Imported images, scaling and moving

ken

OK, I am working on a tunnel under a shipping channel that was built in 1930. So all the construction drawings are scanned images. No chance in converting to ACAD files.

I use a program to select sections of the drawing that I am interested in and import the images into to Sketchup as a PNG image.

I get my images from the set of PDF drawings that were sent to me, old Internet photos of the site, from navigation charts, and PDF reports from years past.

My problem is that I need to overlay each image at the correct scaling and positioning, such that I can make different views showing the various information on top of the model I am creating. So this requires that each image be scaled and moved to accurately overlay on the images below and have the correct alignment with the model.

Not all the scanned drawing are scaled correctly in the X and Y directions, why not, not sure, bad scanning or a bad drawing, wrinkled maybe. So this requires that each section cuts needs to be scaled correctly in the X and Y directions, which means there needs to be some separate X and Y scaling, and some re-alignment of the total image in the X and Y directions, until the two, three or four or more images, are at the correct scaling and positioning.

I have tried Jim’s JF Moveit 2.1, and TIG’s Texture tool. Neither tool gives me the desired results. The native Sketchup scaling and Move Tools do not work well with images.

So, am I missing a plugin that will scale images separately, in the X and Y directions, and move the image in the X and Y directions according to my inputs?

As an example of my input. Scale in the Y direction by 1.5, Scale in the X direction 1.2. Move in the Y direction 12”, move in the X direction 3’.

If there is no plugin that I am missing, guess, I will do the best I can, going to be a long night.

Have you try ThruPaint by Fredo6?

You don't need a plugin to do this. import the images as textures and apply them to faces inside components or groups. Then you can open the components one at a time and resize the texture as needed. Unlink the X and Y dimensions of the material so you can size them in each direction as needed.

Thanks for the help. I got it done. Guess I need to do more with textures.

Again thanks

Ken, while I was driving to work this morning I remembered something I should have added. Sometimes when I need to trace an image in SketchUp and I know the X and Y dimensions aren't correct, I scale the image for one direction and don't worry about the other right away. Then I get busy tracing and at least get the basics drawn in. Then I scale the other direction to correct it.

Glad you got it finished anyway.

Thanks. I do that also, but this was the first time I have multiple images that I wanted to overlay. Normally I have one image that I use and you method works. However, I wanted to turn on the X-Ray view on so they could see all the images stacked.

It seems with the slowing down with work in the Gulf of Mexico, they are chasing more inland work. So this is why I am getting more and more scanned files, from projects that were constructed in the late 30's to the early 60's.

Anyway thanks.
