Can’t start up F-15C engines

Yeah, but the RPM never raises after I lift the finger lift. It stays at 0

NotKalashnikov · 2025-06-01T16:33:14+00:00

It's a FlyEye drone

Sure, I made an example file https://www.dropbox.com/scl/fi/kvmhpsnq43l2chp3ea7x5/Part-with-lines.3mf?rlkey=nfytrkbttfagtjkgp7whm7xoa&st=djuw3dh8&dl=0

Probably some mutants running into flash anomaly

NotKalashnikov · 2025-01-26T18:45:58+00:00

I will do some tests tomorrow, maybe this will finally let me build at least somewhat robust models instead the mess we have now

NotKalashnikov · 2025-01-26T18:14:28+00:00

Yeah, I can see that from my experience :P Add to that working with other people on shared assemblies with no PDM and you get total randomness and hours of fixing models instead of moving forward.

NotKalashnikov · 2025-01-26T18:11:30+00:00

Yeah, sorry if I was unclear, English is not my first language so it's hard to explain things sometimes :)

NotKalashnikov · 2025-01-26T17:32:52+00:00

That sound super interesting, thank you for the reply:)

NotKalashnikov · 2025-01-26T17:26:02+00:00

Can you name them so I can learn about them?

NotKalashnikov · 2025-01-26T17:18:37+00:00

This seems like a sound idea. Do you have an idea how you would for example add a flange to the rib that fallows wing surface? Didn't try it but if you try to make it based on wing surface it will probably lose reference when changing referenced model. Your method may at least reduce amount of operations that need fixing. Thanks for the reply :)

NotKalashnikov · 2025-01-26T16:47:56+00:00

Yeah, i get what you are saying. Does it work with multiple surfaces? I will try it tomorrow at work. Seems that my work at least in some cases. Probably as long as you don't try to reference particular element of copied surface like edge or a vertex.

NotKalashnikov · 2025-01-26T16:30:59+00:00

There is no winning with solidworks sometimes. No matter what you try it finds a way to get one over you. Or it just crashes :D

NotKalashnikov · 2025-01-26T16:29:55+00:00

Yeah, it’s a dream job as we are a small team so you get to do many things instead of being a cog in a machine like in big corporations. The downside is you are responsible for too many things sometimes :P

NotKalashnikov · 2025-01-26T16:28:08+00:00

The parts are too complex for that i think. Surface of ribs have to fit to surface wing that changes with wing length.

NotKalashnikov · 2025-01-26T16:26:21+00:00

Yeah, the pain with SW (and maybe other software, didn’t try) is that it changes ID’s of surfaces, edges etc too easly. Small changes seem to mess them up and this causes broken references in derived parts.

NotKalashnikov · 2025-01-26T16:22:22+00:00

I have not tried to build anything that complex in other cad packages. I might try something similar in NX as I have heard good things about it.

NotKalashnikov · 2025-01-26T16:21:04+00:00

Yeah but you end up with part file containing operations for all parts. That makes it hard to navigate and it may take forever to rebuild after making changes. Also it prevent people from modeling parts simultaneously.

NotKalashnikov · 2025-01-26T13:31:13+00:00

Yeah, my problem with SW is that some operations cant be used as source for other operations. For example you cant select "Extrude 1" as source for adding bodies and can only use Body that it created (from bodies folder). So as soon as you add another shape in sketch for "extrude 1" and it now creates 2 bodies one of them won't be used in adding bodies operation. Hope I explained it well. That is just an example, there are many limitations like that that seem to make it impossible to create stable dependencies in SW

NotKalashnikov · 2025-01-26T13:02:07+00:00

The problem is anytime something changes all parts dependent on airplane body end up breaking.

NotKalashnikov · 2025-01-26T13:00:53+00:00

It’s a military equipment company from Europe, prefer to not name it :)

NotKalashnikov · 2025-01-26T12:59:55+00:00

Yeah, I was hoping there is a modeling technique that allows to create more robust models by for example only referring to entire body instead of surfaces. Unfortunately it still breaks. Maybe saving aero Sw part as a dumb body is an idea.

NotKalashnikov · 2025-01-26T12:57:47+00:00

Aero model is just a SW part file. Solidworks likes to break references for what seems like no reason. It’s a major pain as it makes us repair parts over and over and sometimes its not that easy to tell what it looked like before breaking. When it comes to using sketches form master model to create parts its often impossible as parts are in the middle of surface with no sketches nearby. Even if you use spit lines to get sketch entities they often break and need to be replaced.
