Strata boundaries can either be formed by a series of points drawn on the cross-section or by another strata. Multiple layers can be quickly and accurately drawn by using and existing strata for the their top or bottom boundaries.

 

To select another strata to use for the boundary select Popup > Use Existing Strata or click on the Snap to Existing Strata button on the toolbar. If the current strata has a top and bottom boundary the type of boundary will also need to be selected. The cursor will then change to a hand. Pick the existing strata to use for the boundary using the left mouse button.

 

If the boundary of the existing strata to be used had a lense attached to it, the lense will form part of the new boundary as well.

 

If the boundary has already been specified and contains multiple segments the Create New Segment message will be shown. Select whether to create a new segment or to re-specify the boundary of the existing segment. If you select to use an existing segment and there is more than one segment you will need to select the segment to use.

 

If this is the first time the boundary has been specified the Create New Segment form will not be displayed. \
