Drawing a mechanical weld from a spline in Solidworks

3D Design Volume Model
1

Hello

 

Do you know how to make a mechanically welded part from a spline in Solidworks?

 

Indeed, either it is impossible to recover the trajectory from the spline.

Either when you play with the basic DXF and DWG files, you create huge discontinuities or breaks in the mechanically welded element and the bending radius is no longer recoverable.

 

FYI, the base file comes from abode illustrator.

 

Does anyone have a solution or a trick?

 

Transform the spline or retrieve the spline data?

 

I tried with a balayage, but I lose the properties of mechanically welded.

 

Thank you.

In mechanical welding, you need a library of elements (parts) (profile sketches)

 

So create your part library

 

and retrieves these parts to insert them into the mechanical weld assembly

Yes, thanks gt22, but how to make these profiles follow along a spline.

 

The problem is how to use an imported spline curve as a scan line of the mechanically welded profile.

 

Thank you.

Hello In my opinion, it is necessary to transform the spline and arc and line. see if a macro or utility exists... @+

what is the type of curve you need to make

 

can you make a screenshot

 

The advantage of the welder mechanic is the quantity of the elements (monenclature)

if the sketch library has been made

 

 Your spline can be made via deform tool on a straight lambda section

You create your right part and with your spline sketches you take the deform tool

Ok, Coyotte, but the work is long and almost impossible given the number of different departments to be reworked.

 

Thank you Tomalam for your contribution over the long term.

 

Here, for example, is a spline sketch to be transformed into a mechanical weld.

And where is this tool deform please?

 

Not sure it works with a mechanical-weld

I just saw your drawing

What's the problem?

you divide your room in 2 since there is symmetry put your axis of symmetry

you put your spline on it with as many points of coincidence as the need is felt, the less you will do the better, it will be afterwards either you make a shift for the thickness of the profile and you symmetrize

Is it for irony?

Yes, that's why I was asking if anyone knew of a macro or a utility to do it. the idea of GT22 seems good to me @+

Hello

 

A priori it is not possible.

 

A roundabout way is presented here:

Or on the official SolidWorks forum:

Hello

 

Did you try to recover your spline via a sketch?

You create a sketch parallel to the imported spline, you select an entity (1 end of arc or line) then you do 1 right-click and there must be a command like "select the string" or "select the loop" (sorry for the approximation on the terms but I don't have SW at hand). Then you make a copy of edges in your sketch.

Once you have a piece of sketch, you should be able to do whatever you want with it.

Hello

 

Thank you Lucas Prieur, but it's not very clean and it prevents me from recovering the properties of a "cut-list", but thank you for your contribution, it confirms that it's not possible. 

 

Chamade: yes, I tried, via shift the antequalities with a shift of 0 or very small. Then, I tried to copy the antis, which doesn't work. Then, I also tried to convert to DXF and DWG, with the option "convert splines to curve" with the option "Solidworks", then insert into a sketch but here it's mini-segments of lines that I get and it's unusable for me, unless I manage to smooth them out. ... and to have excellent continuity between the line segments.

 

--> What I need is to be able to recover the radii of curvatures of the forged or mechanically welded parts to send to the production with the properties of the parts such as lengths, linear mass, etc ... and the cut list.

 

These parts come from the designers (and they let themselves go a little) and they have to be ironed on SdW, to make 3D and drawings for the boilermakers. 

 

So I think I'm going to have no choice but to take everything in appoximative rays, and make an approximate trace on top. 

 

So no one knows if SW can retrieve this kind of information to transform a spline into curves?

 

Otherwise, gt22 is a piece of boilermaking, bars to bend to give the desired shape.

 

In any case, thank you all for your help and if anyone knows how to transform a spline into usable information (coordinates, excel file, template, ...) please let me know. 

 

Good evening everyone.

see attached image + file under SW2012

 

so everything is set up but my odds are not good 

in volume and surface

 

 not everything is always measurable the ironworkers often take the dimensions on a scale 1 plan

with a ruler, compass, trace on a sketch and form the pieces on this said sketch

Yes, ok, but you're not in mechanical-welding tab "Welding".

 

And precisely, this is to avoid 1:1 measurement and save time. 

18

In my opinion you won't be able to do otherwise but I could be wrong

or position a multitude of points to reference them via the origin

It's up to you
