Grouping Traverses





Traverse Groups allow you to group similar traverses together in the Traverses Manager. Each group has a unique group name and can have any number of traverses in it. TPC supplies some initial groups for you like Alignments, Boundaries, Lots, Control, Imported and others plus you can add your own.

Once your traverses are in groups, you can rearrange the groups, expand or collapse them (Windows 7/Vista only), hide or show them, or select the group name and all the traverses in it are selected automatically.

Organizing your traverses into groups is all about making it easier to manage your survey data.

Displaying Groups

To display groups choose Tools | Traverse Groups | Show Groups. This a toggle, so selecting it will either turn groups on or off.

In this screen shot, we've turned groups on and collapsed all but the Parking group.

Moving Traverses Into Groups

To place traverses into a group, select (highlight) the traverses you want in the Traverses Manager, then choose Tools | Traverse Groups | Move Selected Traverses to Group. TPC displays the Traverse Groups dialog. The dialog title will say, Move 3 traverses to a group indicating that you have selected 3 traverses. The number will change to reflect the number of traverses selected upon entering the dialog.

Select an existing group from the list or type in the name of a new group (TPC will ask if you want to create the new group) then choose OK. TPC will place the selected traverses into the group and re-display the Survey View.

Group Sequence

Traverse Groups are displayed in the Traverses Manager based on their group sequence. You can change the sequence by moving groups up or down one group at a time or sending them all the way to the top or bottom of the view. You will probably use group sequence in conjunction with Collapsing or Hiding groups as explained below. Combining these group tools makes working with lots of traverses a breeze.

Managing Groups

To manage groups, choose Tools | Traverse Groups | Edit Groups... Or you can choose Tools | View | Format View then select the Groups tab. TPC displays the Traverse Groups dialog. Here are some of the things you can do with groups, all of which are described in more detail in the Traverse Groups dialog.

Change the Group Name Alignment

Group names can be aligned Left, Center or Right in the Traverses Manager.

Change the Group Sequence

You can move groups up or down in the list or move a group to the top or bottom of the list. The list determines the sequence used to display Traverse Groups in the Traverses Manager.

Add New Groups

Add a new group just by typing its name. TPC asks if you want to create the new group and inserts it at the bottom of the list.

Delete Existing Groups

You can delete any group that does not contain traverses. TPC supplies a default list of groups. If it includes some groups you are not likely to use or if you don't like the group names we've used, just delete them.

Save Your Group List as the Default

Each new survey you start reads from a default list of group names. These are your starting groups for the survey. Once you start using groups and settle on the group names you want to use, save your list as the default.

Collapsing Groups

You can collapse and expand groups. Collapsing a group hides any traverses in the group but leaves the group name displayed in the Traverses Manager. A small chevron (V) to the right of the group name indicates whether the group is expanded (points up) or collapsed (points down). Clicking on the chevron expands or collapses the group.

This convention is used throughout Windows Vista. Just open Explorer and choose View | Groups. You'll see what we mean.

Commands related to collapsing groups can be found in the View | Traverse Groups | Collapse / Expand Groups pop-up menu.

Collapse / Expand Commands

Collapse This Group - collapse just the selected groups.

Collapse All Groups But This - collapse all groups except the selected on. If more than one traverse is selected, only the last traverse selected is left expanded.

Collapse All Groups - collapses all the groups. You can then expand groups as needed using the chevron (V) to the right of the group name.

Expand All Groups - expands all the groups.

Hiding Groups

You can hide groups. Hidden groups do not display the group name in the Traverses Manager. You can turn groups on and off in the Groups dialog by checking the group name in the list. Groups without a check mark in the box are hidden.

Other Hide / Show commands are:

Hide This Group - hides this group so that it is no longer visible in the Traverses Manager.

Hide All Groups But This - hides all the other groups, leaving the selected group visible.

Show All Groups - show all the hidden groups again in the Traverses Manager.

Selecting Traverses via Groups

You can select all of the traverses in a group by selecting the group name. Just left click a group name and watch as all the traverses in the group get selected automatically. You can then right click the group name and select an operation to perform on all the traverses in the group.

This is handy for tagging and untagging traverses as a group. Once the group has selected all the traverses, just click the check box next to the traverse name to tag or untag all the traverses in the group.

Using Groups in Dialogs

Dialogs that list the survey's traverses (like the Offset to Alignment dialog)) take advantage of groups to help you select the traverse you want more easily. These traverse lists include the Traverse Groups along with each traverse. You can select a Traverse Group in the list to expand the group and show the traverses in that group. This makes it easy to pick the traverse you want.

Creating Traverse Layers with Groups

You can also use traverse groups to create Traverse Layers in a drawing.  See Traverse Layers.

For example, all the traverses in the Parcels group can go on a Parcels layer or you can further stratify those layers as Parcels_TpcLines and Parcels_TpcFills.
