I am attempting to create an ASP.NET web application (C#, VS 2010) that will load a floor plan (.dwg file) and dynamically place a "marker " of some type on the floorplan to identify the location of some object not shown in the original drawing.
I do not want the user to need to have AutoCAD loaded on their computers for this to work. Is this possible?
Thanks in advance
You would need some way of modifying the file directly,
By using RealDWG
or Open DWG
Even you have RealDwg lisenced to run at the web server end, you still cannot present a *.DWG to a user with a ASP.NET application, that is, user cannot interact with a *.dwg file visually in a browser.
To make a pure web application, you need to publish a *.dwg into *.dwf file and embed "Autodesk Design Review" browser plug-in in a web page. However, I am not sure if the plug-in can post back to the web server with user input, so that the backend web server can use RealDwg to modify the corresponding *.dwg file according to the recieved user input.
Take a look at the following Component I use on our web site:
You may find what you need with it.
