I'm evaluating OG Pro as I have a heavy reliance on Visio but would love to move to a native diagramming solution and I like OG. I understand a few of the issues with shading and transparency and I can work around not using those in my diagrams to ensure compatibility. What I can't come to terms with is how my converted file (from .graffle or .vsd) exports it to a .vdx format that is at least 200-400% larger in file size. I've tried this with a variety of diagrams ranging from the simplistic to multi-layer / multi-canvas files, the results are always the same; the files become huge. Is this a common / known / expected outcome, or, is there something amiss here? Anyone had any experience with this? Thanks.
