Re: [kicad-users] Re: I need a footprint for a 5W wire-wound rectangular resistor...
I found out the basic steps by trial end error. If anyone has some tips - especially for getting proportions and scaling correct, then that would be good. Obtain wings3d from http://www.wings3d.com/ Learn how to use it from http://www.wings3d.com/doghouse.php and see what else it can do by looking up wings3d in youtube. When you are ready to create a 3d component, then make one using wings and concentrate only on the relative proportions. This is because Kicad's module editor links the 3D in and scales and rotates according to your needs. Therefore, a basic axial R component could be scaled differently for different wattage. Hint: A toroid can by streached and cut in half to make leads, while a cylinder or cubes make the basis of the component itself. Save the wings file. Then export it into VRML 2.0 format. This is what Kicad can read. Create your footprint in Kicad, use it in your PCB layout. Double-click on the PCB footprint while in PCB layout and then click the tab to set up 3d. Browse to the VRML 3d exported file. Find the right scaling and orientation to make the leads fit into the pads in the footprint. Update the library and your board. Test the 3D view. Learning curve: About 4 hours or so. On Saturday 27 October 2007 18:17:22 jeremy wrote: > Thanks. > > I've muddled through that. How do I make a 3D model and link it > to the footprint? >
Re: [kicad-users] Netlist
Hi Peter. You should run the EEchema Annotation before, for automatic numeration. Note that some resistor with value 120k has "R?" identification, after run this tool, the character "?" will be replaced by some sequential number. You can put manually a number in this resistor as well.

[kicad-users] Re: prototype PCBs
Ahh! I always wondered where Sparkfun Electronics got their PCBs made. There they are listed as a partner on the Gold Phoeonix PCB site. Sparkfun is a fair priced, hobbyist focused company. I'm encouraged by this association. > I use http://www.goldphoenixpcb.biz/ and so far so good. The ship > primarily to the US... but also to Europe. >
[kicad-users] Re: prototype PCBs
CustomPCB is now renamed Silver Circuits and their web site is worth a read for the information it conveys re the considerations when dealing with a board house. http://www.silvercircuits.com I can get a 3.9" x 6.3" board, single sided, from Olimex > for $35 including shipping, and this includes free panelization, which > is good for me since I usually stick lots of small boards together > onto one.

Thanks. I've muddled through that. How do I make a 3D model and link it to the footprint?

First find a datasheet for the resistor you are using. In your case download this from the YAGEO website at www.yageo.com. Using the dimensions contained in the datasheet you can then make the footprint. If you use another resistor because the yageo ones aren't available follow the same procedure. David.
