Dear Mr. Dennis,
First I would like to apologize about my English, my native language is
Portuguese here in Brazil.
Yes, it is possible to be done and we are working to do it but, we have a
long way before get good results.
(1) We have a central site on internet that many constructions companies
has an account (http://www.sistrut.com.br/sadp in Portuguese) . Each
Client (construction company) can open many Projects inside their accunt.
Each Client can register many project companies or individual consultant
in their area (Users). This project company or consultant can be registered
in another Client too. The Cliente will give the hability for each User to
access the system (download and / or Upload) only in the projects that they
are working. Each User has a 'level' (Structural, Architect, Hidraulic,
etc) and could be registered to access your own level and others levels too
(structural can access Architceture and Hidraulic - example).
When a User (project companie) send a new file to a project area of a
Client, the system will send an eMail to all users registered in this
project with message about a new file is available with the comments about
Ok, first steep is running ! we have a central (dataWarehouse) to storage
files and document it.
(2) This second steep is were I am working now and the most difficult to be
solve. I would like to introduce on this system, a service like a 'chat
drawing' were each one that are connect in this service will be a drawing.
This drawings have to be a normalization.
Scale, layer names, one fixed point by coord x,y, etc.
This drawing have to be save on DWF format (Drawing Web Format)
Why this steep is the 'bad' steep ?
Because we create the system not for one company but for many companies
that would like to utilize it. The problem here in Brazil is that each
construction company has a different padronization of drawing, most of then
(small companies) do not have padronization. The project companies do not
understand that a 'drawing file' is not a file to be 'plotted' , there is a
lot of information inside of the drawing. This file is not a drawing, it
is a project. When I start this work, 3 years ago, I wrote a
document with the title 'CAD Draw x Project' (look at
http://www.sistrut.com.br/Grupos/grup_E.html) . The main propouse of this
document were explain that the CAD files should be done to be read and not
only to be 'plotted' . We have to define a normalization of layers, scale,
etc that specific softwares like 'Structural Softwares' can read this files
and get information (not visual) there. We have it runnig in our
(3) The last steep, we are developing a CGI program to run on this service
that will create a 'chat drawing room'. Each one that enter on this room
will point a drawing that is storage in the Client area (1) and everione
has the hability to this project. If you update your drawing in a storage
area, the system automaticaly reload and redraw the selected layers of all
drawings on the room.
How is the great advantage of the system ?
This syetam have FTP and HTTP codes. You will send (UpLoad) files to an
FTP temporary area and, register the file sent on the system by HTTP
(site), internet address. When you register it, working in a GCI
program, the system has the hability to send eMails and update registers
about Project, users and Client.
I hope give you an ideia about our procedure.
