    • AutoCAD includes the .dwg format and provide the support as well. It provides a way to use the files that are active.
    • It provides a way to estimate the total number of active .dwg files that can be made in collaboration with other files.
    • It provides languages that can be used and the localization part of the software can be modified to meet the requirements.

    Question 5. What Is The Function Of Vertical Integration?

    • AutoCAD uses the vertical integration program to enhance the architectural designing of 3D objects.
    • The 3D objects can include walls and other things that are associated with the data having intelligence and association with the simple objects like lines and circles.
    • The data is programmed such that it represents only the architectural products and the extracted files.
    • The information for the data and the actions on the like modifies and creates the relationship of an object.
    • It consists of the tools that allow the estimation and other objects related representation in the 2D drawings.
    • The elevations and sections used as a 3D architectural model specifies the standard calculations used in creating applications.

    Question 6. What Is The Use Of Variants In AutoCAD?

    • AutoCAD uses lots of variants including the releases that provide capabilities to build an application.
    • The 3D capability that is being provided by the AutoCAD gives fewer rises to the releases of the applications.
    • Variants are used to increase the variations present in the application or the package used in particular program.
    • AutoCAD provides variants that help in creation, visualization and rendering of the 3D models that provide the 3D printing as well.

    • Setting up the dimension style also requires the use of documents and creation of the styles while using the blank document.
    • The document is saved by using the document as a Drawing template and then new references gets created by the template document.
    • Templates define the system variables that can be consistent across all the platforms and provides the drawings like layer styles, units and blocks.
    • It can be copied by copying the styles on single case basis and the drawings can be done by seeing the current drawing.
    • Using of the design center makes it easy for the AutoCAD tools to allow the browsing and copying of the styles and other drawings activities.

    Question 18. What Are The Steps Involved In Copying A Closed Drawing?

    • Use the Tree View to navigate to the closed drawing file location.
    • Expand the drawing to access its components (blocks, layers, dimension styles, etc.).
    • Drag and drop or copy/paste the desired elements into your current drawing.

    Question 19. What Is The Way To Hide The Specific Layers When Plotting?

    • The prevent layers using the plotters for plotting provides the layer manager that allow easy options to customize.
    • Options include: Turning off the layers, Freezing the layers, Turning off the layers for plotting.
    • Layers used in the plotting remain visible on the screen and doesn't provide the output to the printer.
    • It uses the viewport concept that allows the different layers to be frozen on the view port.
