1.5.0
- 3D section result: stratum interfaces built from the borehole
contacts in the MDB (stratum tops, soil/rock interface, groundwater
level; at least 3 holes), interpolated and extrapolated to the site
boundary and clipped to it, kept below ground and in stratigraphic
order; each surface can be switched on/off in the web page and they
are exported to a GeoPackage PolygonZ layer (with a PointZ layer of
the borehole contacts and a ready-made 2D/3D style).
- 3D 剖面成果圖：新增地層界面——由 MDB 各鑽孔的地層界點（各地層頂面、土岩界面、地下水位面；至少 3
孔）內插並外推至計畫（基地）範圍後裁切，限地表以下並維持地層上下順序；網頁中各面可個別開關，並輸出成 GeoPackage PolygonZ
3D 面圖層（另含鑽孔界點 PointZ 圖層及預設 2D／3D 樣式）。
- Confirmed interfaces: the surfaces can also be built from the
stratum boundary lines of the (geologist-edited) 地形剖面 layer of each
section project (soil/rock interface, rock contacts by their lower
unit, groundwater), alone or together with the unconfirmed MDB ones;
the mesh is refined along the control data so the surfaces follow the
section lines, and each surface reports how well it fits its controls.
- 確認版地層界面：可改由（技師修改後）各剖面專案「地形剖面」圖層中的地層界線（土岩界面、依下層區分的岩層界線、地下水位面）建立 3D
面，可單獨或與 MDB（未確認）界面並列；網格沿控制資料加密，面貼合剖面界線，並列出各面與控制點的吻合度。
- Dialogs fit the screen (tabs scroll on small screens); groundwater
surfaces are always drawn in aqua.
- 設定視窗依螢幕大小調整（小螢幕時分頁可捲動）；3D 地下水位面固定為水藍色。
1.4.0
- New "3D section preview" button: builds a 3D model from the DEM,
drapes the layers visible in the map canvas over the terrain and
stands each generated section drawing on its section line
(self-contained web page, three.js bundled, opens in the browser;
requires a DEM layer).
- 新增「3D 剖面預覽」按鈕：以 DEM 建立 3D 地形，地表貼上地圖畫面開啟的圖層，並將產出的剖面圖依剖面線位置立於 3D
剖面上（單一網頁、內含 three.js，以瀏覽器開啟；需有 DEM 圖層）。
- 3D preview: plan and section legends; "cut terrain along section"
works without facing a section first (uses the section nearest the
view centre and follows the camera side).
- 3D 預覽：新增平面與剖面圖例；「沿剖面切開地形」不需先正視剖面即可使用（切開最靠近畫面中心的剖面，並隨觀看方向切換切除側）。
- 3D preview screenshot includes the title, a north arrow and the plan
and section legends.
- 3D 預覽「下載截圖」加入標題、指北針及平面、剖面圖例。
- New "3D section result" tool: combines a plan-map project with the
section projects as edited by the geologist into the same 3D web page
(sections matched to section lines by stored name or file name).
- 新增「3D 剖面成果圖」工具：選擇平面圖專案，結合地質技師修改後的各剖面立面圖專案，產生相同功能的 3D
網頁（依專案記錄的剖面名稱或檔名對應剖面線）。
1.3.2
- Call-out leader arrows now end inside the stratum they point to
(last segment runs along the unit centre line).
- Call-out 引線箭頭改落在該地層上下兩條界線之間（引線末段沿地層中線水平進入）。
1.3.1
- Stratum names: thin units get a smaller font; units too thin for 8
pt are labelled with a call-out instead of being omitted.
- 版面地層名稱：較薄地層自動縮小字體，太薄時改以引線（call-out）標註，不再省略。
1.3.0
- Fix: with "use MDB measured dip", rock contacts, apparent-dip lines,
symbols and the layout note all use the same apparent dip (mean of MDB
bedding/cleavage/schistosity dips).
- Fix: stratum names are placed between the unit's upper and lower
boundary lines.
- Layout note reads "dip direction (azimuth)/dip"; warnings show the
project number when an MDB holds several projects.
- 修正：勾選實測傾角時，岩層界線、地層視傾角線、符號與版面註記統一使用同一視傾角（MDB 實測傾角平均）。
- 修正：版面地層名稱改標示在上下兩條地層界線之間。
- 版面註記改為「傾向方位角/傾角」；MDB 含多個計畫時，警告訊息標示計畫編號。
1.2.0
- Fix: rock contacts are always extended at the apparent dip (direct
correlation between adjacent boreholes is now optional).
- Fix: joints, shear planes, fissures, tension cracks and veins, and
all discontinuity symbols, are drawn at their apparent dip.
- Layout note with section azimuth, attitudes and apparent dip;
apparent-dip and fault lines are labelled with their angle.
- Generated projects open zoomed to the terrain-profile layer.
- 修正：岩層界線預設一律依視傾角延伸（相鄰孔直接對比改為選項）。
- 修正：節理、剪力面、裂隙、張裂隙、岩脈的短線及所有不連續面符號，改依視傾角（實測傾角＋代表傾向）繪製。
- 版面新增剖面方位、代表位態與視傾角註記；地層視傾角線、斷層線標示視傾角。
- 產出的專案開啟時縮放至地形剖面圖層範圍。
1.1.2
- New check: warns when water_tables elevation differs from collar
elevation minus water depth.
- 新增檢查：water_tables 的水位高程與「井口高程 − 水位深度」不一致時提出警告。
1.1.1
- Fix: rock contacts stop at any borehole whose log they would cross
without showing the contact.
- New checks: duplicate borehole coordinates, overlapping columns in a
section, gaps in core-photo coverage.
- The borehole layer is saved into GroProfile.gpkg after a run, so it
survives reopening the project.
- 修正：岩層界線延伸時，碰到任何有鑽到該深度但沒有此界面的鑽孔即終止（原本只檢查相鄰鑽孔）。
- 新增檢查：MDB 中座標相同的鑽孔、剖面上柱狀圖重疊（重疊鑽孔間不做地層對比）、岩心照片缺漏深度。
- 鑽孔位置圖層於產製後存入 GroProfile.gpkg，重新開啟專案不會遺失。
1.1.0
- Representative rock and fault attitude inputs; apparent dip computed
from the section azimuth decides which way strata dip.
- Rock-to-rock contacts drawn and extended by apparent dip until a
fault, the soil/rock interface, the ground surface, the section frame
or a neighbouring borehole.
- Fault lines, apparent-dip form lines (bedding, cleavage, ...) and
every discontinuity class with data added to the terrain-profile
layer; legend lists only types present.
- Bedding/cleavage symbols rotated by apparent dip; fixed legend size
estimation that caused overlaps.
- 新增岩層／斷層代表位態輸入，依剖面方位計算視傾角並判定傾斜方向。
- 地形剖面新增岩層間界線（鑽孔間對比連線，未對比者依視傾角延伸至斷層、土岩界面、地表、剖面邊界或鄰孔）。
- 新增斷層線、地層視傾角線（層理／劈理等），以及節理、剪力面、裂隙、岩脈等各類不連續面；圖例只列出有資料的類別。
- 層理／劈理符號依視傾角方向旋轉；地形剖面圖層新增終止原因等欄位。
- 修正圖例尺寸估算偏小，避免圖例與剖面標示重疊。
1.0.2
- 程式碼品質：修正 Flake8 E741（變數命名）。
1.0.1
- 修正 Qt6 / QGIS 4 相容性（列舉值改用 scoped 寫法）；通過 Bandit 安全掃描（移除 subprocess
後備讀取器、不再靜默略過例外）。
1.0.0
- 初版：Geo2020 MDB 讀取、鑽孔位置圖層、DEM/等高線地形剖面、批次產製 QGZ + GroProfile.gpkg、131
個工程地質圖元、岩心照片檢視、程式說明。
