[esp-r] Re: Dxf import

[Jon Hand]

A recent question about importing DXF CAD data into a model...

The import facility assumes that you are importing into an
existing ESP-r model which does not have any zones defined.

To do this start up the project manger (prj) and ask to create
a new model. Supply it with the initial site information that
it asks for.  Click on 'save' or 'save as' and make a note of
the file name that has been created. This is the ESP-r configuration
file that the import funcition requires.

When using the DXF import function remember to have saved
the DXF file as version 12 (the last version that there was a
freely available description of the contents).  When giving
the name of the DXF file include the full (explicit) path as
well.

There have been past discussions about the specific contents
of DXF files that are recognised (3DFACE and 3DPOLY) and the 
rules (each zone is on a separately named layer).  An easy
way to find out the entities is to export a current ESP-r model
as a DXF file and look at the contents.  

Some users have noted that if the import process fails the
messages genereated are somewhat opaque. We have recently
started to investigate such issues but work is not yet complete.

Remember that an alternative to direct import is (for the X11
version of ESP-r) to turn the CAD data into a bitmap and then
use the click-on-bitmap function in prj to create new zones.
Sometimes this is faster and allows much more control of
which CAD entities you choose to include in your model.

Subject: [esp-r]  Dxf import
 
Hi every one,

I tried hard to import a dxf file into ESP-r but failed. The program asks
for a .cfg file. I tried to enter a new name for the .cfg file but the
result was an empty model. I tried to pick an existing .cfg file but I got
error messages related to missing parameters in the .cfg file.
Can someone tell me the procedure to do it. I found only support materials
about the criteria of the dxf file and its layer arrangement.

Thanks
