Areas, not a complete model
Fourteen ground-floor and two basement polygons are saved. There are no rent spaces, vendors or assignments in the database.
01 · Extracted from CTM-Spaces
The existing market map
The architect’s site plan is the base. CTM-Spaces places image-coordinate polygons over the right-hand side of the market.

Scale needs confirmation
The code uses three conflicting calibration values. The geometry aligns; the stored square-metre figures are not yet trustworthy.
Functions on the architect’s plan
From traders’ market, warehouse and truck stop to cold rooms, loading fingers, roads and parking.
02 · New CAD package
Seven drawings, viewed safely
A browser cannot draw DWG natively. These cards use the preview embedded in each DWG; the source files stay outside the public web directory.
The local SVG test is not publication quality
The AutoCAD 2018 files can be read, but text, hatches, images and some curves disappear. The next reliable step is an architect-exported vector PDF or cleaned SVG for each paperspace layout.
03 · Implementation structure
Keep the drawing and the data separate
CAD is the reference geometry. Operating data belongs in stable, named records displayed as layers over that geometry.
-
01
Import layer
DWG stays private. A reviewed PDF/SVG and small WebP preview are generated once and visually checked against the architect’s source.
-
02
Geometry layer
Important spaces become clean polygons with stable IDs, such as HALL-A-017, instead of timestamp names.
-
03
Operating layer
Tenant, category, tonnes/m², rand/m², power and GridView data reference the geometry ID—never an image pixel position as a business rule.
