Architectural Desktop 2007 Service Pack 1 released

ADT 2007 SP1 was made available for some days ago and I recommend to download the readme and see if it make sense for you to install it. It includes the AutoCAD 2007 SP1 as well so there is a lot of reasons why you should install it.

...improving upon a number of features within the product, some of which include, Construction Lines, Doors,Inserting DXF Files, Multi-View Blocks, Project Management, Properties Palette, Reference Keynote Legend, Roof Slabs, Spaces, Stairs, Style Manager, Tool Palettes, Windows while also addressing early customer feedback.

Performance is also improved in some areas. Project-based callouts will no longer make plot preview that slow. File open time has also been somewhat improved. This is true if FIELDEVAL is set to update when plotting or opening. The use of Project Standards will no longer have a significant effect on file open time.

Notice also the hotfixes:

Hotfix - Plotting to Raster Files Performance Improvement

Hotfix - Regenerating Drawings Containing Text
