I'm trying to figure out how to "fix" a point to an image inserted by the "Sketch Image" tool, in order to scale it to the desired size. Let me explain: I want to model an M2HB, an old cal.50 machine gun from the second war, I have built up my library of images to be able to take my dimensions and have several views in detail. The thing is that for my rib shots I wanted to take a profile picture of the weapon and use it to take my ratings: I put two points at each end of the desired rib, smart rating and I find it. But you still have to be able to put the image at the right size!
In the past, when I had modeled a grenade launcher, I had put two dots with the right space (usually the total length of the weapon that serves as a reference dimension) and I had then played with the dimensions of the image so that my two dots fell more or less where I wanted. Of course it's quite risky as a technique, especially on much larger parts (here almost 2m for the M2 against a little more than 40cm for the LG...) and very annoying to set up...
Do you know a way to size my image so that the two ends of the displayed weapon are at exactly the right distance in order to facilitate my future dimensioning please?
After creating a sketch on this sketch, draw a straight line of the desired size
Close your sketch
You make a sketch again and you insert your sketch image that you can put in semi transparency to visualize the beginning and end of the image to the right of this line
and play with the proportion of your sketch image by timing it as best as possible
Personal: - I crop my image so that the edges of the image coincide with the object; - I insert my image into a sketch (create sketch / tools / sketch tools / sketch image), at that point I can size my image to the right size directly.
@gt22 gives you the right solution because in the sketch image you have a window that allows you to give the exact size to your image. The other solution is to make your model and scale it once finished with "" Insert ==> Function ==> scale ""
Be careful to set your image to the origin otherwise you'll be emm..... constantly to center your object in the middle of your screen. That's why it's in your interest to make a sketch that you transform into a block and it's this block that you call back to start building your model.
Same solution as colleagues. In any case, with a sketch image as a support, you shouldn't expect to have great precision. It is once the main lines have been drawn that the dimensions must be refined .
