Description

ASM 501 is a low cost but powerful DXF to Gerber translator intended to aid those who want to use AutoCAD (or other mechanical drafting programs) and need to create Gerber data for photoplotting.

Simple menus take you step by step through the translation process. Special functions help you assign blocks to flashes and set up draw apertures from polyline widths automatically.

Our powerful Gerber viewer, GBRVU, displays up to 48 layers simultaneously and lets you quickly verify your Gerber data before submitting your plot job.

ASM 501 outputs RS274X with embedded apertures which is supported by all modern photoplotters.

  • Menu Driven User Interface

    ASM 501/W is easy to use - the main button menu takes you step by step through the procedures to create Gerber data. Click each button and a dialog box opens. Fill in the settings (or accept the default settings) and move on to the next button.


    The main menu (control dialog) takes the user through each step required to produce Gerber output from the DXF file.

    Configuring the Translator

    The user can configure ASM 501's behavior quickly and easily. ASM 501 remembers your settings in the .ini file so that after you have used the program once, you don't need to re-enter settings that never change.

    Configuring the Gerber Output

    ASM 501W enables the user to control the RS274X output units, the precision format and the data mode as needed for your particular photoplotter.

    Defining Apertures

    In order to have a Gerber file you must define the apertures that the program will use. ASM 501 has an easy to use aperture menu.

    Special function buttons include:

  • Autoflash - automatically searpches the DXF file for blocks and inserts each name in the aperture list. You then need only define the size and shape of the flash that the block represents.
  • AutoDraw - automatically searches the DXF file and finds all polyline widths. It then creates an aperture with the equivalent diameter to each unique polyline width.
  • The aperture dialog window


    Circles & Donuts to Flashes

    Some designers draw circuit pads using circles or donuts. ASM 501 can convert circles and donuts to flashes. It does this by scanning the file when you click on the Flash Circles button. It maps each unique circle diameter and donut size to a block name which can then be placed in the aperture list. The Flash Circles menu gives the designer full control of which circle and donut sizes are flashed.

    Selecting Layers to Translate

    The Layer Select menu defines which layers to translate. You can control translation parameters layer by layer. Each DXF layer generates a corresponding Gerber file. You also can rename the Gerber output file if needed.
