GENERAL USAGE INSTRUCTIONS

------------------------------------------------------------

1. OPEN THE TEMPLATE OR YOUR OWN PROJECT

------------------------------------------------------------

Start with Template.dwg (included) to see a working example, or open your own drawing containing a roadway or utility centerline in Model Space.

The centerline must be a LWPOLYLINE.

------------------------------------------------------------

2. PLACE VP BLOCKS ALONG THE ALIGNMENT

------------------------------------------------------------

Insert the provided VP block at each location where you want a separate plan sheet to be generated (for example, every 450 feet, by station, or at key design points).

Each VP block represents the center location for one PLAN-## sheet.

------------------------------------------------------------

3. PREPARE THE PLAN LAYOUT

------------------------------------------------------------

Use the included PLAN layout from Template.dwg, or create your own layout named PLAN.

The PLAN layout must contain exactly two paper-space viewports (TOP and BOTTOM) that SectionSync LITE will control.

Ensure both viewports are UNLOCKED before running the command.

------------------------------------------------------------

4. RUN SECTIONSYNC LITE

------------------------------------------------------------

In Autodesk® AutoCAD®, type one of the following commands:

SECTIONSYNC_LITE

SSL

Select the centerline polyline when prompted.

The routine will:

• Scan the drawing for VP blocks

• Sort them along the centerline by chainage

• Create or update PLAN-01, PLAN-02, PLAN-03, ...

• Center each viewport on the VP block location

• Rotate views to match the alignment bearing

• Apply viewport scale (preset or VP-controlled)

• Continue numbering from existing PLAN-## sheets

If an odd number of VP blocks exists, the final sheet will use the TOP viewport only.

------------------------------------------------------------

5. OPTIONAL SCALE CONTROL (v1.1)

------------------------------------------------------------

Viewport scale may optionally be controlled using a VP block attribute named:

SCALE

Examples:

• SCALE = 20 -> 1:20

• SCALE = 30 -> 1:30

• SCALE = 40 -> 1:40

If the SCALE attribute is not present or invalid, the routine uses the default preset scale.

IMPORTANT:

• Invisible = Yes

• Constant = No

• Preset = Yes

Changing SCALE affects viewport zoom and CustomScale only.

It does NOT resize the VP block graphic.

------------------------------------------------------------

6. REVIEW THE GENERATED PLAN SHEETS

------------------------------------------------------------

Flip through the PLAN-## layouts and confirm that:

• Each viewport is centered on the correct VP block location

• The view rotation matches the alignment direction

• The drawing scale is correct for each sheet

------------------------------------------------------------

7. RE-RUN AFTER DESIGN CHANGES

------------------------------------------------------------

If the alignment or design changes, move, add, or remove VP blocks and run SECTIONSYNC_LITE again.

Existing PLAN-## layouts will be updated automatically.

------------------------------------------------------------

8. TRIAL AND ACTIVATION

------------------------------------------------------------

SectionSync LITE includes an evaluation trial:

• 5 runs OR 7 calendar days (whichever occurs first)

After the trial expires, activation is required.

To activate:

1) Run:

SSL_ACTIVATE

2) Enter the same email address used during purchase

Once activated, SectionSync LITE will run without further prompts for that user on that computer.

------------------------------------------------------------

The installer that ran when you downloaded this app/plug-in from Autodesk App Store will start installing the app/plug-in. OR, simply double-click the downloaded installer to install the app/plugin. You may need to restart the Autodesk product to activate the app/plug-in. To uninstall this plug-in, exit the Autodesk product if you are currently running it, simply rerun the installer, and select the "Uninstall" button. OR, click Control Panel > Programs > Programs and Features (Windows 10/11) and uninstall as you would any other application from your system.

------------------------------------------------------------

ADDITIONAL INFORMATION

------------------------------------------------------------

SectionSync LITE is designed for roadway, civil-site, and utility alignment projects that require multiple plan sheets along a single centerline.

The workflow is based on VP blocks placed along the alignment in Model Space. The plug-in generates and synchronizes PLAN-## layouts automatically from those locations.
