transformation imported traces dxf

[fulcad3d]

Hello, everyone.

My problem: since I have developed rhino tracks and I need them identical, the amount in sw as dxf but so result of the thousands of segments that make me unmanageable everything because it slows down a mess.
how can I join the various segments?

Thank you so far to those who can help me.

 

[re_solidworks]

I don't know, I think they have to be made in solidworks, keeping the parameters of solidwoks and possibly, working with sketches as simple as possible. Now if you can also transform/modify this myriad of segments you will not get a light model as if you had modeled it natively.

I tell you how I did the few times I needed to work on profiles from dxf or dwg full of segments:
amounts profile 2d in a sketch of the part then get out of the sketch
recalculate your geometry with string lines and splines temporarily attaching to the dxf reference points.
You delete the dxf or the limit by suspending it by making sure that it has no references to that referred.
open the sketch line, strings and angles with the odds before making changes to avoid the risk that you get stuck :smile: geometry and checking that horizontal and vertical segments have the respective bond.
modify quotas by setting precise values
change the splines as you need, possibly by controlling with the dxf sketch reactivated but holding down....I don't remember now if it is ctrl or shif to have the snap to the only temporary points.
End.

longer to explain what to do.
as far as possible tries to avoid working on two different cads at the same project

Hi.

 

[re_solidworks]

the button to avoid autosnap and ctrl. in the end it was done first to do it directly in swx, if the rpophile is complex it takes its time.
time ago I did a work of modeling and table with swx in which I was provided with lines dxf in space (on the 3 dimensions) that I had to keep good as axes of my profiles (it was an output of a fem).

after several tests and various phone calls to the assistance I decided to remake everything from head, measuring in dwgeditor and copying in swx. with the import (repeat in 3d) I did not leave, also because the model was very complex.

I told him a few days ago to let go of the 2d files of rhino, but it is seen that the drunkness of importing and working s u geometrie "stupide" will have its own charm... :smile:
when I happened to have to do it were relatively complex 2d profiles and recalculating to flight coon the autosnap turned off then requota them accelerated not little work, also because the dwg also had the odds so I made very early to requote in swx.

I think it's the procedure to follow..... .

I associate myself with what was said by marcof and re_solidworks: better work directly in solidworks without going before for another software! ! !

Good morning and hello to everyone, personally I never had problems in managing imported sketches. working mainly in 2d happens that to speed up some operations, weight calculation, sections or complicated projections, I agree to make modeling in 3d. in these cases amount the most convenient sketch from dwg (other formats I never tried them) and insert the automatic assignment check of the constraints that I find them beautiful and ready when I go to define and complete the sketch.
all elements remain as they were set in 2d, so lines and strings remain such and do not transform points or splines.
the only drawback that can happen is that the sketches are not completely closed or have overlapping lines... but in that case you have to torturewith who designed the dwg

 

[fulcad3d]

What to say.
Thank you all.

But we're not here.

This is the situation: I have a lot of work done on rhino and for various reasons, I have to transfer it to sw of which I am not yet very practical.

the way to paste a dxf on sketch and recalculate it directly into sw, I have already tried it, with long times to realize native clones in sw, with approximate precision to the original and big problems of total definition sketch.

If it were little material, I wouldn't even bother and I would do it again from 0.

I place you a dwg of a track that if you return me quoted (decide your odds, just keep the proportion) and defined with an acceptable solution, I will be eternally grateful.

but from your premises, I count little.

Thank you.

the file I posted, if I put it in sw, it creates a track with a number of low segments, but on the internal path I can not create very internal offsets.

I don't know what you have to do with this blessed profile, but if it comes to extrusion all those fittings you don't have to do them in the sketch but as a solid feature so it's just the starting concept that is wrong. anyway imho is a sketch done very, very bad already inside rhino.
in the attached image see some construction lines in red, vertical and horizontal, which I have quoted regarding the geometry of your 2d. you can well see that casino... the two upper left lines for example are not parallel and neither is horizontal. I don't think you needed the values you see in the odds, do you?
there is not even a line that is such but are exported all as spline, idem for the circles (there will be two or three) so there must also be something that does not read in export options from rhino to dwg.
If all the work you've done in rhino is of this level let go of swx and continue on rhino. putting that stuff right is a delirium

Hi.

p.s. these results are what I have always feared and I still fear contextuals. you run a snap or "slam" against a point of control and you go to give it all cheerful, and then "restaurate" everything is very acidic caxxi

You're not there. :redface:

If you're doing it by hobby, as I understand, take the opportunity and learn to use Good one of the two software. If you decide for swx do everything from scratch working as you should., if you want to stay on rhino and the sketches are made that way... I'm still doing everything from scratch.

 

[fulcad3d]

dear marcof
Let's start by thanking you for the time you lost for me.
I'm actually not a professional but not even a hobbyist in the sense that it's work for me. in fact I invent products that then put in production and commercial in own and in small.
I am sufficiently pignolo to want to realize my models well even if not perfect as they themselves have the only function to convey my idea in details to the moulders and extruders or turn thugs who then usually use them as a departure for the technical drawings that serve them.
you are certainly very good as a designer and/or designer, but given the tone of your answers, a mixture of sarcasm and spavalderia (but not offender because I understand you), maybe you should not bother to help subjects like me anymore.
I mean, you gave me the help, but you're breaking up your trouble, like someone forcing you.
if I appear as the one who makes degraded demands, just say it. Otherwise, since we do not know each other, I would like to have contacts with subjects who bring me the same respect that I bring them.
said this, if you want to explain why it is conceptually wrong to shape an extruded profile in a sketch.

Thank you.

Hi.

 

[re_solidworks]

That's proof I did. after importing the profile I moved it near the origin (for my convenience) with the command moves and then I used the total definition of the sketch.
the sketch is blocked but in case of change it will be a disaster because the rules assigned automatically will never be the ones really necessary for your needs.
when models directly in solidworks it is easier and automatic to assign the correct and desired constraints to the profiles. Consider that the advantage of parametric cads is to be able to change quotas and see the model updated accordingly. Of course, we have to make this work.

how much regulating the management of the fittings... done so, even made inside, it does not suit for 2 reasons. the first is a matter of sketch management, if you miss a mistake following a change of some quota will be difficult to fix it, very difficult.
the second reason is the heaviness of functions. it always works with simple sketches that only one with a complex sketch. you can control this impact on reconstruction times with the "statistic functions" function.
I said that I took a few seconds to get the "black" sketch.

 

[maxopus]

Can I?
the problem of the sketch posted is classic dwg exports many years ago.
the entities (lines, arches and splines) are exploded in hundreds of segments and this involves a series of problems for the management in the cad, because if a sketch is composed of 300 entities keep control in phase of change is a delirium, you lose the days above ... then so much it is worth repassing for good, eliminate the fittings and recreate them in solid mode.
it is also worth dividing the sketch in different works.
a council that I can give is to try to export from rhino the iges of model 3d, generally it is more coherent and less problematic than export in dwg.

 

[fulcad3d]

Thank you, King.
But I can't open your file. It tells me future version.
I use sw8.
Maybe you have one more recent?

dear marcof
Let's start by thanking you for the time you lost for me.
(cut)
you are certainly very good as a designer and/or designer, but given the tone of your answers, a mixture of sarcasm and spavalderia (but not offender because I understand you), maybe you should not bother to help subjects like me anymore.
I mean, you gave me the help, but you're breaking up your trouble, like someone forcing you.

no one obliges me to answer, download a file to try to change it etc, so if I did it it it wasn't to mess me up.
I wrote what I saw opening your profile, and what I saw is an unmanageable fact profile and anyone who should make a mold rather than an extrusion thread should do it from scratch: there is no orthogonal line to the other, the fittings are not in tangency etc. etc. all those who opened your schetch made you, in essence, the same observations. probably in rhino you drew it without curing that certain geometric conditions were maintained. I say "probably" because it's not that you're trying to make us understand why the dwg of your profile is in the conditions we could see.

if I appear as the one who makes degraded demands, just say it.

You're exaggerating me, but do as you think. You can't ask me to tell you that that 2d is good because it's not.

Otherwise, since we do not know each other, I would like to have contacts with subjects who bring me the same respect that I bring them.

I'm sure I haven't failed to respect you, unless you consider lack of respect to give you advice and make you those that I think are also quite serious errors like that of wanting to apply the reforms directly in the first modeling phase

said this, if you want to explain why it is conceptually wrong to shape an extruded profile in a sketch.

When I put you back in the terms that I quoted it because you didn't specify what you had to do with that profile, so I guessed. for a loft between two deeply different profiles the fittings in the starting sketch there must be, for an extrusion it is better to put them after as a feature apart, as it has already remembered re_solidworks.
What do you need that sketc?

Moreover you have not answered us about the errors of orthogonality, parallelism tangence etc that are in your sketch, which in fact make it almost unusable inside swx, as you can well see from the sketch completely defined by re_solidworks. so: do you really need angles of 90,013103° & c.?

if your models or profiles have to go to someone who uses them to make molds or trafiles so much that they are done well, unless you prefer to pay to the molder fior of quattrini to put back in place or to remake from zero models with errors or unusable.

Hi.

 

[marcof]

Thank you, King.
But I can't open your file. It tells me future version.
I use sw8.

Attached the image of what you would see if you completely defined your imported sketch. as you see it is incomprehensible.
If it were made native in swx of quotas there would probably be less than a tenth and would be positioned in order to make immediate understanding of what they go to change.

Hi.

 

[re_solidworks]

basically importing profiles made in this way is a concept error. for me it is difficult to give you advice because I try to work as smoothly as possible and in this direction I have no great experience: I tried, I thought the approciation was wrong, and I dumped it.
I also used autocad before swx but the choice to change was a radical cut with the past.
I do not know what to add, there is no way of doing qualitatively acceptable work with such a procedure.
i because of this methodology you only know them and we are probably underestimating them. However, all you can do has been quoted and demonstrated, if you are doing it with these few tricks, or you have to make the decision to change something you had thought.

 

[re_solidworks]

I am using 2009. however the automatic quotation is also in 2008. as I told you see "total definition of the sketch".

Hi.

 

[fulcad3d]

Marcof

Your advice and comments are very welcome and thank you!
Let's say I felt a certain sarcasm. chapter closed.

for the sketch instead I will tell you that the axes actually are not orthogonal even in rhino and I did not notice. It's obviously like you say: the snaps got me!

Anyway I'm colliding with sw where everything is more complicated than rhino.
And I am aware that if I want to insist on sw, I will have to do a little more because the imports of lines with iges or dwg, it gives me some difficulty.

and anyway I ask myself: Are you telling me that if I have to make an extruded piece I must first extrude the outer perimeter and then remove the various internal parts or even worse extrude a parallelepipedo and besides to remove the inside, also remove the external fittings? (which are not always at constant radius)

I feel like sw because in rhino this is a snap of my fingers: design easily the 2d and extruded; then if the 2d is to correct I will destroy

I am a bit confused

thanks also to the other councils in particular to kings.

Thank you.
