Splitting long and tall profile views
A profile view too long for one sheet is cut into one piece per sheet, each sized to its sheet's station range, carrying its bands, pipes, structures and pressure networks. A profile too tall for its viewport is split vertically as well: cut into segments, each drawn from its own datum, laid out as a row in the profile viewport, at the scale you chose. The split runs in the source drawing that holds the original profile views; the sheets live in a separate layout drawing, and the two are kept in step from either side.
Before you start. Profile Split spans two drawings. The splits are created in the source drawing, the one holding the original profile views with no built layouts. The sheets live in the layout drawing. Save each drawing after working in it, so the other one can read the change.
Splitting a long profile view
A long profile view is cut into one piece per sheet, each covering that sheet's station range. The work starts in the source drawing.
Step 1. Open the source drawing: the one holding the profile views, with no built layouts. The drawing support section on the Welcome tab only appears there.
Step 2. Press Profile Split to open the Profile Split tab, then press Profile Split on that tab.
Step 3. Pick the alignment, then pick the layout drawing: the one you have already built your sheets in with SheetAgent for Civil 3D, not any drawing. Then pick an anchor point in model space. That point is the top left of the split row.
Step 4. A cyan preview appears with an accept or pick-again prompt. Accept to commit, or pick again to reposition.
Step 5. One split profile view is created per sheet, each sized to its tile's station range. Bands, pipes, structures and pressure networks all come along.
Step 6. Save the source drawing so the layout drawing can read the new splits.
Step 7. Open the layout drawing and finish it either way: press Split Profile View on the Multi VP tab, or open Health and press Profile Sync. They do the same thing, and each sheet's profile viewport ends up pointing at its own split.
Splitting a profile view vertically
A profile that is taller than the profile viewport at your scale used to mean one thing: a smaller scale. From 2.4.1 there is a second answer. The profile is cut into segments, each drawn from its own datum, and the segments are laid out as a row inside the profile viewport, so the whole elevation range fits at the scale you chose.
Step 1. On the Multi VP tab, set up Plan and Profile as usual and press Create Preview. When the profile height does not fit the viewport at the chosen profile scale, the Scale Check dialog offers two buttons: Change to 1:X, which bumps the scale so the whole profile fits, or Split profile vertically, which keeps your scale.
Step 2. Choose Split profile vertically. The Plan Coverage dialog asks how much of the viewport height the plan should take: share the sheet half and half, or set the plan coverage width in model units. The plan tiles are cut to what the profile covers at that scale.
Step 3. Finish the preview. The layout drawing must be saved, and the profile's source drawing must not be open anywhere else. SheetAgent for Civil 3D saves the layout and opens the source drawing, where the split is made. If the profile is local, it stays where you are.
Step 4. Pick the anchor point, the top-left corner of the split row. A cyan preview draws every segment with its seam station and its datum, and the command line counts the sheets, views and seams. A segment that cannot fit reads OVER; see When a segment reads OVER.
Step 5. Accept, Move or Pickagain. Move lets you click a seam and drag it to another station. Pickagain takes a new anchor. Accept creates one profile view per segment, laid out as a row.
Step 6. Choose Save and complete the layout. The source is saved, the layout comes back, the sheets are built and the profile tiles are synced onto the split views. If you would rather adjust the views first, choose I will adjust first; when you are done, save the source, return to the layout, press Build Sheets, then Sync to Layout. Closing the source without saving drops the split.
Where the seams and datums land
Height is the master input. Your scale stands; the profile viewport height at that scale fixes the height every segment can show, and the split absorbs the rest.
As few segments as the height allows. Each segment runs as far as the profiles fit under its datum, so the count is the minimum. At every station the envelope is the lowest and highest of all the profiles drawn in the view, existing ground included.
A seam lands on a grade break of the layout profile where one is in reach, else on a round station (every 50 ft, or 20 m), else exactly where the height ran out. A seam keeps 25 ft (10 m) clear of a plan match line, and every plan match line is a fixed boundary of its own. No segment is shorter than 50 ft (20 m).
Each datum is the lowest line in the segment, less the padding your profile view style already has below the line, rounded down to a whole foot (half a metre). The padding above and below comes from the unsplit view's style; the split adds none of its own.
The original end-to-end range of the profile view is kept.
When a segment reads OVER
A station where the drawn profiles need more height than one segment can show is reported, not fixed. In the preview that segment reads OVER, and the tally counts it. No seam can fix it, and the scale is never changed behind your back: the line is clipped at the top of that segment.
Your options: accept it as drawn; move a seam so the tall stretch shares a segment with less; or run the preview again at a smaller profile scale. Which one is right depends on what the reviewer needs to read there.
Adjusting a vertical split after the build
Seams and datums can be adjusted without starting over.
Step 1. In the source drawing, on the Welcome tab, press Vertical Split Finetuning. It is enabled only when the drawing holds a vertical split, the drawing must be saved, and it is not available in a Project Control drawing.
Step 2. The preview appears over the existing views. Seam slides a seam; click the start or end of a sheet's window instead and a new seam is added beside it, sliding while the end holds. Vertical slides a segment's window up or down, for a line that sits too close to the top or the bottom; that datum is yours from then on and survives later updates.
Step 3. Accept. The split views are re-created and their labels synced. If the layout is open, choose Save and complete the layout; otherwise save the source, open the layout, and press Profile Sync on Health so the sheets show the adjusted views.
When the plan tiles change later, Health raises the same warning as for a split per sheet, and the same two routes settle it. See When the tiles change after a split.
To go back to the original profile view, open Health and press Revert Split: the split views SheetAgent for Civil 3D created are erased, every sheet points at the original view, the profile tiles move onto it, and Update Sheets runs.
Split Profile View does nothing
Split Profile View re-points each sheet's profile viewport at its matching split. It does not create the splits, so it only has something to do once they exist in the source drawing.
If pressing it changes nothing, run the split in the source drawing first and save that drawing, then press Split Profile View again.
If it still changes nothing, the build is not plan and profile, so there are no profile viewports to re-point.
Splits that have fallen behind the sheets also show on Health as a profile sync warning.
When the tiles change after a split
If the plan tiles change after a split, the splits no longer cover the sheets and Health raises a warning. Settling it is one press, or you can do the same work by hand.
Step 1. Save the layout drawing.
Step 2. Open Health and press Open Profile Source. You are offered two routes: Assign to SheetAgent, or Do it manually.
Assign to SheetAgent is the short one. It opens the source drawing, updates the splits, comes back and syncs, without you moving between drawings yourself.
Do it manually leaves the same work to you: in the source drawing press Sync to Layout and save it, then back in the layout drawing press Split Profile View on the Multi VP tab, or Profile Sync on Health.
Either route re-creates the splits to match the current tile coverage, reusing the alignment, source profile view, anchor and row gap from your original split. The warning clears until the tiles change again.
Moved profile tiles
A warning that profile tiles moved on a number of sheets means they were moved in model space while placement is automatic. In automatic mode, Update Sheets returns them to the computed positions.
To keep your own layout, open Health and press Accept Profile Positions. Placement becomes manual: updates preserve your positions, and the profile viewports follow the moved tiles.
To discard the moves instead, press Update Sheets and the tiles return to the computed positions.
While placement is manual, Retile leaves the profile positions alone. There is no switch back to automatic placement: returning to it means resetting the project and rebuilding.
