View and arrange a schematic without changing circuit connectivity

Keep the netlist as the electrical source

The visualizer draws parsed component blocks and connections. Moving or rotating a block changes the drawing; editing the netlist changes circuit connectivity or values. Editing an exported PNG/SVG does not update the circuit. Use the complete source and current numerical report when deciding what the circuit does.

Use a compatible licensed JoSIM®-Pro 2.9 GUI. This guide checks a frozen maintained Windows candidate, not every final distributed package. Save dependent includes explicitly before preparing the view. The visualizer has a separate parser from simulation and static editor analysis; success in one route does not prove success in another.

Extract the complete small hierarchy

The three-file download contains main.cir, filter.cir and quoted-include.cir. Open main.cir for the supported teaching route and keep filter.cir beside it. V1 drives IN with a 1 mV pulse; X1 instantiates FILTER between IN and OUT; RLOAD is 20 ohms. The cell contains R1 = 10 ohms and C1 = 1 pF.

quoted-include.cir is an explicitly labelled counterexample for KB-SCHEM-001. Its quoted include runs successfully but the exercised Windows visualizer rejects the quotes as path characters. main.cir uses the adjacent unquoted filename filter.cir, which has no spaces. Do not strip required quoting from arbitrary real-project paths. Preserve the simulation-valid source and use an appropriate complete viewing copy when needed.

Open and arrange the root schematic

1. Open main.cir, then choose the visualizer/Schematic toolbar action. Confirm that MAIN contains V1, X1 and RLOAD. Imported numerical-result tabs contain no netlist to visualize.
2. Select RLOAD. Arrow keys move the selected block by a grid step; Shift+arrow uses a larger step. R and Shift+R rotate in opposite directions. Pointer dragging and pan/zoom are described by the manual, while this native check exercises accessible selection and the actual keyboard handlers.
3. Use Ctrl/Cmd+Z and Ctrl/Cmd+Y for visualizer layout undo/redo. The check moves RLOAD by one 20-unit grid step, rotates it by 90 degrees, undoes both operations and redoes both.
4. Use the grid controls or G to change grid style. Ctrl/Cmd+0 resets the view transform; it does not remove the saved component layout. Read full component expressions in the source rather than relying on an abbreviated diagram label.

Navigate and save a child scope

Do not manually edit the encoded SCHM blocks. They are layout data carried as comments, not circuit elements. Cosmetic changes still modify the file and require Save. In KB-SCHEM-002 the normal modified flag and Save action work, but the layout-only dirty classifier remains false; do not rely solely on a cosmetic label to decide what changed.

1. Open the X1 subcircuit block. The view changes to MAIN > FILTER with R1 and C1. The normal double-click/Enter action enters a resolved subcircuit; the check uses the product’s accessible open action.
2. Arrange R1 in this child scope. The check uses Shift+Down and reverse rotation. Back, Backspace or Alt+Left returns to the parent; MAIN and FILTER keep independent named layout payloads.
3. Save the netlist explicitly. In this example both SCHM_MAIN and SCHM_MAIN__FILTER tagged comment blocks are written into main.cir, the active host deck; filter.cir remains unchanged. Do not expect the included cell definition to receive the drawing metadata.
4. Close and explicitly reopen the saved source in the intended app process, then enter the desired scope again. The checked second process reconstructs both layouts and reproduces both vector exports byte for byte. This is explicit saved-file reopening, not automatic GUI-session restoration.

Export the intended scope after saving

KB-SCHEM-003 reproduces a changed-child export resetting to the root: after a child layout edit, export rebuilds the visualizer and produces the MAIN diagram. A file existing is insufficient proof that the requested child was exported. Saving and re-entering FILTER without another layout edit recovers the correct child SVG.

The exported PNG/SVG is built from the prepared scene and excludes application chrome. The reference images in this guide show the actual native controls instead. A missing output directory was refused; retrying in the existing export directory produced the intended file.

1. Save the layout, return to Source and reopen Schematic. Re-enter the exact child scope you intend to export. Confirm its visible scope label and component names.
2. Use the schematic export toolbar action. Choose PNG image for raster output or SVG vector schematic for scalable output, and select an existing writable folder. The selected filter supplies a missing extension. The native checks exercise the production writers; physical OS picker input is not qualified.
3. Inspect the actual new file. MAIN should contain V1/X1/RLOAD; FILTER should contain R1/C1. If the wrong scope appears, repeat the save/reopen/re-enter sequence and export to a new destination.
4. Keep the relevant source revision and scope name with the figure. Use plot export for waveforms or numerical traces; the toolbar chooses its workflow according to the active view.

Distinguish a cosmetic edit from a changed circuit

Every electrical statement in the teaching source remains unchanged through move/rotate/Undo/Redo, hierarchy layout and explicit save. Four fresh simulations—quoted include, supported include, saved arranged deck and reopened arranged deck—produce exactly equal time and trace arrays: 101 samples and two voltage traces each.

That equality checks this cosmetic transformation; it does not establish general physical accuracy, timestep convergence or correctness of an arbitrary diagram. The synthetic RC example is not customer data or a device validation.

A deliberate RMON addition rebuilds the scene with a fourth root component and invalidates the prior numerical result. Restoring the intended source and rerunning produces the original arrays. Refresh/reopen the schematic after semantic source changes and require current results before interpreting a plot.

Recover from a visualization failure

Scope of the checks

Twenty-seven independent checks cover two normal Windows app processes, 12 matching maintained GUI sources, three complete inputs, decoded root/child layout payloads, layout undo/redo, explicit save, SVG/PNG artifact validity, export scope/recovery, parser rejection/recovery and exactly equal current numerical arrays. Three reproduced limits remain tracked without product fixes.

Physical pointer/picker interaction, arbitrary include grammar/component rendering, external schematic import or electrical editing through the diagram, automatic tab/session restore, other platforms and final packages remain unqualified. The previous manual-only image was replaced by the checked native teaching view; its original reference remains preserved privately.
