AutoCAD Xref Cleanup
One of our readers presented an AutoCAD/Xref/Management/Performance
problem.
Essentially, a landscape architect receives dwg
files from surveyors which are used as Xref base
plans. These files are large with lots of
surplus entities which impacts on the
performance of the assembled final AutoCAD
project. Cleaning the base files manually
(erase, purge, etc) is time consuming, and if
the source files are re-issued, the process would
then need
to be repeated.
Two important initial cleanups - Purge All and
Delete All Layouts - could be automated by
using the following macros:
[Purge All] ^C^C-purge;all;*;n
[Delete All Layouts] ^C^C(foreach i (layoutlist)(command
"-LAYOUT" "DELETE" i))
These routines, plus others, to delete
particular items (shapes, layers, etc) could be
built into a button [CleanupXYZ] for each
consultant.
AutoCAD's strength over the past 25 years has
been the ability to automate repetitive tasks
through some simple programming and AutoCAD 2009
extends that ability with the Action Recorder.

TIP
for new installations of AutoCAD
When a new installation of AutoCAD is started
for the first time, and there has been/is a
previous version on the computer, AutoCAD will
ask if you wish to migrate the settings,
customisation etc from the old one to the new.
The default is yes. Our recommendation is DO NOT
say yes, instead configure the new release from
scratch. Although having the best of intentions,
AutoCAD will carry over some settings which
reference the previous version installation.
These paths may not remain valid for the new
installation, and removing the previous version
will only exacerbate the problem. Mostly this
tool works reasonably well, however we have seen
a fair share of problems to support our
recommendation.
Revit RPC Content
RPC (Rich Photorealistic Content) is now
included in Revit 2009. RPC technology uses high
quality images combined with simple geometry to
create the illusion of 3D. By changing the image
as the camera moves through the scene, RPC
objects reproduce the appearance of a
3-Dimensional object without relying on complex
polygonal geometry. RPC Trees, Shrubs and
Grasses are now included in Revit 2009.
Landscaping in Revit couldn't be easier -
take advantage of over 100 RPC Trees, Shrubs,
and Grasses.

AutoCAD/AutoCAD Architecture 2008/2009
If you have noticed significant performance
issues in AutoCAD when performing
Open/Copy/Paste/Insert actions with drawings
that contain Xrefs, the problem most likely lies
with Annotation Scaling Objects.
This may help.
