TPC will use the survey point for that point symbol instead of the symbol itself. If you select the end point of a survey line, TPC will anchor to the survey point at the end of the line. In this way, you can select the end point of a trimmed survey line and you will get the survey point at the end of the line, not the end of the trimmed line segment.

Moving Dynamic Offset Anchors

When you reposition a dynamic offset anchor, by rotating a traverse or moving a line, the offset line and labels update automatically. You can use this feature to move an object until the dynamic offsets connected to it read the offset you want. This is great way to visually place a house on a lot.

Storing Dynamic Offset Anchors

Offset anchors are stored with the drawing file. When you open a survey file with dynamic offsets, their relationship to their anchors remains intact.

Relabeling a Dynamic Offset Line

Dynamic Offsets labels are based on the drawing’s Dynamic Offset settings. If you change the Dynamic Offset settings of the drawing after you have created dynamic offsets, the properties of the dynamic offsets will change to the current Dimension settings.

Modifying the Properties of a Single Dynamic Offset

To modify any of the properties of a single dynamic offset, right click the offset line or label and choose Properties. TPC displays the Dynamic Offset line dialog box if you selected the line and the Text dialog if you selected the label. Make the changes you want and choose OK. TPC redraws that dynamic offset with the new properties.

TPC knows which properties you modify and holds those properties. However, the properties you do not explicitly change are

Exporting to CAD

If you use a solid arrow for the end caps and a line width greater than zero of your dynamic offsets, TPC shortens the dimension line just enough to end the dynamic offset line with a point.

When you export the drawing to CAD, the dynamic offset line is not shortened, so the point of the arrow may actually be the square ends of the dynamic offset line.
