Takeoff R6 PDF Import

By Ray Antaya • March 1st, 2013

First things first in order to import a PDF on Carlson Takeoff you’ll have to install Ghostscript http://sourceforge.net/projects/ghostscript/.  “Ghostscript is a suite of software based on an interpreter for Adobe Systems’ PostScript and Portable Document Format (PDF) page description languages. Its main purposes are the rasterization or rendering of such page description language files, for the display or printing of document pages, and the conversion between PostScript and PDF files.”-Wikipedia

Once Ghostscript is installed on Carlson Takeoff you will be able to import a PDF. There are two types of PDF’s a Raster Format and a Vector Format. For this take off project we’ll be using a Raster Format.

Raster Format (bitmap) is a dot matrix data structure representing a generally rectangular grid of pixels. Raster graphics cannot scale up to an arbitrary resolution without loss of apparent quality. Here are file formats that represent bitmap images: TIFF, JPG, JPG2000, and PNG. The PDF can be a raster image if it is not created from ACAD such as a scanned copy of the plan page.

Vector Format is a PDF is created from a vector based application such as: ACAD the resulting PDF contains vectors describing all the lines, arcs, and shapes in the drawing. The output can be scaled with no loss of resolution. “No jagged edges”.

 Here are the steps to import a PDF as a raster image:  go to the File drop down > Import/Export > Import PDF.

Then locate the desired PDF for the takeoff and open. Next a box will appear to prompt you to Insert Linework, Edit Layer Table, Insert as Image, and Save to Image File.

Pick Insert as Image when you choose this command Carlson Takeoff is creating a separate raster image of the PDF which is called a .TIFF file. Next a screen will prompt you to save the TIFF file.

 I save it in the same folder that the Takeoff file is in.  You are then prompted to Save image as:  color or monochrome. I save it as Color.

You will then be prompted, in the command line, to Pick point to insert raster. You can pick a location point on screen or enter a coordinate such as: 1000, 1000.  After you choose the location for the image you are then asked to Specify scale I press enter on the default <1>.  We will scale the image once it’s on screen. Then you are asked to Specify rotation angle again I press enter on the default<0.0>. Now your image should be on screen. If you don’t see it I recommend going to the View dropdown> Zoom > Extents.
