v1.0.2

CurrentReleased：2026-10-19

The drawing check gains Check items: what the product cannot decide is checked one by one, with who checked it and when kept on record (plus a check before sending and an internal check record). Floor plan drafts show concession cards when the wishes do not all fit. Floor plans gain "Create from conditions", illustration-style reference 3D and 21 flyer templates.

Drawing check: check items

The Checklist tab is now Check items. What the product cannot decide (company rules, information outside the drawings, design judgement, findings to be confirmed) is listed with why to look, what to look at and where; mark each one Checked, Not applicable or Make it a finding. Who checked it and when stays with the project.
For findings to be confirmed, Checked means confirmed in-house and not sent to the outside designer; Make it a finding puts it in the report. If nothing is chosen, it goes in the report as before.
If unchecked items remain when you make the findings report, you are told before sending: check them first, or write a reason and send anyway (the reason is kept in the internal check record).
On revised drawings, items whose content has not changed carry over the previous result; only items whose drawing or content changed are to be checked again.
Enter confirmed values: site area, the difference between design GL and average ground level, the regional classification, the width of the road in front and the window-head heights on the first and second floors; the latest submission is checked against them again. Standard window heights can be set in the company pack.
Export an internal check record (PDF, A4 landscape), separate from the findings report sent to the outside designer.
For a mismatch between two drawings, both drawings can be viewed side by side.

Floor plan drafts: wishes and concessions

Plan-draft conditions are now split into the customer's wishes and what cannot change (law and site). Any wish can be marked as not to be given up, and the LDK and total floor area can take an acceptable limit. In Create from conditions, choose what may be given up if it does not fit (parking, floors, Japanese-style room, number of rooms).
Concession cards: when no draft meets every wish, the result of giving up each wish one at a time is shown on cards (number of drafts, thumbnail, what is kept and what is lost). Rebuild with the conceded condition in one step; in plan drafts you can also add a card's draft to the list.
Concession strip and before/after: right under the result, one line shows which concessions yield drafts (for example "Make it 2LDK (wished 3LDK): 5 drafts"), and See the concession options ↓ jumps to the cards. After Remake with this condition, the draft before and the current draft are shown side by side (thumbnail and key points) with the condition changed and what changed (for example "Parking 1 → Parking 0").
Comparison against the wishes: each wish, the wished value and this draft's value side by side; rows that differ from the wish or fall below the minimum kept for proposal quality are coloured, and re-measured each time you adjust.
Result labels are now "Meets the wishes" and "A wish given up".
Create from conditions: drafts found while working are shown early, and what differs between drafts is in bold. Export a proposal PDF for the customer (3D and key points, plus the floor plan).

Floor plans

Create from conditions: enter the lot size and what you want (rooms, floors, parking and so on) to get up to six draft plans. If none meets every wish, drafts made by giving up one wish are listed with what was given up (concession cards). A site survey, legal checks and finishing by a designer are still needed.
From drawings and images: rooms can now be created from images and scanned PDFs as well as plan drawings (as a draft; points to check are shown). Fixtures, the kitchen and stair direction are placed automatically.
After reading: points to check are shown one by one in a bar above the plan (Enter for the next). Name a room by clicking a suggested name, and add a missed room with "Add a room here" by clicking the empty space.
3D: switch between 2D and a rotatable 3D view (whole house, each floor, outside) and walk through the rooms. It is illustration-style reference CG, not photorealistic; export images and video.
Editing: free-form rooms, corner and wall editing, snapping and guides, multi-select, align, copy and paste (to other floors), layers, dimension lines (exterior dimensions drawn by default on new plans), area table, text with leader lines.
404 parts and 43 door and window types; choose how jō is counted (default 1 jō = 1.62 m²); seven looks plus sample company looks.
21 flyer templates (A4, B4, A3; 1–8 properties), export presets by destination, batch export, export to Jw_cad and DXF, to-scale printing, copy image to clipboard.
Start from 41 sample plans (including studio, 1K and two-family homes).

Drawing check and general

Cleaner screens; opening projects, importing drawings and selecting findings have been reworked.
When you have no projects of your own yet, Home shows three ways to start (check a drawing, make a plan from conditions, make a floor plan from an image), with sample drawings and images to try.
Unsaved changes in Floor plans are backed up automatically and can be restored at the next start after a crash.
The confirmation before sending anything to AI now shows what will be sent (images, PDF pages), each of which can be left out. Pressing Enter does not send.
Stronger protection against overwriting other people's changes in shared folders.
Floor plans made in 1.0.1 are saved in the new format by 1.0.2; the original file is kept as a backup (.v1.bak).
Project files that hold check-item results or confirmed values cannot be opened in 1.0.1 (so that saving in 1.0.1 cannot erase those records). If you share projects in a shared folder, everyone should update to 1.0.2.

v1.0.1

Released：2026-10-16

New "Floor plans": create colored floor plans for flyers and listing sites from drawings or plan drafts, adjust the look, and export in many formats.

New: Floor plans

Four ways to start: blank / trace an underlay (image, PDF, Jw_cad, DXF) / automatically from a plan drawing (Jw_cad, DXF, PDF) / from a floor plan draft.
Six looks (soft, simple, premium, monochrome, gray walls, hand-drawn); per-room colors and floor patterns; tatami layout for Japanese-style rooms.
Room names, jō counts, floor and total areas and the north arrow are filled in automatically; notes, company name and logo can be added.
61 parts (kitchen, bath, toilet, storage, stairs, furniture, cars, plants and more); add your company's parts and default colors.
Mirror left/right and up/down, copy for another lot, undo/redo.
Export to PNG, JPEG, BMP, GIF, TIFF, PDF, SVG and EPS; high resolution (4K/8K) and to-scale printing (1/50, 1/100, 1/200). If the scale doesn't fit the paper, you're told before export.
Before export, a side panel shows guideline checks for Japanese real-estate ads (jō count at 1.62 m² per jō, labeling rooms without windows); nothing is drawn on the plan.
Floor plans are saved in the project folder and can be shared; if saving fails, your changes are kept aside so nothing is lost.

v1.0.0

Released：2026-10-15

Rebuilt screens, framing-plan cross-checks, editable findings with a Jw_cad round trip, team work in a shared folder, and findings reports in Chinese and Vietnamese (updated on 2026-10-16 as the same 1.0.0).

Screens and editing findings

Product name shown as "Insight Home Design" (screens, help, report titles, installer).
Screens rebuilt: one main button per step, the rest under right-click and "More", so the flow can be followed without reading a manual.
Editing findings: dismiss a machine finding (stays dismissed on the next submission, reversible), edit title, body, severity, basis and position on the drawing, add your own findings.
Drawing editor and Jw_cad round trip: fix the drawing in the tool and save as JWW/DXF; "Open in Jw_cad" opens a working copy, watches for saves, reloads, and re-checks the fixed drawing as a new revision. The submitted original is never overwritten.
11 screen improvements: to-confirm and unchecked counts beside the floor plan status, "Import revised drawings" as the main button from the second round, the drawing zooms to a readable scale on the selected finding, a notice before printing untranslated findings, one dialog when drawings are dropped, the paper language per outside designer, open and overdue counts per outside designer on Home, due-date notices, fixes at 150% display scale, remaining Chinese/Vietnamese screen text, and a mark on editable fields.
For PCs whose window goes blank: Start menu entry "Insight Home Design (if the window is blank)" that draws without the GPU.
Display issues fixed (stale displays, wording mismatches, real folder paths shown on screen, and more). Error messages are now fixed texts (details in the log).

Drawing checks

Framing plans: reads sill, floor and roof framing plans (including pre-cut drawings) and matches their columns against the floor plans and foundation plan; mismatches are marked on both drawings.
Legal basis: setback from the boundary judged under Building Standards Act art. 54 (outer wall face); second-floor LDK escape via the staircase accepted. Items that depend on company standards are reported as "to confirm" and handled in the company settings.
Structural checks (re-checking the calculation sheets) made stricter to match the original text of the MLIT technical advice: quasi-bearing walls count up to half of the required wall length ("to confirm" unless a performance evaluation is noted), their treatment in the four-division method, and walls rated over 7 checked with both 7 and the actual rating. The four-division method without a note that the plan is rectangular, and N-values whose coefficients are not in the notice text, are "to confirm".
Performance: faster checks and lower memory, no law-library load at start-up, progress and "Cancel" for operations that take seconds. Results are unchanged.

Floor plan drafts

Surroundings (neighbours, roads, parks, waterways, railways) and district rules (height districts, district plans, building agreements) enter the evaluation; height districts are resolved from the site address; built-in garage type added; when the conditions cannot be met, a draft is still produced with a note of what was relaxed.
"Ready to use" is no longer shown while items to check by eye remain.

Team work and saving

Cases can live in a shared folder, with "who has it open" and read-only mode, and a merge on save that does not lose other people's changes.
Safer saving: changes that could not be saved stop closing or switching cases with "Save again / Close without saving / Cancel" (closing without saving keeps them next to the case, and they can be restored the next time it is opened). Nothing is saved where the marker that prevents simultaneous saving cannot be placed. Confirming a save conflict no longer blocks other people's saves.
Importing cases: a case exported by a newer version of the app is stopped with "Update the app". "Overwrite with the newer one" replaces the drawings only after the case is saved (otherwise everything stays as it was).
Trial records: per-finding "match / verdict / scope" marks and the time for the three steps are kept in the case and exported to Excel with detection rate, false-positive rate and time.

Languages

Screens, findings report, reply Excel and take-off sheets in Chinese and Vietnamese (finding texts, sheet headings and screens are translated; your checklist items, law names and room names stay in Japanese). Floor plan screens and the standard checklist items are also in Chinese and Vietnamese.

Update of 2026-10-16 (still version 1.0.0)

Floor plan drafts: the height limits of the site (road slope, north slope, height districts, absolute height) are worked out first, and the draft is laid out and sized so that the roof stays within them. When no position fits, the draft says so as "to confirm".
Floor plan draft checks now include whether the roof (eaves and verges) extends over the site boundary, including where the site boundary has a notch.
The setback for the road slope (Building Standards Act art. 56(2)) is now measured from whichever is closer to the road: the eaves or the tip of a second-floor balcony (floor plan drafts).
Road slope: on sites facing two or more roads, the area where a narrower road is treated as having the width of a wider road (Building Standards Act Enforcement Order art. 132(2)) is now judged as the article states, in both the drawing check and the floor plan drafts. In some places the limit is now less strict, and some roads no longer apply.
Check for law updates: "Check for law updates" on Home checks whether the articles in the national law database (e-Gov) have been amended. The articles in the law library are replaced only when you press "Update", and you can go back. The checks themselves do not change; findings that rest on an amended law are set to "to confirm" with a notice.
Law library: formulas with the explanation of their symbols (e.g. the sky factor formula in Enforcement Order art. 135-5), table titles and table notes have been added. They were missing before.
Law library: selecting an appended table with a branch number (e.g. Fire Service Act Enforcement Regulations, Appended Table 1-2-3) showed the text of Appended Table 1. Fixed. Selecting an article of a supplementary provision now also shows that provision's own text.
Usability fixes: rarely changed settings on Home are grouped under "More settings" and their text no longer gets cut off. The law library shows a larger list before a law is chosen, and the line above the articles is in plain words. Below the drawing panel of the drawing check, only the number of drawings is shown, plus the number of findings without a position when there are any (the breakdown appears on hover). The hint in the list search box, "More ▾" in the finding details, and the explanation on the trial records tab have also been improved.
New application icon (a house with a check mark on a drawing sheet).
