Here's a Lisp routine to make a spiral. If you have a newer version of AutoCad (2008-2009) the capability is built in - look for "Spiral" or "Helix" in AutoCad help
The snap is toggled with SHIFT+E (hold shift and hit "E"). The status will be shown in the status bar at the bottom of the screen. In the newer versions of Altium, there are three settings - Off, snap on current layer, and snap on any layer from current layer.
Re: Teaching of pcb design
Hi Kishor Jadhav,
It looks like there might be a language problem here. Where did you read, or see, about "the Teaching"?
If we understood the context, we might be able to answer your question.

First, hit the "Clear" button at the lower right corner of your PCB Editor workspace to clear any masks that might be set. Then try unchecking the box in "Preferences>>PCB Editor>>General>>Protect Locked Objects".
If that doesn't do it, look to see if the box is checked for "Preferences>>PCB...
To reduce the current from 12amps (1440watts) to 5amps (600watts), you either need to use a transformer to reduce the voltage coming from the wall socket from 120vac to 50vac, or you need to increase the resistance from the design value of approximately 10 Ohms to 24 Ohms.

cst to gerber
Hi thephuong07,
Attached is the Gerber file for your spiral. I imported your DXF file to CAM350, poured a polygon into the empty spiral, and exported the result to a Gerber layer.
The whole process took less than 2 minutes.
Since your DXF file didn't specify units or...
If you find a friend with one of the newer versions of Altium Designer, they can directly import PADS files and save them to Protel99SE format.
If you would like, I would be happy to help you out. Just zip or RAR a copy of the file to protect it and PM it to me. I should be able to get a...
how open pcb file
Your file is most likely a PADS binary PCB file. They put the ASCII stuff toward the end of the file.
If you want, you can zip or rar the file and PM it to me, and I can probably get it into a format you can open in Altium Designer.
Re: Altium FPGA design
The JTAG interface in your Examples folder is a parallel port interface/adapter that allows you to connect between the parallel port on your computer and the JTAG connector on your third-party hardware.
The USB adapter is an interface between the USB port on your...

Wouldn't you be able to accomplish what you need by processing the netlist? Trying to read that information directly from the schematic would be far more difficult than parsing a netlist.
convert pcad gerber file
If you RAR or Zip your PCAD file, and PM it to me, I'd be happy to try and convert it to PDIF for you as a favor for a fellow designer. I might even be able to convert it to Allegro 16.
how to use via in altium
To place a via manually, use the shortcut PV (Place>Via). To place a via while routing, just change layers - your default via defined by your design rules will be placed when the track changes layers.
To set up the via sizes, follow the directions in the post above...
