Example: Edit Coordinates While Creating an Object

When creating an object in a map using a tool such as Create Area, right in the middle of the process we can edit coordinates in the Contents - Record panel's Coordinates tab.   This example shows the step by step process.






We begin with a new, blank drawing open in a window.  As described in the Editing Drawings topic, we choose Create Area for the mode button in the main toolbar.






We click to mark the first coordinate of the area.  The Contents pane switches automatically to the Record panel's Values tab.






We click on the Coordinates tab to show the list of coordinates being built.  The coordinates of the first click appear in blue preview color in the first Coordinates list row.  






Moving the mouse back over the drawing window we can continue to draw the area.






In the drawing window we click the second coordinate location and immediately a second row appears in the Coordinates list.






In the drawing window we click the third location.






Suppose that although we are not yet finished with creating the area, we would like to alter the position of the second coordinate.   We can double-click into the X coordinate box and change the value, pressing Enter when done keyboarding the new value.  If we enter the same X value as the coordinate immediately preceding it, the two coordinates will both have the same X values and thus line up vertically.






As soon as we press Enter to finish editing the vertex moves to line up with the vertex above it.   Suppose now we would like to align the third coordinate to the same horizontal location as the second one.   We double-click into the Y cell for that coordinate and enter the same Y value as the preceding coordinate.  






As soon as we press Enter to finish editing the vertex moves up to the same horizontal, Y level as the preceding vertex.  






If we like, we can specify the location of the next vertex by entering values into the Coordinates list if we prefer that to clicking with the mouse in the drawing window.   We double-click into one of the coordinate boxes in the new coordinate row marked by an * asterisk in the row handle.  






When adding a new coordinate row if we enter just one of the coordinates and press Enter, the system will auto-complete the second coordinate by copying the corresponding value from the immediately preceding coordinate row.  This is a convenient way of adding coordinates that align vertically or horizontally.   In this case, when we enter a Y value for the new vertex...





...as soon as we press Enter, the system will auto-complete the new coordinate row by coping the X value from the preceding coordinate row.   If we do not like that we can, of course, double-click into the X cell and change the value to whatever we want.   Press Add Record to create the area.






We can see that a new, rectangular area object has been created in the drawing.  To confirm the coordinates of the vertices are as we created them, we can Shift-Alt-click the area.






That launches the Coordinates tab of the Record panel to display the coordinates.   Note that the very last coordinate of an area is the same as the first coordinate, to close the area boundary that defines the area object.

Example: Edit Attributes and Move a Point - We look at the attributes for a point in a drawing layer and edit one of the attributes using a more expanded Edit dialog.  We then move the point to a new location. Easy!

Example: Edit Covered Objects - Working with drawings where some areas completely cover smaller areas is a bad idea, but sometimes we have to work with data in that form whether we like it or not.   This topic shows techniques that can help us select and edit objects that are completely hidden by higher objects.
