ECAD Part Wizard


Save time on your design with the new ECAD Part Wizard from SamacSys.

ECAD Part Wizard (EPW) gives you access to a wide range of high-quality, ready-to-use electronic CAD models, giving you the advantages of rapid design-in and fewer PCB errors resulting in a shorter time-to-market for your latest product design. 


Why should I use ECAD Part Wizard?

This great new tool gives you:

  • Complete control of symbol fracturing, including the number of fractures to be created and the ability to preview them instantly
  • User control over symbol pin positions (left, right, top, bottom) and pin order for each fracture
  • Layout footprints that are IPC compliant and include the nominal, least and maximum variants
  • Import of selected parametric data for your components
  • Export in to popular ECAD tool formats including Mentor Graphics, Altium, Zuken, Cadence and DesignSpark PCB
  • Ability to request creation of a specific model

And it’s all completely FREE!

Using ECAD Part Wizard is simple:

1. Download and install the EPW tool (you will need MS Excel 2007 or higher)

2. Search and download your component (if it’s not there simply request it within the tool and we will add it for you)




  3.  Fracture the symbol (if required)

 4.  Export the symbol & footprint to your preferred ECAD tool (we recommend using DesignSpark PCB but the choice is yours)

How do I request a part that is not available in the library?

Requesting a new part couldn’t be simpler, just select the button and enter the details and we shall create it for you.

@focusrsh using the download link on the URL for the Library Loader download in our tests results in a 396KB zip file containing the msi and Readme link which I just confirmed.
Support have also confirmed that the issue has not been reported previously, however please contact them providing the downloaded file and any other details to resolve your reported issue.

@bodnandi, please also send as much information as possible and support will work to resolve your ECAD issue.

NOTE. For the fastest possible solution to any issues please submit a request to support with full details and screen captures illustrating your experience.

Does anyone at DesignSpark bother to test if their programs work or even run?! The advise was to go to and download the Library Loader. What downloads is a 488 byte file named It is NOT a zip file and can't be opened. Jeez, what a steaming load of cr...garbage... this software is.


March 23, 2017 11:02

Hi I get an error when trying to export to pads. It says: Microsoft Visual Basic; Run-time error '429': ActiveX component can't create object - any help, please? Please see png attached as well.


February 20, 2017 10:49

Once again I've got the same problem everyone else has, has anyone found a solution? I am running the official 8.0 version of ds, so I'm sure its not that.
Also how do I export a component from here I hit the ECAD button and after clicking design spark it won't let me go any further


February 20, 2017 10:47

Same problem here, DesignSpark 8.0 & Library Loader not connecting.
My system is Windows 7 ultimate 64 bit.
Is it because I am running as a user and don't have relevant permissions to save data etc?
I need a solution to this please!


February 20, 2017 10:46

Reminder for users who do not like to use Excel for requesting symbols/footprints – please try our new solution ‘PCB Part library’ available already from ‘Our Software’ website:
Users who experienced problem with DSPCB - ‘PCB Part library’ collaboration - please reinstall DSPCB beta version to available already official 8.0.
If there is still a problem – please raise the ticket in our support page.
I wish you successfully accomplished designs – sped up by our new free symbols/footprints solution!


February 20, 2017 10:46

Same problem here, DesignSpark 8.0 & Library Loader not connecting.
My system is Windows 7 ultimate 64 bit.
Also I have Eagle 7 installed and the connection with Library loader is Fine.


February 7, 2017 13:18

I have identical issues as Jed-UK2 after installing Designspark 8.0 & Library Loader 2.02. My HP Laptop is also running Win10 and giving the same error messages as Jed-UK2. Are we missing out on any basic setup process after installation?


February 7, 2017 11:27

I've installed Designspark 8.0 & Library Loader 2.02, and I get the same problem as zhivko. If I launch Library loader first and then press 'Settings' Designspark launches OK but library loader then throws an error "Unable to launch/connect to DesignSpark PCB" please check installation, and try again.". The PC is running Win10, hard re-boots don't make any difference. Operating System is on an SSD, application software is on another drive, paths were edited to suit on install. Any suggestions? I abandoned DS 6.0 because of library issues, I'm trying to give DS 8.0 a decent chance before I uninstall it in frustration......


February 7, 2017 13:17

Can you make it work with Desinspark PCB 8 beta? On Settings and 8Beta installed I get "Unable to launch/connect to DesignSpark PCB" please check installation, and try again." error

Hi Everyone,

We have listened to your feedback and we're pleased to say that you can access our high quality Schematic Symbols and PCB Footprints without MS Excel.

You can get started here:

We support all the leading ECAD formats including Eagle, Altium, Zuken, Mentor Graphics, Cadence and more.

EPW is designed to help engineers quickly fracture a schematic symbol into smaller blocks when space on a sheet is a limiting factor, it is still a fantastic solution for this challenge. For those that just want fast, free access to libraries the link above is for you :-)

I can't get it to work with Excel for Mac.

I wish they'd just give us Eagle Libraries. Eagle works on everything.

How do I install this download ?. It seems to be a zip file with a pdf and a couple of .ex_ files. These look like they're compressed files, but they dont uncompress properly.


December 23, 2016 07:23

Quite useless to me as it requires MS Excel. I use OpenOffice and have no intention of buying Microsoft's overpriced products simply to use DesignSpark I'll find something else.


December 20, 2016 16:55

I have MSOffice 2013 32bit and doesn't start


November 14, 2016 12:18

RAJensen - Please see comment on Nov 2nd from - wgiergus


November 14, 2016 10:32

Completly useless if you have OpenOffice4.1.2


November 11, 2016 15:49

pcbjohn34 have you tried Library Loader? It is by far the best thing I have used. Watch this vid: you can download the models even from technical references on the RS website.


November 14, 2016 10:31

While this is a step in the right direction, it is nowhere near as easy to use as other tools like SnapEDA ( or PCB Libraries ( Also, is it only for Windows?


November 2, 2016 11:06

Thank you wgiergus. I will keep checking back.


November 2, 2016 11:06

We understand that some customers would prefer to work with libraries that do not require the use of Excel. We have recognised this and developed a solution that will launch within the next 2 months. We will of course keep you updated with these developments.


October 24, 2016 09:35

Funny that - I was just about to ask the same question. I use OpenOffice Calc for sreadsheets


October 24, 2016 09:35

Am I forced to use MS Office?
