For the Standard Optics Table / Board the Holes follow Industry Standard Fastener Size of either 1/4 in. Threaded in English Units or 6.0 mm Metric Threaded Fasteners. Now that number is the Nominal Diameter of the hole or Fastener and is what it should be modeled at. Period. I say so we are all modeling things to standards. That is some nice work there !

Hi, The general Rule in 3D CAD Modeling in Professional Software regarding Screw Threads is this: We do not model them because they eat up horrendous amounts of memory which we need. When there is a Cosmetic Threaded Feature command as in SolidWorks or other software we use that. If fake threaded feature does not exist in the software then we leave it as a hole. Another way I've seen it done is there is a hole of Nominal Size and then a dashed circle of thread size at the face; that way it is understood by all that it is a threaded hole or bolt. And the size can be acquired f/ the model w/out even asking, which I thought was pretty cool! Now not everyone in industry has adhered to this standard but that is best practices. Otherwise as on your part you'll have a grid of holes each with a threaded feature and it will try to render them all. Yeah ! Now in industry the standard threaded hole is indicated by a double dashed or hidden line on drawings. The threads are not drawn unless and this is the exception the threads are really LARGE (lol). Even then you can draw like a few on each end and put a phantom line connecting them to avoid drawing however many threads are repeated over the length.
Thank You so much for this valuable add on. I am beginner and starting learning of blender. from last 2 day i had been trying to create spherical mirror effect but i could not do it. finally I found your video So heartly thank you for this. Please give me suggestions how can i start my journey?
Can we make a rainbow effect when light passes through a prism with this addon? For example in cycles with nishita sky and sun or any other light source?
Rainbow effects are not a feature of this addon, but of a Render engine such as Cycles or LuxCoreRender. The keyword here is spectral rendering, or dispersion. LuxCore does support it with its glass material. For cycles, AFAIK it is not yet available but comming. OptiCore only has the purpose to efficiently generate the geometry of optical elements. Not material or light properties.
Hi I'm trying to model a solid catadioptric telescope where two of the four surfaces are mirrors in a solid glass object. I'm having trouble getting the mirrors to work and would appreciate if anyone knows how to put the mirrors on one part of the surface? If anyone knows how to do this I would appreciate it. I have the geometry and the 3d model already just trying to figure out how to get the mirrors on part of the surfaces.
You can go into "edit mode" by pressing the tab button in Blender. There, you can select individual faces and assign separate materials to each face. You first have to create the differnt materials and add them to the object (in your case one glass and one mirror material), then assign them to the faces in edit mode.
Thaks for your long and detailed comments! Regarding this question, the menu unfortunately can't be accessed again after the model is created. This is standard Blender behavior in that regard, as a consequence of it being vertex and not parametric based modelling. because you can then edit any vertex in any way, this would break the geometry away from some mathematical model, and storing the parameters makes little sense. There are already requests to implement the ability to change the lenses afterwards, but it would need some custom implementation, and I did not have the time so far to dive into this. But it is not forgotten.
@@howtoprint6002 Oh i see! i ended up just making my own with some circles extruded upward, sorry i am just seeing this response now! Great news ! i got an anamorphic lensing system working in blender, you should check it out! I used your program to generate two spherical lenses for a variable diopter set. I hope that is alright with you. ua-cam.com/video/F2cfuNXPfFo/v-deo.html
Is this still supported? I tried downloading it and couldn't get it to load in Blender 4, 3.6 or 2.93. Traceback error in the preferences add-ons menu.
@@letskirschjoghurt7359 ua-cam.com/video/3vJ9WZXZW2k/v-deo.html I made a short video showing what's happening. Error happens when I try to enable it in preferences. I screen-recording this on my Mac, but I'm getting the same error on PC.
@@gopalshah Good idea posting a video, that makes it very clear! Indeed, this 1.0 release version I made some time ago is known to cause this issue. You can better download the addon as the "latest" package. See this issue on GitHub for details: github.com/CodeFHD/OptiCore/issues/17
Sorry if this replay comes late. In principle yes, this is still active, but I have had little time for it lately. I don't know much myself about modern anamorphic lens designs. I do know that some designs use pure cylindrical lenses to acheive the anamorphic effect. These can already be added as part of the "Square Lens" feature
Thank you so much, I’m trying to make a working pin hole camera in blender, and this was a life saver

Nice ! Could you explain how to create the laser beam source ? Thanks !
Hi, hope this will still help after a month... In LuxCore, Laser is hidden as an option to the "Area" type light source
What is the Menu when you first bring the model in I would like to access that again.
Not that great a Blender.

Any chance for cycldrical lens implementation?
Cylindrical lenses are already available under the "Square Lens" object

HI @@nilsmelchert776 did you figure this out? Currently also in need for that. Thx in advance
Hello how to get the laser beam
The laser is a part of the LuxCoreRender Engine. There, it is an option to the 'Area' light source
@@letskirschjoghurt7359 how can we download that engine
are you german?
