Esteemed colleagues in Autocad
I need knowledge on Tif files, how to import them into drawings, etc...Any and all basic information about that and raster editing would help greatly.
Thank you

I need knowledge on Tif files, how to import them into drawings,

Use the ._ImageAttach command.



...Any and all basic information about that and raster editing would help greatly.


You can edit bitonal images inside of AutoCAD with Raster Design. Otherwise, you will need some 3rd party application to edit the images outside of AutoCAD.

Hi Bill.
There is a lot of info in acad help.
They must be uncompressed and not 16-bit colour depth.
IMAGEATTACH command to attach then.
Scale and Rotate to manipulate them.
TIFOUT to create a file from a drawing.
Create a raster device to plot to a file.
RasterDesign or similar to play with the pixels.
?

Thanks for the help. I had a feeling it was a file to attach using the imageattach function. Scaling is important if you can provide and basic info, or tips on scaling tif files.
This is info I need for a company I may apply to. I have attached images in the past, and worked a little bit with roster images, but never as a regular function within my job, so I just needed basic info on just as you provided, image attach, and scale and rotate basically, so I can go into an interview and say I have some knowledge of working with Tif files. I know it's not complete, but I believe they're just looking for someone to insert those files into an autocad drawing, and properly scale them.

Once you have attached the image, identify a known length, draw a line and two crossing lines ( @ 90 degrees) to mark the known length then offset one by the known distance.
Use the Scale\Relative command\option to scale the image known length to the true size.

+------------------------+---------------------------+
1=origin
..........................2=end of line in image

.........................................................3=true distance
