The 3D component models grew very fast, pushed by manufacturers or open design libraries (3dcontentcentral for example).

The only problem between ECAD and MCAD is that the origin of components is rarely the same in both CAD tools.

After 3D component download, you have first to match this: origin 2D ECAD packages = origin 3D MCAD models. Needs expert and a lot of time!

The 2D ECAD datas are exported as IDF (option of all tools).

Then, peu importe you can use CircuitWorks with Solidworks, FreeCAD with the PCB option and other tools:
- CircuitWorks and FreeCAD over IDF import with the restriction that you cant import the complete PCB with trace and so (IDF < V4)
- FreeCAD gives you the option for directly EAGLE PCB binary import (*.brd files) with trace, silk, its really amazing

The MCAD tools are offering all kind of exports: STEP, IGS and a lot more; I would prefer PARASOLID then generic MCAD format. Bonus, 3D MCAD propose generally the 3D PDF export.

SketchUp is kind apart:
- today, allmost all 3d components are available in the specific SKP file format
- if not, STEP --> FreeCAD (STEP to STL) --> Blender (STL to COLLADA) --> SketchUp (COLLADA to SKP): if expert and small data size goes fast
- specific ulp in EAGLE for export
- specific tool in SketchUp
- restricted export ability to use with 3D MCAD tools (VRML should go)
- functional 3D PDF is option to buy
- very big files to handle
- but very simple to learn (care about units) and good for 3D printing

Ive proposed in the past a short tutorial for ECAD EAGLE to MCAD systems like FreeCAD and SketchUp but nobody was interested.

Today, full PCB check is possible (after successfull simulation): ERC, DRC and mechanically, with big components library, virtually faster then soldering iron heats.

Up to you, (with @AKSA permission? Im carefully) for GB!

Is that $9EUR each when ordering 30?

Hi X,

yes, 9EUR for 30.

Dimensions in *PCB.PDF documents.

JP,
The prices you are getting from your supplier is much less than what PCBway is charging. They wanted $130 for 10 motherboards including shipping. Thanks for giving us a lower cost vendor for PCBs. Although maybe would be less with 30 boards.

Hi X,

Sorry multi-cb ships only to Europe.

PCBWay: single pieces batch of 10, 2 layer, 1oz Cu, HASL lead free, 1.6mm, normal FR4 to USA (3-5days) = 98$ (Germany = 102$ including shipping).

Its not a panel.

Send fab datas for quotation?

JP

I actually sent Gerbers for quote - this is definitely an item for GB as cost for one person to foot for a preamp is too high. It was $98 but $35 for DHL on top of that.
