If there are dimension lines and arrows in an iges file, does OCC ignore all that when importing/reading the file? I have an iges file with some dimension lines but they don't show up when I read the file in. According to iges.PDF section 2.2.1 Translatable Entities, it make no mention of dimensions so I'm assuming that they are just chucked out the window when importing. Please tell me I'm wrong, and there is a way to read all the dimension lines in along with the model. Thanks.
