[Equest-users] Fw: Help: System requirement for high rise projects.

[Bruce Easterbrook]

   I would expect that computation time would slow considerably with 
this scenario.  Not only do you have 2 high rises to run but you also 
have the shading interaction with the 2 buildings.  This is a good 
approach.  From a work efficiency point of view and easier trouble 
shooting it would make sense to start your model with one building.  
Create a base model up to the point you have major deviations in the 2 
buildings.  Make 3 copies, and go forward with each building and have 
one copy as backup.  I normally spend a lot of time at the edge of the 
DD wizard and the DD edit fixing problems and making sure the model is 
running correctly before going into the DD edit.  This will allow you to 
troubleshoot each building separately and then once the buildings are in 
the same model all that has been added is the interaction of the 2 
buildings as shades on each other.
    I think a big mistake new users are making is not progressing along 
a logical building and troubleshooting path when creating their models.  
If you deal with each stage discretely it limits the number of errors to 
troubleshoot and places to look for them.  It is a more efficient use of 
your modelling time in the long run.  It also breaks your time 
investment into stages as well.  There is nothing worse than getting 15 
hours into a model, have a critical error and have your file disappear 
into cyberspace.  Almost as bad, is to have 2000 error messages and 
trying to figure out where to start.  There may only be 10 real errors 
but a basic error is like a chain reaction through the whole run and 
will generate a multitude of associated errors. If you are lucky and it 
runs that long.
   Sorry for the drop on the list, seems my email send configuration was 
improperly adjusted.

>>     This is Rajesh, I am using equest from 6mnths. I need know system requirement, for equest when have to model high rise building. Actually, when I model fifty storey building, & run the BDL, atlast it comes out to insufficient memory, & it gives errors. I use floor multiplier to reduce load on PC. My PC configuration is intel  dual core processor, with 4 GB RAM. If I have to upgrade my pc, then what would be its configuration. If I have to buy a server, then is it possible that equest will run on it. If I have to model a 100 storey building, kindly give solution.  I would  greatful for the solution.
