Proposed DDR Changes

Travis Wagner

Problems with DWG/DXF files via DDR

• Issues we have heard:– Current method of block creation causes

AutoCAD to crash when opening large areas (Utility & Planimetrics)

– Slow draw times– Clean up work on user end

• Any others we haven’t heard about?

Proposed Resolution

• Use different template that shows points as an “X” where they are still visible by changing PDMode = 3 and PDSize = 5

• For attribute data, export method as “extended entity data”

Extended Entity Data (EED)

• Benefits– Smaller file size (2 quarter sections: Planimetrics 1.54

MB vs 616 KB)– Does not create points as blocks– Still get attribute data

• Load .lsp file “eedcnvrt.lsp”• Gives you “eedconvert” command to create object

data from eed data• Creates a new table for the converted eed data • Ability to select exactly what features to extract from the

eed data and exactly what fields

– Cleaner files (no fme block to purge out or explode)

Thoughts

• Does the current method work for your organization?

• Would the proposed change benefit your organization?

• Discussion

Other DDR Topics

• How are you currently accessing DDR?– Via cities– Via public DDR interface
