Laser scanning requires some different technology to create models. Most of the time, we like to have native objects in Revit, AutoCAD, etc. To get that, you need to either model right inside the native software, or use something like ClearEdge's EdgeWise software to match objects to the clouds. Many modeling companies are experts with this process and it is likely to be cheaper to hire it done for one or two projects. There's a tremendous amount of education and cost into extration on large scale.
Take a look at the AutoCAD 2016 point cloud tools. Autodesk is now including tools to work with point clouds. Anyway you cut it, drafting/modeling on point clouds is a slower process than modeling proposed design concepts often completed for construction documents.
