Please excuse my ignorance but what is a Draft Angle?
Have you checked Rhino help?
http://docs.mcneel.com/rhino/6/help/en-us/commands/draftangleanalysis.htm
Draft angle is often used to design injection-molded parts that must eject from molds.
The draft angle depends on the construction plane orientation. When the surface is vertical/perpendicular to the construction plane, the draft angle is zero. When the surface is parallel to the construction plane, the draft angle is 90 degrees.
The pull direction for DraftAngleAnalysis is the z-axis of the construction plane that is in the active viewport when the command starts.
|Changing the construction plane before using DraftAngleAnalysis lets you define any direction as the pull direction.
Thanks @Mahdiyar,
Thatâs usually the last resort, the âIf everything else fails RTFMâ kinda option
Shame. Lots of smart people have that attitude; makes them into smart alecs. Please donât admit to this publicly. McNeel puts a lot of effort into their help and itâs overall pretty darn good. They sure donât need any excuse to reduce their effort because they think their users find it a last resort.
Listen, Iâm proud of that. My curiosity usually transcends beyond whatâs written in some Help or Userâs Manual by people with limited overview of how a certain functionality could be used, leading to much larger knowledge and skill acquisition.
Help/Manuals and Tutorials provided along with a software are boring. Iâm more of a hands-on kinda person.
Dude, you work in some sort of production and had to ask a support group what a draft angle is. Donât get cocky about your curiosity âtranscendingâ anything.
No!
I was not familiar with that English Term, Dude! Iâm not a native speaker, I did not study engineering in English.
You post enough here that we all have a pretty good idea how smart you are and how proud of it you are. In this case I suspect that you were already quite aware of what a draft angle is but just didnât know that âdraft angleâ was the english term for it. In this case the help which you so haughtily disdain would have told you instantly. Those of us who make use of the help really do want McNeel to keep up their effort. We really donât want their dislike for mundane development activities like improving fillets and blocks to spill over into ignoring the cries for good help.
exactly!
Just as an addition. Any exterior and interior car part has to be easily releasable from the mold. This is why any part you see when looking at a car has a draft angle of at least 3 degrees. Some metal parts can be released at 1 degree. Some need even 5 degrees. Without this analysis you wouldnât be able to validate this on a production model. Very fundamental analysis. Great its finally in there!
Also, draft angles should be homogeneous or gradually in- or decrease. Strong Variations in it indicate bad surface flows. Draft analysis, at least in Icem Surf can also be misused to easily spot wrong surface normals. Since I donât have access to Rh7, I donât know if its surface normal dependent here as well, since this rather a shader issue.
Listen up kidsâŚ
- If you have something constructive to add to a conversation, please do so.
- If you arenât familiar with a term, ask.
- If your comments are not constructive, then do not post them.
Itâs not that hard to behave.
Entformungswinkel = Draft Angle
Abstellung = Flange, Taper Extrude
To be fair, the term draft angle differs widely from the german term and the term in german is actually not very known, even to engineers. I do understand the confusion with this one. @martinsiegrist I donât believe Google helps here
To add to that, Bulgarian Engineering is a mixture of German, Dutch (especially Ship Design), French and Russian terms.
Pretty much every expert brought to Bulgaria after its independence from to Ottoman Empire has brought the terms from their languages.
Draft - on the other hand is such a broad term that you canât simply understand by reading if youâre not working exactly that or have studied in English.
If only that was an easy task, to search for a German word relying on Google Translate A.I. It is a technical term assuming a word with 10+ letters.
Thanks @TomTom
I still have to find a German engineer who doesnât know the term âEntformungsschräge/Entformungswinkelâ.
I am not holding my breath.
Sorry if google didnât help youâŚ
Well if you deal with molds or construction in general you know for sure, but I doubt a naval, structural or electric engineer will necessarily know.
This has been my impression, I mean they could guess right after hearing the term but the other way around its not clear that draft angle is equal to Entformungswinkel⌠A direct translation would be âZugwinkelâ and this could refer to anything mechanical.
