Generation and export of 2D drawings - anyone?

[Stefan071]

Hi!
In one of the original articles from Leap71 there was mention that Noyron is also able to generate the production drawings.
this is interesting to me, since I'm working on components that will require some additional finishing/process notes for post-manufacturing.
I am curious if anyone was able to achieve this already with PicoGK, or found another way of doing so without using a 'traditional' CAD environment.

I can't speak to you traditional 2d drawings from picoGK, but based on the what I know about it, that won't be easy or all the practical. However, what you may want to look into is annotations in 3D pdfs. I know it as MBD, or "model based definition" in SolidWorks. Essentially, you take your model, annotate the 3D model with critical info, and save it into a PDF that allows the end user to rotate the model, and view the annotations plus a nice title block for configuration control. picoGK does the hard part of getting you a model, annotations wouldn't be hard especially if you already have CAD like SolidWorks. Alternatively, you can just keep your finishing/process notes in a separate document, control that, and reference the model. Not as neat or specific, but it'll work in a pinch.

Thanks, I haven't thought about 3D pdf's. I do have acces to SolidWorks and maybe OnShape provides a similar function (haven't looked into that yet). A small document export with additional manufacturing notes, like finishes or treatments is easy to do and can be expanded with ease.

Exactly. Today, chances are a tech is going to go straight to the model anyway, so all you need is manufacturing notes and some acceptance criteria for QA.

If you do things right, your CEM will include all the information that you need to document, which includes measurements etc. Our Noyron objects self-document (torque required for nuts, etc.). From that info you can often create simplified graphics that can be communicated.

For 2D "drawings" you will often want to slice through a voxel field and show the cross section.

You can find an example here: https://github.com/leap71/PicoGK/blob/main/Diagnostics/TestCLI.cs

If you want to vectorize the cut, you can use PolySlice.oFromSdf( and pass the grayscale image you first acquired with vox.GetVoxelSlice(SliceNumber, ref img, ESliceMode.SignedDistance.

PolySlice has a function to save as SVG vector format: oSlice.SaveToSvgFile(..)

Again, the best conceptual framework is that the CEM has all the info, it's the full source of truth, so it should self document. At LEAP 71 we output performance predictions, domain volumes for simulation, post-machining instructions,, heat treatment instructions, assembly instructions, helper geometry such as jigs and fixtures, bounding shapes so people can load stuff in CAD. Every time we run the CEM.

Best,
Lin

Hi Lin,

I think that is also the way to go, a sort of 'BIM modelling', but with generated components.
Currently I'm exporting STL and STP and a long list of secondary manufacturing steps, treatment and coatings.
Even though my current model is running on 0.5mm voxels resolution, the smaller details are often in single or double digit microns.
A more clearly detailed 2D drawing with instructions alongside it would make it more readable for a machineshop to actually build it, since the 3D model lacks the fine resolution.
