As part of my job, I have to recreate models of old ammunition (1900-1950) for identification documentation that will be useful to our employees in the field.
I have little experience in 3D apart from what I have learned on the job on my own during the last few years.
Very interesting job. In any case I wanted to make a small remark, which is that the graduation is not proportional, from 1 to 3 they are larger than the rest. Have to make 1 line in projected extrusion then make a circular repetition with constant pitch. Too bad the doc is in German^^ I love the old plans (by hand) If I have some time, I will do some tests to submit to you.
Here is my quick little test, and indeed the wrap / wrap function I can't take advantage of it. It was necessary to cunning by creating another volume with the graduation, which is beveled with a removal of circular material and finally a subtraction of volume between the graduations on the ring.
All that remains is to make a nice table with a rule of 3 to convert the linear position of the graduations in relation to the angles (whose minutes must also be converted) Edit: the length of the sketch line2 is equal to the perimeter of the bottom part of the ring. or 182.84mm For the intermediate graduation I didn't bother him, I distributed it homogeneously between 2 large graduations with the lines and the equal stress. You also have to adjust the text heights and the font if necessary. (it all depends on whether there is a reproduction behind it or just for the illustration).
If most engravings are to be done on cylindrical or conical faces, the use of the Wind... function can give a satisfactory result. It seems not to be able to work on other more complex surfaces (sphere, torus, etc.).
The most difficult part is to position the characters or graduations to be engraved correctly in the 2D sketch, so that they are correctly placed after winding. A fairly simple procedure on a cylinder whose development gives a rectangle.
I was thinking, like a plane, normal to the slope of the cone, text sketch with the number 1 and its graduation shift, apply material removal function to this sketch, propagated to the "tabelle" body only. And finally circular repetition of the removal, in independent copies if possible to be able to change their number independently. Do the same with a min graduation sketch.
Your 1st image gives me an idea. Perform the winding method on a cylinder, THEN apply a draft type deformation but which "tilts" the graduated side, by tilting the engravings with it.
But maybe it would distort the profile of the engraving, making it less optimized for machining...
ah maybe since 2020 the cones are taken into account, I can't get under 2019. On the other hand, it is not a cone, because it is on a radius of 300mm. (see the sketch at the beginning of the post)
Hello @tous @Zozo_mp, I don't have enough experience on the use of the function, I won't be able to tell you more, I don't know any more than you, sorry @FUZ3D, according to the Definition of the function , making a face-spline winding is limited on the entire model, on the other hand it allows the winding to be made on any conical, sphere or domed surface, @laurent. W, it will allow you to engrave the numbers properly on the surface (one by one if necessary), for the graduated I strongly recommend a sweeping removal and a repetition since it is more precise and also the shape seems to me vivid where make,
Thank you for your answer Fuz3D , in the past I had done the same process to engrave on curved surfaces but the result was not always there so I stopped for several years this kind of details to focus on the internal elements of the rockets (operating principles/armament/...).
Hello For your information, this subject inspired me and I started programming a macro to generate tick marks, classic, linear or parametric from an excel table (which I created using the data from the table provided in this subject. Excel file in pj for all useful purposes). With the possibility of using lines or rectangles for marking the graduation. I still have to manage the figures.
