Process to Import PDF Files as AutoCAD Geometry in AutoCAD 2017





Many AutoCAD users use PDF files in their everyday workflows, exporting them to share design content for review and importing them into AutoCAD files to add valuable existing content to designs without recreation of content. These additional capabilities, however, have always come with some restrictions.

Displaying content and controlling it is possible with Object Snap and Layer Display settings (at time of creation of PDF and if it is setup properly), changing geometry within AutoCAD software was not possible earlier. AutoCAD 2017 finally has come up with a solution and made this much-needed change.


How to Import PDF into a Drawing as Geometry?


Newly improved Import command now supports importing PDF geometry as AutoCAD objects. Anyone can access this with newly added application option, Import > PDF, or from Insert Ribbon tab inside Insert panel.
  • After Import File dialog box is displayed, the file can be seen which has been recently imported to list of supported file formats.
  • One can also type in PDFIMPORT command and use File option to display Import File dialog box from the command line to bring a newly converted file into the drawing file.

After specifying a particular file for import, import dialog box will be displayed, which will allow users to apply settings and options on how to import the file as geometry. One can have a variety of settings that a user can choose from which are as follows:
  • Selecting a page to import as geometry from a multi-sheet PFD file.
  • Setting Scale, Rotation, and Insertion point of the imported geometry.
  • Type of data that can be imported is
  • Vector geometry, Solid fills, TrueType Text, and Raster images.
  • Control layer assignments for imported geometry
  • Set a variety of import post-processing choices on how to convert and handling incoming geometry.


Different Options for Exporting PDFs


Most options for importing files are understandable, but there are a few which may require some additional explanation like:

Raster images can be extracted as .png files and get attached to the drawing file. Generally, image files are stored in path location in Files tab of Options dialog box. Paths can be absolute or relative to the location of the file being imported.
  • PDF file format does not distinguish SHX text. Also, data from drawings with SHX fonts, when plotted can be stored as geometry. When imported back into AutoCAD software, it is recognized and treated as geometry and not as simple text. Drawings with Windows TrueType Fonts are stored as Text and imported back into AutoCAD as text.
  • The “Converting solids fills to hatches” option will join 2D solids with corresponding edges to create hatch objects. This option will increase overall processing time.
  • If “Apply line weight properties” option is on, it would be applied. If not default setting would be applied.

Converting Existing PDF Underlay

In case if you have an existing PDF underlay in the drawing file and need to convert all or some of geometry into AutoCAD objects, one can use PDFIMPORT command to import file.
After above step, select how you would like to select your objects by a Window, Polygon, or all in a file.

Next step would be to do different things with the existing PDF Underlay which was selected: Keep, Detach, or Unload. Selecting Settings option from the first prompt will display Import Setting dialog box.

An alternative easy way for converting geometry is by using the built-in functionality inside AutoCAD object properties. This can be done by selecting an edge of PDF on the screen (nothing else should be selected). This will display Underlay contextual ribbon tab. Now select Import as Objects tool on Import panel and follow steps as mentioned above.

This tool can have some difficulties if the file has a poor quality. The best recommendation would be to turn off certain layers inside PDF (for example dimensions) and rebuild file in smaller pieces. Every AutoCAD update makes workflow a bit simpler for users. For gaining knowledge about latest updates, it is always advisable to learn this tool from a recognized CAD training Institute which offers advanced and certificate CAD courses and can enhance the skills of individuals. Also, it will help students in developing their portfolio which can showcase their projects.

The advantages and disadvantages of the animation technology in education and training

Introduction People are always looking for new ways to educate their children. If they are having fun, they learn better. Computer animation can be used to make very exciting and fun animations into which education and training can easily be incorporated. It is much more interesting to learn math for example when the letters are nice and colorful and flying around your TV screen instead of solving problems on plain black and white paper. Other subjects such as science, English, foreign language, music, and art can also be thought of using computer animation. Instructors can also use computer animation to demonstrate things visually exactly how they want to since they have control of every aspect of the animation. It can be used to show how things come together and work together. In science, for example, the computer animation might be used to show how our solar system works, and in math, a computer animation might show a student how one can algebraically manipulate the specifi

         DIFFERENCES BETWEEN AUTODESK REVIT AND 3DS MAX Hi, all, being into the counseling profession, I have come across a question that majority of engineers and beginners who wanna make a career in CAD (Computer Aided Design) put up. That is what’s the difference between Autodesk Revit and 3Ds Max. And which one is better for us. What career options are available after doing Revit or 3Ds Max software? So here are the answers. I’m giving you a comparative advantage in Revit and 3Ds Max. Hope the difference will clear much of your doubts. Revit3Ds MaxSuitability Autodesk Revit is best for architecture designing 3Ds Max is highly recommended for rendering. Type Revit Architecture is a Building Information Modeler (BIM). Whereas 3Ds Max is a 3D Modeling tool. Features Revit Architecture interface is designed to simplify your workflow. Revit can generate excellent results for concept modeling, construction documentation, Bills of quantities. Revit
