PreDCR User Manual

What the manual covers

The PreDCR User Manual explains how to create, modify and verify architectural drawings that meet AutoDCR software requirements. PreDCR works within the AutoCAD environment and provides additional menus, toolbars and commands for creating layers, assigning names and checking drawing entities.

The guidance is relevant to users, draughtsmen and architects preparing plans for automated processing of Development Control Regulations. It is technical drawing guidance rather than a description of property ownership or title.

Supported proposals

The PreDCR User Manual supports these proposal types:

• Amalgamation, by drawing the initial plots on the Plot layer and the resulting plot as a closed polyline on the Amalgamation layer.
• Subdivision, by drawing the initial plots on the Plot layer and each subdivided plot on the Subdivision layer.
• Building development, by drawing the plot on the Plot layer and the proposed work inside it with all proposed building details.
• Separate drawing files are required for land division cases and building development cases.

Main drawing requirements

The PreDCR User Manual sets the following preparation requirements:

• Plot layout, detailed plans for every floor and building sections for all floors must be in one AutoCAD drawing file at 1:1 metre scale.
• Building items such as the proposed plot, proposed work and proposed parking must generally be closed polylines.
• The permitted building item entities are LWPOLYLINE, TEXT and MTEXT.
• Centre lines of main roads, internal roads, railway lines, drains, water lines and electric lines may be open.
• Building sub-items must sit completely inside their outer closed polygon. No edge or vertex may extend outside its containing entity.
• Each building sub-item should have a specific or unique name on the same layer and inside its polyline. AutoDCR may generate a name if none is found.
• Room and floor names should follow the stated naming conventions without abbreviations so that the software can identify them.
• Floor polylines must contain all architectural details.
• Mirrored proposed works require separate building plans for each proposed work.
• Other details intended for final printing, including column footing and compound wall details, must be placed within an OtherDetail polyline.

Layer and checking tools

PreDCR provides layers and short commands for features including amenities, architectural projections, balconies, buildings, carpet areas, chowks, compound walls, doors, electric lines, existing structures and floors. Its tools can highlight unclosed entities, missing names and other failed drawing checks before AutoDCR processing.
