length sketch entity

[Pablo]

Hello, everyone!
as from title: I would need to indicate at the table the developments of some sketch entities, mainly of arches, but not only. As you can see in the posted image, I must indicate the development of the ab arch and then the total development of this curved tube. I have created an equation that calculates the development of ab. It seems to me that it is possible to trace back to the properties of entities, therefore without creating twisted equations. but I don't remember how (and if) you do.. Could someone help me? In practice I should know what the lengths of each of the entities of qs. sketch, then create a single equation (summary) in which I insert the entities that I care about developing. Thank you!

Isn't it okay if the selections and the mixes?

Hello, King.
Of course it's fine, but I have to configure several versions of that arc (and other forms) and I would like to automate everything.. I could write a 1 page long equation, and I would succeed, but it would seem very simple to "capture" the values that sw shows you when using the meter and insert them into a trivial algebraic sum. . .

I'm sorry, I may have misunderstood, but don't you just have to sketch the length of the bow?

in part you (among other things I do not remember how you do...), but having to sum up arches and lines and having to indicate the development would be nice to make it sw and not to manina!!:redface:

Okay, maybe I'm trivializing, but you sketch the central axis of the piece (or even not central) then the "extrude" in a symmetrical way and do the flat view, you find yourself with the development of the sheet, is that what you meant?

but it's not sheet metal... and if by chance you mean to create a part of sheet with that profile x then get the development.... let it go! !
I have to find out where sw locates the geometric parameters of entities: in practice the value that makes when measuring 1 or + entity with the instrument "meter". . .

 

[cacciatorino]

try to look at the attached file, there is a trivial equation that calculates the perimeter (except the two sides of the thickness) and then divides it by two, see everything going to edit the equations.

However for that piece I think the best thing would be to do it from sheet metal, at least you can try to take into account the development variations due to bending.

 

[Pablo]

Thank you, hunter, but in that way I could well calculate the development by inserting quotas on lines and arches... But in the end, thinking about it well, if I quote all the strings and all the lines I'd be fine, right?? I do not remember however how we quote the development of an arch.... Can anyone tell me?

final arc/point end arc and then the arc itself.

...

Why? What made you the sheet?:biggrin:
It would be so simple. .

that if it is not sheet metal (or any object "flatable") you need development? (maybe you need to know the length of the "path"? )

If you could do it in sheet metal in the part you automatically create the "developed" configuration. enter into that and the flat model quoti the length; that value you can then use it in equations without further calculations.

a fictitious line for the support of a quota, a simple equation and a new property that is updated automatically. :smile:
download the attached file, it is already parameterized, from that you can understand how
I did to make him calculate the development.

it is not a matter of knowing or not to use the plates, if at every small difficulty you must
Find alternative ways not really orthodox, you know what mess after a while you draw?
you find "finti" files with improper functions (azz... on me attacked his illness :finger that recovering them after a few months you do not squeal anymore...
examines the attached file, it is nothing of that, I arrived with a minimum reasoning and exploiting the tools I know. :finger:

thank you mike, and thank you all. Now I'm not in the office, in the morning at dawn I will open your "tubo.rar", always in version 2010, and I will see what it is.
As for the advice of creating a function of sheet metal, I do not find it so simple, I meant a very basic thing, that is to sum up the values that in sw are already there and are hidden somewhere. so I tried to quote all entities (archies and lines, even with piloted odds) and I created an equation that sums them all... the game managed!!! Obviously, depending on your needs, you can insert all or only some sketch entities! Thanks again to everyone. I'll get you something tomorrow.

Fuck her.... put in the avatar version of the sw.... look at the time...
I had to remake the model with 2010.
Anyway, it's worth the above.

And you're right, mike!:frown:
in any case your "tubo" is exactly as I did last night: you quoted all the entities and summed them. the shortest and most logical way, according to me...
Thanks again!!

Don't worry.

I think it's the right system. :finger:

I am sorry if I reassemble this discussion, but I am putting into the table models of external origin, which I cannot change.

I should calculate the approximate development of folded parts. I thought I'd tell swx the perimeter of the net section, and then divide the value obtained by two (subtract the thickness of the sheet obviously). Is there really no way to have this solidworks perimeter if not by hand adding all the various edges? I also tried to verify the properties of the extruded section area, but among the data that I am given this perimeter I cannot find.

in the tool menu check just go to measure and select the sketch perimeter or the lines/curves that interest you. will tell you the total length of selected segments. this in general for each combination of selected curves/bords.

but if you want advice, you will have a wrong length. you better make a quick extruded sheet and let it develop with a k of about 0.34. Keep in mind that the only fact of changing knives changes the length of development a lot. Unfortunately I am not very "practical" in the folders.

It's already done, so don't put me back on them.

I'd already used the solution you'd indicate, but it takes a long time.

thanks for the directions.

..I should calculate the approximate development of folded parts. . .

You should see how these parts are (you can't post a file.. even just a similar example made by you?). Are they originally shaped with the sheets? in this case you already have in the file a developed configuration and the size you take from there. you can also put the table directly flat repetition, if you don't need to hide the view after you have connected/concatenate the size maybe in a text note.

if they are simple solids you can't use somehow the sketch and function quotas they used to model them? you could add a property/equation that sums you the size of your development.

Still,
without modifying anything or having to remodel a sheet; starting from the assumption that up to a certain thickness (which you have?) the development is given by the sum of the internal sides, you can trace a sketch (which you will hide) that "recalc" the inner profile of the extruded. the quoti and uses it by property, equations and everything.

the systems are more than one, I repeat that we should see the "subjects" :biggrin:

ah.. if with the tool measure Touch the edges of the profile by holding the ctrl automatically gives you the sum of the sides/curves that make up the perimeter. You do it on the inside perimeter and you're fine.
