edbardet Posted February 27, 2020 Share #1 Posted February 27, 2020 I'm sorry, but I can't find a post about this subject. It concerns setting up the measurements in blender. The author showed how it was done by, I believe sizing the image and setting up the right measurement parameters. If any one recalls the post I would appreciate the link. Or if anyone has a method, please let me know. Thanx, Ed Quote Link to comment Share on other sites More sharing options...
SardonicMeow Posted February 27, 2020 Share #2 Posted February 27, 2020 Are you talking about scaling and positioning plans into the Blender 3D environment? You might be thinking about my post below, where I show my method for doing that. (Note that I was using Blender 2.79, and some elements of the user interface are different in Blender 2.8.) If you are still unclear on the procedure, I'd be happy to go through it step by step with you here, perhaps using your plan files.

edbardet Posted February 27, 2020 Author Share #3 Posted February 27, 2020 Peter, I was using your post but the '50 pixels per foot' has thrown me. How did you come up with that? I have the image in, centered and set at 0,0 for the forward point. Thanx, I'd like a bit of help. Ed Quote Link to comment Share on other sites More sharing options...
malachy Posted February 28, 2020 Share #4 Posted February 28, 2020 The '50 pixels per feet' probably is just a measurement taken from the original plan in a program like Photoshop or GIMP Quote Link to comment Share on other sites More sharing options...

Here is an image from the plans which includes the scale. It goes from 0 to 110 feet. I brought into in a graphics program (I use GIMP) and noted that the 0 mark is at X value 342 and the 100 mark is at X value 5342. 5342 - 342 = 5000 pixels from 0 to 100 feet. Therefore 5000 pixels / 100 feet = 50 pixels/foot. (Your result is likely not to be a nice whole number as in my example.)

edbardet Posted February 28, 2020 Author Share #6 Posted February 28, 2020 Am I being dense? Wouldn't it be easier to put a cube of a known dimension and scale the drawing so that a similar distance is the same. IE I have 2' station lines and I scaled the drawing so that they were at the same distance as a 2' cube. Shouldn't this work? Quote Link to comment Share on other sites More sharing options...
herask Posted February 28, 2020 Share #7 Posted February 28, 2020 Ed, that's the way I usually do it. I put a placeholder of required dimensions in the scene and then scale the plans in the background to fit the object. it's certainly not 100% precise but it is good enough. the thing is, when building ships you usually have exact dimensions stated for individual objects (Lees, Steel, NMM plans...), so use them when modeling, background plans are there more for reference than for CAD-precise-like modeling...

edbardet Posted February 28, 2020 Author Share #8 Posted February 28, 2020 Thanks Denis, I think this is the easiest way. Reminds me of a discussion from years ago regarding development of a raked transom. Some ways took pages and i just took a couple of sentences.

malachy Posted February 29, 2020 Share #9 Posted February 29, 2020 A reference object in the modelling app works, too, of course. But I take measurements from the plan(s) anyway, if only to check if there are distortions and if the horizontal pixel/feet ratio is the same as the vertical one. And if you already have a pixel/feet ratio, why not use it in the app? Quote Link to comment Share on other sites More sharing options...
