Whatever your role in construction projects, reliable documentation will be crucial to the success of your endeavor. This documentation can take many forms, including building permits, contracts, purchase requisitions, work schedules, and many different types of drawings. These drawings can exist in many different forms, from hastily drawn sketches and hand-drawn blueprints to full-blown three-dimensional computer-aided design (CAD) models.
So, whether you’re working on a solo project or you’re a member of a project team, you already understand that you’ll be compiling, handling, and storing technical drawings. What you may not know, however, is that there is often a need to convert these drawings from one form to another. It is sometimes necessary to convert hand drawings into digital images or to convert records from one file format to another.
This process is called CAD conversion (or CAD migration). Different CAD software packages create and save files in different formats. If one of your suppliers requires CAD information in one proprietary format, but your CAD file is in a different proprietary format, it may not be possible for the supplier to read your file. A conversion services firm can, however, quickly and accurately convert your file into whatever format your supplier needs.
There is a similar type of data conversion, however, called Revit conversion. And Cad Crowd has experts with years of experience handling Revit conversion services for residential, commercial, and industrial projects of all sizes.
Revit is a Building Information Modeling (BIM) software. It is a product of Autodesk, Inc., an American company with headquarters in California that has been producing software for about 35 years. You may know about the company through one of their other products, AutoCAD, which coincidentally has about a 35% share of the CAD software market.
BIM stands for Building Information Modeling. It is a comprehensive approach to managing all of the data generated during a construction project, including 3D CAD models, budget and cost analyses, scheduling plans, and other information about the project (collectively referred to as metadata). The word Building in Building Information Modeling doesn’t mean that this software is limited in use to the construction of actual buildings. As the methodology has evolved, BIM is now used for development ventures of all types, including infrastructure construction like bridges, roads, utilities, and water projects.
Building Information Modeling can be thought of as a process for handling both the documentation and the design aspects of construction projects. It is a set of best practices that utilizes all the available information so that the timeline of the project can be executed effectively throughout the entire project lifecycle.
In addition to its usage during new construction, BIM is also being employed in the areas of historic preservation, restoration planning, redevelopment of historical sites, and expansion projects.
As mentioned earlier, each type of CAD software saves data in its own proprietary format. Enterprises choose to work with proprietary files because each software package can store certain types of information that other systems can’t. (CAD drawings contain drawings, of course, but other data like dimensions, part names and numbers, vendor information, etc.)
When CAD drawings are saved using the software’s proprietary format, that specialized data is saved as part of the file. Now, it just so happens that all CAD software can save files to generic (aka neutral) formats that are easily shared between different software platforms. However, when saved to a neutral format, drawings will be successfully saved but the specialized data will often be lost. So, companies are often locked into using different proprietary file formats, and this means their files will need to be converted before they can be read by users of other systems.
This CAD-to-CAD conversion process can be complicated and time-consuming. It differs from Revit conversion in the amount and complexity of additional data that must be dealt with. Think of the Revit conversion process as CAD-to-BIM conversion. Revit conversion service companies have to ensure that 1) the drawing information is accurately converted, 2) the ancillary information (dimensions, part names, etc. mentioned in the preceding paragraph) is also switched over, and 3) all the additional project metadata is correctly migrated as well.
People from all walks of life and businesses of all sizes utilize Revit conversion services, including:

Revit conversions can be broken down into three classifications:
This is actually one of the more common reasons for working with an AutoCAD drawing services firm. At the beginning of a project, sometimes only paper blueprints are available. By having these paper blueprints converted into Revit BIM files, not only can changes to the design be made more efficiently, but project information can be shared more easily among project team members.
Even large projects often begin with nothing more than back-of-an-envelope sketches. A BIM conversion services firm can convert these 2D images into BIM files, which will add visual depth and interest to your designs. The CAD drawings and other information in these files can be easily retrieved and printed.
Speaking of storage, paper drawings are often difficult to store. They are subject to weathering and deterioration and are easily misplaced or lost. Drawings stored in a BIM file are readily reproduced and multiple copies can be easily printed. Also, by converting your paper drawings into digital ones, you’ll be creating permanent records of your designs.
There are a number of other benefits to using an Autodesk conversion service company to convert your project documents to Revit BIM files:

An exciting new method of converting existing project information is the direct conversion of laser scans of a job site into a BIM model, a process known in the industry as Scan to BIM.
Best practices surrounding CAD drawings for a construction project will include mention of as-built drawings, which as the name implies, are digital models of the project at various stages of completion. As-built drawings will invariably differ from original design drawings due to change orders, alterations to the plans made in the field to accommodate unforeseen obstacles, and, we hate to say, sometimes just plain bad workmanship.
By far the best method of creating as-built drawings is to use laser scanners (the “scan” in “Scan to BIM”) to image the construction project. This process is sometimes referred to by either of two acronyms – LIDAR (Light Detection and Ranging) or LADAR (Laser Detection And Ranging). These scanners send out pulses of laser light into the surrounding environment. Sensors record when the light is reflected off any object and returned to the system. Circuitry within the scanner accurately measures the transit times of the laser pulses. The result is that the distance to every point on the job site or in a building is recorded with incredible accuracy.
The entire set of data thus stored by the scanner is known as a point cloud model. A point cloud model file is often huge – tens or hundreds of gigabytes in size. To make that much data more manageable, a process called point cloud modeling converts this data into a 3D model of the project complete with accompanying metadata (which is, of course, the “BIM” part of “Scan to BIM”).
As you can imagine, there are a number of benefits to contracting with a Revit scan-to-BIM conversion services freelancer:
Direct conversion of as-built construction information into a Revit BIM model should be an essential component of your project lifecycle, not only when responsibility for the finished product is transferred from the construction team to the property owners, but also for the duration of its occupancy.
