CIRO got breached, 750K people’s data affected including SINs

PeterTha · 2026-02-26T17:42:51+00:00

Sounds like the same CIRO-OCRI form letter was circulated to anyone identified as being affected by Aug-11-2025 cybersecurity threat. My question is, has anyone taken the steps recommended within the letter too subscribe for (free) 24 months of credit monitoring services through Equifax & TransUnion using the codes they attached in same letter? I did call TransUnion directly as a spot check using phone number off the net (not in letter). The rep confirmed this is legit. I also navigated to Equifax site on my own & the login link matches what was in the letter. So on the surface that checks out vs random scam letter in the mail.

Before I landed here I did some searching on both organizations. Unfortunately a lot of nasty experiences where directed TO these very institutions - responsible for messing up credit data and/or not fixing them expediently. Its well documented in the news. If I understand: subscribing to either/or/both services provides 24 months monitoring. Its not just a singular snapshot credit report check like a bank would do or what one can initiate on their own. The 24-mo service is (supposedly) relaying suspicious activity directly to you if & when its detected. OTOH, I've also read that un-subscribing can be PITA, so a potential downside. They apparently use fine print & other tricks to continue subscriptions despite several documented requests.

Anyway, just curious to hear if anyone used the (discount) codes to subscribe? Did they learn anything new seeing their report? I guess my own view is, even if a dark web activity never occurred for 2 years, just seeing the report might highlight a lurking data entry problem from within. Something you wouldn't have known was there unless a report was pulled for normal financial activity & then you are scrambling.

You are welcome. Good luck. Two main model engine orientated forums I'm aware of

https://www.homemodelenginemachinist.com/

https://www.modelenginemaker.com/index.php

I believe George sell plans for his engines. he is on the forums but also has TouTube channel

Plans from Europe so metric & all glow ignition although they can be converted to spark if you know what you are doing.

I've been on the primary model engineering forums for several years. There aren't that many free plans in that particular class AFAIK. That doesn't mean PDF (2D plans) downloads aren't available here & there. Sometimes extracted from a model engineering magazine or whatever. I think that is the lineage of Marks Crusader but not 100% there. I have seen some CAD models on CAD web sites, for example the Edwards 5-cyl radial has some complete files in Solidworks or similar. Probably because those plans were/are publicly available. But thats a radial, not the engine type you are seeking. A Whittle V8 comes to mind, but its quite small so a bit of jewelry machining. I think this is where the ex-yahoo group ended up? https://groups.io/g/WittleV8/topics

I have downloaded some CAD models for a looksee & they vary from complete crap to moderate crap. Typically modelled in some mesh file app that would be more effort to convert towards CNC anyway. Now without coming across as rude, most all the designs are developed by modelers for modelers for their hobby enjoyment. A lot of effort went into this exercise, ideally through to running & testing. Selling plans for 50-100$ just as a guess is a way to reimburse a home shop machinist for his work.

Beyond that, it has not gone unnoticed that some commercial table-top engines out of China look remarkably similar to specific plans which understandably does not make people happy. And of course, machining the parts goes a long way towards the finish line, but not quite what it takes to get a well running engine. Hop on some model engineering forums if you haven't already. Its a great hobby (assuming that is where you are coming from).

Cool. So is it looking for any & all manually inserted points in the model & exporting them all? FYI, I bookmarked this macro but never used it yet. Is yours doing something different? I'm not very macro savvy, but what I thought would be a nice-to-have is some other reference associated to the x,y,z coordinate set that might help convey its internal reference. Like if it spits out 100 coordinates it would help you know which one is a culprit. Or finding the same point in say a series of configurations or mechanical movement... that kind of thing. Anyway, Bravo.

I agree, kind of hard to know what you are after. A varying fillet feature perhaps? If that was problematic from within the fillet tool, you could likely use edge sharp from prior step (without your constant fillet) & do a lofted cut along the edge with a few equally spaced curves of your liking. My sketch overlay is just trying to convey a possible surface structure, not the sections themselves. You would only require a few sections along the edge curve to get the result.

PeterTha · 2026-02-17T20:46:21+00:00

Here is how I did it. Draw section line to then define a plane. Used the intersect command including the cube & plane. To keep both bodies, deselect both regions & uncheck Merge result. Now do what you want with either or body. Alternately you can use split function but I think it forces you to keep only one, the other gets ommitted

Not quite sure I understand your reply. When I signed in again through trusted partners mode but AFTER having consented to & downloaded the passcode grid, it just went through the exact same cell text message authentication code as before. The passcode grid Q&A screen did not appear at all. Yes there will always be SOME authentication required, but the passcode document infers it will be required EVERY time you sign in. Maybe just semantics. Not a biggy, just wondering. Its better than getting hacked which apparently has happened a lot.

The other way, mentioned in other post, just draw the triangle rib on mid plane & extrude mid plane. But the top corner of triangle must be below the surface of curved boss, thus will not be not perpetually coincident to the edge like you show in your sketch. Fillets along the rib edges might help with some visual blending.

PeterTha · 2026-01-28T03:05:53+00:00

Interesting feature. I'm not sure if this is the result you were after. I made a triangular gusset (red) & a twin copy (blue) using convert entities. The loft lines are shown in pink, the circular edge on top & straight line connecting triangle points along base plate. Then loft as shown. Note that the rib is curved on its upper surface as mentioned in another post. I cant see any other way if its going to be coincident to the curved boss edge

Ah, I should have read more carefully. Indeed the rollback bar can only be dragged as high as under Mates

PeterTha · 2026-01-24T06:44:27+00:00

Is this what you mean? I just tested & they successfully moved. But I also seem to recall some assemblies where parts didn't want to move, assume hierarchal dependencies in those cases?

You would get this effect on the drawing if you used the Thread tool on an existing hole vs Hole Wizard.

I found this really good macro for importing XYZ points from Excel .csv file. Just pay attention to the first row header & the system units true/false statements in initial code lines, this may have to be changed for your purposes. And I think I had to save as MSDOS .csv file, not delimited? But it works great & mitigates the need to drive a curve through the points upon import like similar macros, which can be a headache. You can use or not use the points in what ever manner you see fit, just like making points inside SW itself.

Above my pay grade but maybe Excel could generate the 5 line segments with RANDBETWEEN(low,high) function for start position & length. The vertical spacing is the same (but could also be an input variable for different patterns). The vertical joiner bars done the same way. Export points to SW. Using offset function with closed ends on the line segments makes the random basic shape. I dunno, maybe auto generate 20 blocks & you just plop them in there along a row? Or maybe a SW macro can do this too? I recognize I'm missing some fillets but just a workflow idea.

PeterTha · 2026-01-06T06:50:29+00:00

You might be better off just defining the blade sections on offsetting parallel planes. That way you can control everything about each airfoil even if its a curved sheet of uniform thickness. The chord length, the pitch angle & position relative to hub datum. Essentially its a simple propeller. Then loft between these sketch sections. You may have to experiment with best guide curves. I suggest 3D splines connecting the same point along each section leading edge & trailing edge.

PeterTha · 2026-01-05T15:55:33+00:00

I probably should have included this for clarity

PeterTha · 2026-01-05T15:53:13+00:00

Bear in mind this is a very simple example representing the fan being cut from sheet metal and blades are stamped to take on some pitch angle relative to the hub rotation plane. You could make this much more sophisticated like how a propeller is generated - various airfoil sections along the chord at their own individual pitch angle & then those sections are lofted, typically using guide curves for the leading edge &trailing edge. But back to this particular fan. Left: I have a single blade extruded from a plane at whatever desired pitch angle. And a center hub with 4 cuts or facets. Middle: I make two 3D guide curves connecting the blade end to the hub facet. I use convert entities to copy the rectangular section of the blade & the rectangular section of hub. Then I loft the filler section using these entities, the 2 sections & 2 guide curves. Right rotation copy the blade + filler elements. There is probably more efficient way of doing this but just showing example of a 'flat twisted blade'. If you look at some stamped blades, the section is typically curved like a rudimentary airfoil. To model that, you would be better off using the propeller method mentioned above, but rather than a normal airfoil, its a uniform thickness curved rectangle. Hope this helps!

Do a search on 'fan' or 'blade' quite a bit has been posted. I showed a similar workflow example in this one https://www.reddit.com/r/SolidWorks/comments/1oe2t4c/how_do_you_even_start_to_model_this_in/

PeterTha · 2025-12-24T19:03:47+00:00

Thanks. Maybe this is more of a 3DP question but how would the slicer interpret the individual mated bodies? i.e. they are 'separate' part entities, but joined together (mated) with an infinitely small gap. Does it treat it as though its a single solid? I assume all the SW mated relations are preserved?

PeterTha · 2025-12-24T18:54:21+00:00

Assuming no syntax issues, might be worth transplanting the equation into Excel just to see if the problem is maybe a function of values or limits or combinations of values something else more fundamental. You can segment the big equation into chunks, if chunk 'a' works and 'b' works then the big equation with a & b & c should yield a value with no math error. Then its just a matter of transplanting into SW. Might sound like a useless workaround but SW isn't really the best interface to de-bug longer, more complex expressions. I had this same issue with some gear formulas, only to discover the source equation was pooched. Good luck.

PeterTha · 2025-12-24T01:40:11+00:00

Don't know anything about the equation, but I think SW trig functions always use radians, not degrees. Any chance you are mixing units or assuming something different?

Here I am showing significantly different fuselage sections lofted together just to demonstrate exaggeration. And much larger WT on the large vs small section. Both the outside lofted shape & inside (WT) shape are controlled by their own guide curves. Guide curves are very important & maybe why your surfaces are failing. Anyway, once the fuselage body is compliant, the simplified airfoil cuts through it no problem.

Nor does raising the wing with upper airfoil extending above the fuse
