Continuing the discussion from IFC import to SketchUp:
I think IFC import and export deserves it’s own Help Center page(s) listing file types, specification versions, limitations, drawbacks, etc.
This category is for SketchUp Help Center issues. THIS topic thread is a discussion and request for a SketchUp Help Center article on SketchUp’s native IFC import and export features / implementation / strengths / limitations / workarounds, etc.
If anyone has direct firsthand knowledge and experience and would like to promote ideas, tips and tricks for a SketchUp Help Center article, please post your suggestions in THIS topic thread.
Otherwise, click here to expand advice on where to post questions, etc., ...
If you wish to discuss or ask questions about using or writing 3rd party import and/or export APIs, please post your question in the Developers > Ruby API category, or the Developers > SketchUp SDK category (whichever applies best.)
If you have questions concerning the end user manual interaction or performance with published 3rd party import or export extensions, please post your question(s) to the Extensions category (with the name of the extension as a prefix to the topic title in brackets.)
"[Fast OBJ Exporter] Entity id not exported from SU2018"
If you are concerned with the (built-in) native SketchUp Pro IFC importer or exporter …
a. … and are questions about current general use, features and performance, then please post to the main discussion SketchUp Pro category.
b. … are about bugs, lack of features, improper files or data after import or export, then please post your questions or reports to the Technical Problems > SketchUp sub-category.
No IFC file types listed on page:
No instructions nor benefits or limitations given in the Help Center.
(At least no right column section link.)
I did find a general paragraph on IFC import / export on the Classifying Objects page:
You can export the objects into other formats or programs. When you export SketchUp objects, they can contain all kinds of higher-order representations of things. For example, if your project workflows use BIM, you can export objects classified using the IFC 2x3 schema from SketchUp into the open BIM data exchange standard, IFC. (IFC stands for Industry Foundation Classes, an open data model standard for building information.) Rendering applications can use these attributes, such as material type and light sources, to simulate a scene. SketchUp’s APIs expose all the additional data that developers need to make rich importers and exporters from just about any information modeling format.
