Season, Architect • 2018

I need a list of disadvantages of ArchiCAD from user experience.

Praveen, Interior Designer

Hello Season. Below are the disadvantages of ArchiCAD: custom articles require GDL scripting, numerous old workarounds are never completely fathomed, a few expansions are never legitimately refreshed and less-utilized API. 1 More Answer

Cari, Architect

Hey Alan, editting an IFC element doesn't imply meyhem... you can move them around to your hearts content, and if they are composed of a typical archicad object, you can edit to the heart is content. Where you run into trouble is if the object is a particular manufacturers product and you change it, well, it'snot really their product anymore... 8 More Answers

How can I build a railway br

Zerihun • 2015

A bit tricky but I need to build a railway bridge in Autodesk Revit. Has anyone done this before or know of an easy way or pre-made Revit family?

Michael, Architect

The question is impossible to answer without knowing more about the design of the bridge. There is almost no such thing as a pre-made bridge (except maybe in the military.) Every bridge is unique. Revit can model almost anything you want from it. I have been using Revit since 2003 and have never found anything it can't do if you put your mind... 14 More Answers

I have recently started to involve some my clients with BIMx. And, they love it. At this stage I am using it in the concept stages of the design. When I get the confidence, I'll eventually use it for the final drawings too.

Standing Seam roofs drive me nuts. I have read a lot of forums. Nowhere can I find accurate information on that. Any help will be appreciated.

I guess it depends on how specific you want it to look. I use a material called Roofing - Metal Standing Seam that I set to use an ootb Relief Pattern called Standing.Seam.png to control the Render Appearance, and a simple Model Surface Pattern called Standing Seam - 16" (etc.) to control it's graphics for Plans and Elevations, and it works g...

I'm a little bit worried about my current file size, I'm at 350mb and not even finished yet! What is an acceptable file size to have?

There are many variables to consider with respect to file size - complexity of the design, size of the building, number of levels, source of the content loaded, end-user methodologies, and certainly L.O.D. To answer your question, any file size is acceptable as long as it still performs well. In my 7+ years with Revit, I've never had a projec... 6 More Answers

mikey • 2012

Currently working on a project with multiple people and just curious if there is a great way to communicate the changes made by each person?

Werner P

I would suggest creating a template that maybe everyone fills out, e.g. stating all the changes, but not sure if that would get to complicated especially because that's quite dependant upon the number of changes and the number of people involved. 1 More Answer

Moving from a trial version

Marco Antonio, Architect • 2012

I'm currently using an ArchiCAD trial version, if I decide to buy the 'full' version will I be able to convert/transfer my files?

Rachel, Architect

I haven't done this but I have heard that when you buy the actual ArchiCAD the trial version automatically switches to 'full' version and the files you created in the trial version will be converted to your new 'full' ArchiCAD files. But this only works if you are using the same computer for both the trial and full version. Hope that helps! 3 More Answers
