chelsea1307 Posted October 6, 2009 Posted October 6, 2009 Is there a way to insert a pdf into a dwg so that only only the object on the pdf shows and not the white background? Quote

ScribbleJ Posted October 6, 2009 Posted October 6, 2009 Do you actually mean insert a PDF as if you were inserting an image? Quote
chelsea1307 Posted October 6, 2009 Author Posted October 6, 2009 yea, sorry about that, took a pdf saved it as a png and did an image insert Quote
chelsea1307 Posted October 6, 2009 Author Posted October 6, 2009 no i dont have photoshop, Remark i looked at the link you posted and it left me a little confused. I am tracing over a pdf to show some existing piping, with the white background it makes it hard to see some of our standard colors, right now I have it set up so i can change the layer colors back and forth to be able to see them with the image over them and then the colors we plot with. Was trying to avoid having to change all the colors Quote
happyunited Posted October 8, 2009 Posted October 8, 2009 This has happened to me sometimes and it is rather useful. Unfortunately I don’t actually know how I do it as sometimes it just inserts without the white background and sometimes it hasn’t the background. It must be something to do with the image. Quote
ScribbleJ Posted October 8, 2009 Posted October 8, 2009 The only way to make the white areas of the image not show is by having Raster Design then you can set the the color of the pixel selected (in this case white) to be transparent. Quote
gilsoto13 Posted October 13, 2009 Posted October 13, 2009 Is there a way to insert a pdf into a dwg so that only only the object on the pdf shows and not the white background? I had the same problem once... I had some "original" pdf drawings... and When I converted them into .jpg to use them inside autocad, the backgroung was transparent automatically... then when I used our scanner to make .jpg or .pdf the background was always white, and I could convert them to tiffs and then use the transparency button to make the white color get transparent.. but I think autocad didn´t recognize those tiffs as valid image files... so I had to stay with my problem... But... I recently downloaded and checked Autodesk Raster design... also downloaded a tutorial somewhere to transform a raster image into lines or plines.. and it wasn´t handy at all.. but the fact is that it uses a the cal format.. that does exactly this.. any image format you have... you can convert it to cal and this is a format with transparency and solid pixels only, it looks like vectors with some speckles depending on original hardcopy scanned document. This is what you can use to mix scanned documents with new vectorized information if you don´t want to vectorize the whole scanned drawing. If you use Autodesk Raster design there is a menu called "Image" and it has an option to export to cal Als, if you can get autocad 2010.. there is a new tool for attaching pdfs with this cal format. Otherwise... try to find a program to export from pdf or jpg to cal... I tried to find it but I could find it in acrobat 8 nor in adobe illustrator 11... maybe you can find a small image converter to get your jpg to cal easily. Quote
chelsea1307 Posted October 30, 2009 Author Posted October 30, 2009 took a dwg i plotted and scanned it to pdf and did a saveas to png and it had a transparent background when i inserted it in autocad, did it with another pdf and it had a white background im at a loss to the difference other then knowing the source of the first pdf was scanning on an oce scanner Quote
