Overlaying a Car On the Template

What do you have to do in order to overlay a car on the template? I am not as computer savvy as I need to be. Or do you request a particular car to be done?

I'm not computer savvy either.
I photo-enlarged the 'Template' in a copy machine up to a scale where the max camber point height is 82mm,on 11"X17" paper.
I'll take the subject car photograph to the same copy machine and scale it up also to 82mm in height.
I have a light table on which I can register the two images together,or just carefully place them,and then use Post-Its or drafting masking tape to hold.
By pushing a stainless steel push-pin through the 'Template' and into the photo below I end up with a series of holes which I can connect with a French-curve drafting instrument to draw out the contour.
After this,additional photo-enlargements can be made if you like for greater resolution when measuring angles or dimensions.
It's low tech but will get you in the hunt.

You could download this: GIMP - for Windows and read the tutorials or do like I did and ask a twelve year old to do it for you.

I couldn't find a 1990 Accord picture, but I did find a 1993 Seville :



I am not sure about the center of max roof camber (the first vertical line on the front window), so I hope others chime in. If it is correct, it seems like you could have a small spoiler on the rear to help the aero.

Thanks for the responses. This may sound odd, but I wanted to see how a 1985 Buick Riviera would look on the template.

Here's a fourth gen Accord. When searching for blueprints it helps to use the chassis code (CB in this case), which can be found on Wikipedia. http://carblueprints.info/blueprints...d_cb3_1989.png

In Photoshop, put the template on a layer above the car and in the Layers tab in the drop down menu change "normal" to "multiply". This will essentially remove all white tints from the image, making it see-through.



If you print this out large it would be very easy to scale it up to full size with some drafting tools, since it includes dimensions

Oh, and that Riv blueprint may not exist online so here is one from a photo. It's okay... I wouldn't be surprised if there were no separation on the roof.

Here be my version. I use Micrisoft Word, I use the Insert Shapes & Insert Picture functions, then save it as a PDF (I have Acrobat), then save that as a JPG. It is a little complicated but it took about 7 minutes to make this & edit it. I load it into Tinypic.com then link to it here because the ecomodder web page is a pain to load images onto, but it links to stuff great.

The template needs to go further back on the Seville; when some of the roof pokes through the template, that's not allowed.

I think that's not true. For my wagon the roof pokes through the template because it *violates* the ideal shape :



But I could easily have the center of max camber wrong. When I slide it back it looks great :
