Hello DataCAD Pro's,

I have a scanned image in a PDF of a hand drawn floor plan and would like to reproduce it in DataCAD. I was thinking about importing it somehow into DataCAD and then drawing over the top of it...maybe by saving it as a JPEG and then inserting it as a bitmap into DataCAD. However, my question is what is the best way to go about this?

Also, I would like to be able to scale it so that my drawing units are correct.

Thanks in advance for your help,

CADwk :roll:

Just how you said it, save/export to an image file (150-300 dpi, depending on the size of the area of the image you want to use, a large image at a large resolution might have a hard time printing on some print drivers). Import it as a bitmap. If you are using the Pen Table to print, I suggest setting in the pen table under Bitmaps and Fills to 'In Order'. Then make sure your image is drawn in a color that is a lower number than the pen color you wish to draw your CAD linework with. Nice thing about using In order, it allows you to use multiple images with multiple layers of CAD drawing if needed. If your not using the Pen Table for ordering, then using layer order and display order and the Move to Front/Back commands will be used to get things in the proper order.

I would suggest inserting it into a blank file and save that new AEC file. Then xref THAT into the file that you will be creating your drafting over. This will allow you to scale the xref file to a known dimension/feature, AND it will allow you to rotate the image however you'd like - otherwise the JPG won't rotate if you need to tweak it a few degrees or 180 degrees.

Funny thing is I have done this before and had no problems (although normally I use PDF files inserted into DataCAD, not sure if that would make a difference). I import a bitmap scan of (in this case a site plan) and then draw over the image in a color, a boundary that represents the area of work. I do commercial TI's.
I've tried the move front to back and vice versa but my boundary remains hidden behind the bitmap. The red L shape is under Building B (I made a duplicate just for explanation purposes).
