model generated from external XML file?

Not applicable
Hello all,

Is there a way to building an AC model based on info attained from an external XML file. If so, what programming/scripting language does ArchiCAD employ to achieve such need?

ArchiCAD does have XML capabilities, but I am not too familiar with them. Why do you ask? Do you have a particular need? This is an odd way to post a wish list item.

Hello Matthew,

thanks for your response.
I ask because I am currently experimenting with form generating algorithms, using adobe flash technology. The resultant form, can be described/stored in XML format. I would like to (somehow) feed that XML file to ArchiCAD to produce architectural representation.

Such process could be achieved with SketchUp, I am now wondering if I can eliminate SketchUp, and do everything in ArchiCAD.

Regarding the oddness of the post.
Sorry, I was confused. I learned that this was a wish list section only after I have posted.

But, in response, this can be done either via GDL - in which case the model would be a single monolithic GDL object when finished - or via the API in which case individual building elements can be created.

Personally, I would think it could make more sense to write a script that converts the XML into an IFC file?

thanks Karl for addressing my miss post.

I have looked up IFC building model at:

I would like to look into this a bit more.
Do you have any suggestion as how get started with writing IFC files?

thanks for your suggestion

Sorry, no. Haven't looked at the IFC spec.

Much of the work done by ONUMA & Associates utilizes a similar technology.

To be honest, that's as much as I know...
