1Overview
Drawing Extents are project attributes expressed as SouthWest and NorthEast coordinates. infrADAC ACAD and infrADAC BCAD reconcile stored metadata, XData and the physical rectangle. infrADAC DCAD accepts typed coordinates, native south-east/north-west Plan picks or the extents of models displayed in the last active Plan view.
Starting a project, changing its spatial boundary, resolving an out-of-bounds audit or replacing a missing extent definition.
2Before you begin
- Work in the correct coordinate system and drawing units.
- Know the intended minimum and maximum project coordinates.
- Zoom to the project area so a newly drawn rectangle can be checked.
3Extent sources and validation
host storage differs, but audit consumes the same SouthWest/NorthEast project values.
| Feature or choice | Current behaviour |
|---|---|
| SouthWest | Stores the minimum project X and Y coordinate.It defines the lower-left audit/export boundary. |
| NorthEast | Stores the maximum project X and Y coordinate.It defines the upper-right boundary. |
| infrADAC ACAD and infrADAC BCAD reconciliation | Compares saved NOD data, XData and physical extents rectangle coordinates and prompts when they disagree.Stale or duplicated boundaries are not silently trusted. |
| infrADAC DCAD form | Loads native project values and supports typed X,Y, Plan corner picks or displayed-model extents from the last active Plan view.12d does not depend on a DWG rectangle object. |
4Set the project boundary
Define the two project corners and save the boundary used by audit and export.
Run the command
The host checks its current extent state.
- Run
ADACDrawingExtents; infrADAC DCAD can also useADACDrawingConfig. - infrADAC ACAD and infrADAC BCAD: allow the command to inspect saved values, XData and rectangle objects.
- infrADAC DCAD: review the current values, then choose typed coordinates, Plan corner picks or Plan-view model extents.
Define the corners
SouthWest must be left of and below NorthEast.
- infrADAC ACAD and infrADAC BCAD: pick or enter SouthWest and NorthEast X,Y.
- infrADAC DCAD corner mode: pick the south-east point followed by the north-west point in a Plan view; the form normalises these to SouthWest/NorthEast values.
- infrADAC DCAD view mode: make the intended Plan view active and calculate the combined extents of its displayed models.
- Correct any reversed or invalid axis values before saving.
Save the extents
Store the selected coordinates as the project boundary.
- infrADAC ACAD and infrADAC BCAD: confirm the rectangle shown in the drawing represents the intended boundary.
- infrADAC DCAD: confirm the SouthWest and NorthEast values in the form.
- Select Save or complete the command prompt.
5Product differences
Can draw, regenerate or reconcile the project extents rectangle in the AutoCAD database.
Uses the equivalent BricsCAD entities and drawing metadata.
Run ADACDrawingConfig or its ADACDrawingExtents alias. Enter coordinates, pick the south-east and north-west corners in a Plan view or calculate extents from models displayed in the last active Plan view.
6Troubleshooting
Multiple extents rectangles are detected
Choose redraw/regenerate as prompted, then keep a single authoritative infrADAC extent object and rerun the command.
Audit says coordinates are out of bounds
Check both the project attributes and the actual design coordinate system. Do not enlarge extents merely to hide wrongly located geometry.
infrADAC DCAD rejects a corner or view
Use a Plan view, accept both native corner picks and confirm the resulting axes are valid. For automatic extents, ensure the last active Plan view displays at least one model with calculable extents.
