Import Spline on solidworks

3D Design Volume Model
1

Hello

 

I received a client DXF which is a spline, but when I import it into solidworks I get a multitude of small segments, which is not suitable for laser cutting at all.

Could you give me a method to import this spline into a curve or spline into solidworks without it breaking it down for me?

Thanks in advance

Kind regards

Hello

Have you tried to trace a spline that passes through the different points of the imported spline?

The problem is that it represents a lot of work, I'm looking for a simple and quick method, I found the adjust spline function which works well but when I do a DXF export the laser programming software crashes ...

Hello, maybe not the easiest solution but it is possible to import a spline from an excel or text file. So you will have to export the coordinates of the points and then use the insert > curve menu > xyz points.

For export, see here: http://grabcad.com/questions/tutorial-how-to-export-points-from-solidworks-to-a-excel-file

It seems a bit complicated to me for what I want to do but I'll try...

6

If you can open the DXF with Autocad (or DWGTrueview for free), try copying and pasting the Autocad spline into the SW sketch

7

When I copy/paste from draftsight of the spline I have new lots of segments.

8

Would you mind posting the DXF in question? Just to see for ourselves;)

What is the brand of laser machine??

because normally you find with the software of the machine a software like metal design (for the Amada fo-3015 machine) that can help you

Here is the play

For the machine, we have a bystronic driven by Lantek.

I find it very very beautiful your Triskell and long live Brittany

in dxf it gives a multitude of lines even if you activate the export as spline

I have a bystronic driven by lantec

 

It's true that for the arcs of a circle and spline, he struggles.

 

If you have successfully imported your dxf into Lantek, there is a "fitting" function in English

 

This simplifies the spline as much as possible and saves a lot of time.

just stick an offset surface to it and sew

if you don't want to see these micro lines that are 0.956 mm

Erratum I managed to export it as a spline

Otherwise under SW I did as benoit had told me in a previous post

Right-click selected the channel

then tool/spline tools/Adjust spline, with 0.01 in adjustment

Here is your dxf import into Lantek, simplified, then export again to dxf.

 

From 2.3MB base, I go to 30Kb!

 

A piece of advice, when importing, you should avoid having cartridges, text etc...

Keep only the essentials!

@bart your less line but you have some so you will have a multitude of starting points on a Chinese laser lol

so mine in spline

Oh yes, I respected the original triskell as best I could, I just simplified the polylines.
