    Posted: 03.Feb.2014 at 11:46
Hi all,

I am trying to recreate a .dwg version of a logo for a company called RWE. Their logo has a gradient in it, but it does not appear to be a linear transition from dark to light. I have tried using the gradient/hatch feature but it has not given the desired results. 

Does anyone have any recommendations how I can achieve an exact match for the gradient?

Here is the logo I am trying to recreate:

Just pick the two "extreme" colors - e.g. Color 152 and White and use the GR_LINEAR gradient with 90° angle.

GR_LINEAR gives a linear gradient, however I am looking for a non-linear one, i.e. a gradient that is logarithmic that starts off dark, gets suddenly lighter and then from the middle point starts getting lighter slower and slower.

Their logos are .BMP files, which is one of the file types supported in AutoCAD's IMAGEATTACH command, so you can just insert one that way into an AutoCAD drawing.

Would you be able to elaborate a bit on the process, I am not familiar with that command.

Oh actually I misunderstood you, I have already attached the image, as I am tracing it. I cannot use the original image for the gradient because I need it to be compatible with other pieces of software, therefore it all needs to recreated purely using cad and not the original image.

How about an approach like this?  You can vary the proportions between the two areas, or use more than two areas if that gets you the look you want.  Just make sure the "end" color of one gradient is the same as the "start" color of the next one.

Cheers Kent, I did approach it like that and it worked great. I was hoping there would be easier/quicker way, but this way although a bit time consuming did work well. 

Cheers for your response.

Brilliant solution Mr. Cooper!  I'll have to make note of it.
