I have question, I have hardcopy paper, maybe 1:1 or 1:2 but that angle,width that anything no dimensions. I not understand how to draw correct dimension that. is it possible scan that paper, save to TIFF, and use CAD to open that TIFF file (background). and I try draw that line again. from that Image background. any idea please!

You have answered your own question save to jpg maybe rescale image to a known value and trace over correcting as you go.

thanks, but my cad program not found that Import>Image that function. I am used that 3rd cad program. is it "Autodesk" special function? also if "Autodesk", which version is it support or need LT or 3D?

Are you saying there is no IMAGEATTACH command in the version of AutoCAD that you are using?

[yaim229]

thanks, imageattach is my need command, i'm sorry I not clear my question. also, if future I want to delete that image. simple type "erase" completed. am i correct?

[ReMark]

Yes, the image can be erased just like any other object.

BTW, how to known that import image is 1:1 size? and if re-draw, that lines, normal I need what Technology?

There is no guarantee the image will come in at 1:1 scale. You would have to scale it based upon some reference.

 

Once the image is scaled then draw over the top of it using normal lines, arc, polylines, etc.

 

What is the image of that you are attaching?

[yaim229]

thanks, in this moment, no any image need redraw that lines. but If known how to perfect redraw that lines) that technology, is not bad. cad program very powerful, but, basic level, I know how to draw that lines,arc,maybe enough.

In other words you are not doing this at the moment and your question was merely for informational purposes. I see. OK.
