Hi,
I need some help with 3d construction software.

I need to make a 3d model out of a 2d shape by rotation it around one axis. I have this shape and I want it to rotate it 360° around the y-axis to build a volume.

Can somebody recommend a free software to do that?

I think Autodesk 123D Design should be able to do that: http://www.123dapp.com/design

Sketchup

Clara.io Should be able to handle it for free and its also web based, nothing to download.

I highly recommend @FreeCAD . If you decide to try it and get stuck let me know and I will help out.

Of course most programs like LightWave 3D for example, have a free trial that you could use as well if it’s just the one thing. Here’s the LW Trial

And here’s a quick tutorial on just what you’re doing.

SketchUp with follow me tool

@Thomas_Sanladerer I didn’t find a way to import 2d drawings into 123 Design. Do you know a way?

9

@Joshua_Porter Do you one that describes what I want to do (= make 3d objects out of 2d shapes)?

10

@Phil_Nolan I will try it. Can you point me to some information how to do the 2d-3d conversion?

11

@Daniel_Wood I already tried FreeCAD but didn’t find a way to import the 2d file without it getting changed to a complete different shape. I will try it again an maybe ask you for help… :slight_smile:

Have you tried with 123 Design for autodesk? I think that is the best alternative, if not try with Sketchup.

Have you checked OpensCAD? it has the ability to import DXF (I guess you can export from CorelDraw since its vectorial) and you can easily rotate.
It’s script based, however. But you just need a couple of lines of code. And then it’s repeatable with any other draw, just load another DXF file.

You want to use the revolve tool. This link should give you an idea how to do it in Autodesk 123D

@Chris_Lau But how do I import the 2D file?

16

@Kai_Laborenz You need to export the drawing to .DXF file. You should be able to open the .DXF file in Autodesk123D

17

Actually I can’t - we’re speaking about #Autodesk 123 Design in the free Version, right? I have tried both the desktop version (there is no import at all) and the online version. There is an import option (but not for dxf) and when I use it the shape is conferted to a 3d object instantly and I cant use the revolve tool anymore…

designspark mechanical is free http://www.designspark.com/eng/page/mechanical

@QCAD1 the best way To go then export it to @SketchUp build it up from there…

openscad: rotate_extrude(…) import_dxf(…): should do what you want.
