After placing a Stair object, you can change the direction of Entities by right-clicking on the object and selecting Edit Stair Object <name> to open up the relevant ‘Edit’ dialog box.

Changing Bidirectional to Up or Down

When changing a Bidirectional stair to either an Up or Down stair, select the appropriate option in the ‘Edit Stair <name>’ dialog box and click OK. Remember to update any Linking parameters that may need to be changed.

Changing Up or Down to Bidirectional

When changing a uni-directional Stair into a Bidirectional Stair, after selecting either Up or Down, the relevant Links tabs will not be available immediately and a message will inform you of this.

To edit the Linking parameters, you need to click OK to close the message and then close the ‘Edit Stair <name>’ dialog. Next, reopen the ‘Edit Stair <name>’ dialog and update the linking parameters as required.

Changing Up to Down or vice-versa

When changing an Up stair to a Down stair or vice-versa, the procedure is slightly more involved as there is an intermediate step which requires you to change the stairs to bidirectional. This procedure works for both cases.

To change an Up stair to a Down stair:

1. Open the Edit Stair <name> dialog.
2. Select the Bidirectional option.

   A message is displayed, informing you that the downward ‘Links’ tab needs to be updated.

3. Click OK to close the message and OK again to close the dialog.
4. Reopen the Edit Stair <name> dialog and select the Down option.
5. Click on the Linking from Bottom tab and set linking parameters as described in Linking methods .
6. Click OK to save your changes.
