Due to the complexity of these applications, user training is also recommended. However, for CAD applications to work better, high-speed CPUs, a modern graphics card, and large amounts of RAM are recommended. Typically, CAD applications don’t require any special hardware to run and are available on all major platforms. Examples of popular CAD software are AutoCAD, SolidWorks, CATIA, NX, Inventor, and Solid Edge. The use of CAD software improves productivity, quality, documentation, and manufacturing of a product.ĬAD software is extensively used in Automotive, Aerospace, Marine, Construction, Industrial Equipment, Healthcare, Consumer Goods, Retail, High-tech, and Energy Industries. CAD software is also used for digital prototyping and digital content creation. CAD software is used for the digital creation, analysis, and optimization of a product design. It means all the contour lines have elevation or height value.įigure 7.CAD Files – Types, Formats, Extensions, and ViewersĬAD stands for Computer-Aided Design. In figure 8 we can see the contour lines are stacked respectively based on it's elevation. Figure 8 is the view of CAD data in x,z axis. Figure 7 shows the contour CAD data with x,y axis on the screen (z axis towards us). To try it, open the output DXF using a CAD software. In CRS option, the coordinate system of exported output CAD can be changed if it's required.Ħ.
Choose AutoCAD DXF for Format and specify the output path. Right click the 3D vector contour layer, select Export then Save Feature As.The save as window will show up like figure 6. Now, it's ready to export the contour data to CAD dxf Format.
Before conversion the Geometry was Line(MultiLineString).ĥ. Look at the Geometry type, it should change to Line(LineString25D). The properties window will appear as in figure 5. Open the layer properties by right click the layer and choose Properties. The converted 3D vector will be added to QGIS layer.
