I love that you can create your own models by combining other programs together with CAD drawings. The program also works well in combination with AutoCAD drawing software. There are many functions that need more development for better integration with different types of drawing software. Currently it has limited use when compared to some of its competitors. Also there needs to be some way to add notes to the files or documents as they are created because currently everything is saved as plain text which makes searching difficult if needed later. This product integrates very nicely into our work flow allowing us to access information quickly without having to manually search through multiple applications.
