I have received IFC files for other members of the design team. When i import the IFC file into AecoSIM i get different (and less acceptable) results than if i open it in AecoSIM. Why is this? Secondly is there any way around this? If i import i can get the family and parts and therefore cut sections and plans etc (apart from the missing elements that disappear when i import!) however if i open it i do not get any of this and therefore cant use the model in my drawings.
Opening an IFC file in AECOsim Building Designer is comparable to opening the IFC file in an IFC viewer. The graphic output you see is usually very good but AECOsim Building Designer only creates solids.
Importing the IFC file in AECOsim Building Designer creates AECOsim Building Designer elements as far as possible using families and parts. If AECOsim Building Designer creates a reference during the import you can merge the reference into the active file. Then you have e.g. walls, etc.in the active fille that can be edited.
The IFC 2x3 CV2.0 data exchange format - CV means Coordination View - is only designed for a coordination view not for an 1:1 data exchange. The creation of AECOsim Building Designer elements is done as a best effort but does not ensure that all elements are displayed correctly.
- Did you check the options in File menu > Import IFC > Settings tab?
- As an alternative you can reference the ifc-file and then merge it into the active file.
- You can check if the IFC export in the software that created the ifc-file offers different options. That might improve the ifc-file and also the IFC import result in AECOsim Building Designer.

"The creation of AECOsim Building Designer elements is done as a best effort but does not ensure that all elements are displayed correctly."
wow, that's a pretty fundemental to say that the program doesnt do!! so how am i supposed to know if the elements are displayed correctly???? I've got a 13 storey building with many thousands of structural elements it is impossible to go through and manually check each and every one to ensure that they have been displayed correctly.
- Yes I've checked the options in the import IFC tab.
- I cannot reference the IFC file in as i require the model to be imported on a floor by floor basis due to it's size and for ease of use when modelling. I also need the family and parts applying so that i can get plan and section cuts taken from the model.
- The IFC is exported absolutely fine, it's independently checked via Solibri by a 3rd party before we are issued with the information.
- We are data mapping everything correctly and as per the IFC import thread.
Below is just one example of a random 'block' that appears and stretches up through 13 storeys of building!!!
The top view is taken from Solibri and the bottom view is the imported IFC from AecoSIM. This is just one of a number of similar errors we are seeing with these files and it's making it very hard for us to trust the information we are modelling against, we've had;
- slabs disapprearing
- random placement of structural blocks
- flanges from steelwork disappearing
- holes in slabs not showing
