The best feature of this product was its ability to integrate seamlessly into our existing software applications (such as Autodesk Revit). We can now use it in conjunction with other programs such as SketchUp or even Microsoft Excel! It has been difficult learning how everything works - many features are not intuitively obvious at first glance but require some research before you fully understand them all. I would recommend getting help from someone who already uses these tools/programs if possible because they will be able to guide you through any issues quicker than trying out new things yourself without support. This tool made managing projects much easier by allowing us access to view multiple versions easily; also very helpful when submitting change orders due dates were approaching quickly.
