Appearance
Why is it here?
Fablnx places every grid line and every beam end from what the drawing says. The Why view shows where each one came from, what is still open, and lets you correct it.
Open it from the scene editor's head bar with Why is it here?. If you opened it from an item, the view selects that item and frames it on the sheet.
Solve the sheet
Fablnx places a plan when you detect on it, when you push it, and when you ask. To ask, press Solve, in the Why view or in a plan's editor head bar. It solves the whole sheet. The button itself says where the answer stands; hover it for the full sentence.
| The button says | Meaning | Pressing it |
|---|---|---|
| Solve | Not solved yet, or solved only part of the way | Solves the whole sheet |
| Solved | The answer is for the sheet as it is now | Solves it again |
| Solve again | You changed the sheet since, or the last solve failed (the reason is in the tooltip) | Solves it again |
| Solving… | A solve is running; the view updates when it ends | — |
To solve only part of the way, for example the grid alone, ask the copilot.
The head of the view is one row: the sheet's name, the colour modes, Solve, an icon, and the push button, which says Push or Push blocked · 1 (hover it for what must be fixed). In a browser, where there is no push, a chip says the same (Push blocked · 1, Ready to push, Checking…). The icon opens the sheet in the editor. Everything else sits above the lists on the left: the counts, as small chips, and What the colours mean, folded until you open it, in the same words.
What blocks the push is the first group under Open questions — Blocks the push to Tekla — each with what to do about it and the sheets it names by number; click one to see it on the sheet. On an elevation, ends placed by nothing are counted when they look alike (18 × 2L6X6X1/2 brace · both ends). Check again asks once more after a change. The plan and the elevation views use the same title, list names and layout.
What you click opens on the right. Drag the inner edge of either side panel to make it wider or narrower; each keeps its width. Both side panels fold the same way: the fold button in the panel's own corner tucks it into a slim strip at the edge (Lists on the left, Details on the right), so the drawing gets the room; click the strip to open it again. A card says in one sentence what state the item is in, and its lists say what placed it and what it holds up. Each action has one button; tick Put it in my draft instead to collect them in a draft. A brace line is shown by its two end points, not as a line across the sheet.

The head of the view counts Members, Ends (by where they come from), Grid lines, islands and open questions.
Colour by changes what the colours on the sheet mean. A key below the counts says what each colour is.
| Colour by | Shows |
|---|---|
| Source | Where each end comes from: Pinned by a person, Fact: the drawing says so, Near-fact: read off the grid, Assumed: a working point, Estimate: where the ink is, Not placed. |
| Joints | One colour per joint. A member shows one band per connection: a column, a member's body, ends that meet, a grid crossing, or nothing. |
| Missed joints | The same, plus the places where the ink touches but the solver was not told. |
| Islands | Groups of grid lines that nothing ties to the rest. |
Click anything on the sheet to open its card on the right. Wider drawing hides the lists; Show the lists brings them back. Open this sheet in the editor goes back to the scene.
Open questions
What is left for a person to answer, grouped as Blocks the push, To check, For the owner to decide and Assumed. Click one to see what it names on the sheet.
Grid order
Rounds lists each step that tied a loose group of grid lines in, and which lines it placed. Islands lists each loose group and the ties that could place it. Click Confirm to accept a tie or Reject to rule it out.
Facts
Everything the solver was told about the sheet. Filter by stage, by Who said it (The rules, People, The AI, Imported) and by In use or Set aside. Show more loads more. History → Show lists every change, who made it and when; Older and Newer page through it.
The card for an item
The card names the item and its state, and lists:
- Placed by — what put it where it is.
- Stands on — what it rests on.
- Holds up — what rests on it.
- Flagged — its open questions.
- What you can do — the corrections that apply. Click one to say it now, or add to my draft to collect several and see their effect first.
You can also ask the copilot about the item from the card.
Drafts
A draft is a set of corrections that has not been applied. Your draft and the AI's (Suggested by the AI) appear in a bar above the sheet.
- Remove an entry with its × if you do not want it.
- Pick a stage and click Preview. Fablnx solves the sheet with the draft and shows the change: member counts before → after, what changed and what moved (in inches). Show them on the sheet highlights those items.
- Click Apply to make the corrections, or Discard to drop the draft.
Nothing the AI suggests changes the sheet until you apply it. Your own word outranks the AI's: reject its statement, or pin the end yourself.
Inside Tekla
Two more controls appear in the Fablnx app:
- Use what the Tekla model knows — shows the answer with the open model's members taken into account.
- Push to Tekla — pushes this sheet to Tekla. It says what it would do before anything is written.
Read an elevation
On an elevation the view is called Why things are where they are. Each member end is placed where one of the sheet's grid lines crosses a level or a slant line. An end that no two lines cross is shown where it is stored, and counted as placed by nothing.
- Open what the sheet says for the counts.
- Everything, Grid lines or Members chooses what is drawn.
- Hover a member to see where each end comes from.
- The Questions and Members lists, and Details, work as on a plan.
