Issue

Some IFC files cannot be read:

ISO10303-21: Skipping instance #743204: Instance  is not syntactically valid.

Workaround

The relevant lines can be changed in a text editor, e.g. from 
#743204=IFCCARTESIANPOINT((0.,0.,520)); to #743204=IFCCARTESIANPOINT((0.,0.,520.));

The IFC files are in fact syntactically valid. Other software and validations do not throw errors on that issue.

In FME 2025.0 and newer, we have a new IFC Reader (short name: IFC_API) which is more flexible with syntax. 

For missing decimal places, the new reader should be able to handle this.

Try it out!
