CAD (computer-aided design) drawings are digital files that house 3D & 2D models of physical objects. CAD files can include information such as geometric data, manufacturing data, material properties, and other data. CAD files are ‘to-scale’, meaning designers are able to create drawings in real-world dimensions.
CAD and Revit systems continue to be popular because of their capabilities to assist with:
- Creating Detailed Models
- Facilitating Collaboration
- Energy-Efficient Design Planning
- Cost Estimation
In today’s environment, almost every design project involves a CAD file.
What CAD software does Armstrong use?
Armstrong uses Solidworks because we appreciate the efficiency the software brings to the process of designing and building packaged systems, working with digital components and subcomponents.
From the standpoint of design features, we appreciate the excellent visualization tools (for interference checking) and image creation tools in SolidWorks.
Can I ask my architect for CAD files?
An architect may be willing to furnish design files. Be advised however that, depending on the agreement you have reached with your architect, they may be under no obligation to provide files.
What are the most common CAD file types?
The most widely used software package for CAD drawings is AutoCAD, which saves files in .dwg format. Other popular file types for CAD design include: .dwf, .dwg, .dxf, .acis, .bmp, .3ds, .ipt, .igs, .stp
Do architects use CAD or Revit?
Both file types are widely used by design firms and the differences in capabilities make the two types of systems complementary. CAD Systems are often used as a drawing tool, as they present buildings based on their geometry and measurements. Revit Systems represent components based on the function they serve within a building.
What's the difference between native CAD files and neutral CAD files?
Native CAD files are drawings created in only one specific type of software. Although there may be ‘export’ and ‘import’ capabilities in other software packages, native CAD files are often 100% compatible with only the original software package.
Examples include: AutoCAD, CATIA, Creo, Inventor, NX, SolidWorks
Neutral CAD file drawings are independent of software programs and can be used and exchanged between many different design systems.
Examples include: IGES, STEP, STL, QIF
