I am using Allegro 16.2. I want to import a .DXF file ( attached in this post).
Basically it is a package symbol layout with mechanical holes.
I am confused in setting the layer mapping.
Could anybody please go through this file and tell me what to be done to import this file so that no informations in it is missed.
The basics are you map a dxf layer to a layer (class/subclass) in Allegro. Here's a video showing an example. http://www.youtube.com/watch?v=wTegtW9bPCs
I down loaded and unpacked your dxf and was able to import it tp allegro with no issues. Here is how I did it :
1 - From the file menu select import dxf.
2 - When the dialog box opens click the browse button and select the dxf
3 - Select units : inches (we work in inches)
4 - check incremental addition
5 - click edit/view layers
6 - select the class and sub class you want. (I selected package geometry and assembly top)
7 - click ok, then import
In it came.
Here is the .cnv file that was created :
#This is the Layer Conversion File used for#importing DXF data into Allegro/APD.
#CLASS! SUBCLASS! DXF_LAYER!
PACKAGE GEOMETRY! ASSEMBLY_TOP! 0!
Hope this helps.
In reply to VincentS:
Thnaks a lot for your reply.
I am confused in step 6. What class and sub-class actually to be selected.
I am expecting that this .DXF file will create the package symbiol which is going to be used in the layout.
I did the way you did and I got something like the image attached in this post.
But pad foot-print and the holes are NOT suitable for using in PCB layout.
In reply to RFStuff:
You can import to the class and sub class of your choice. If you are going to use this dxf as a model fot creating a footprint you can import it to Board Geometry Dimension. Once imported you can use it as a guide to place yout pads. Caution : make sure you follow the manufacturers dimensions. Even with the dxf you will still need to design the pad stacks.

I use the Mentor LP Wizard for footprint design.
Thanks a lot for your reply.
Currently I am using dimension of 1-mil grid spacing.
How can I know the manufacturer's dimensions from the given .DXFfile ?
You will need the datasheet for the part or the datasheet for the package. They are usually available online.
