DesignSpark PCB provides a 'Manufacturing Plots' feature to allow you to produce Gerber files and use any board manufacturer you wish. Before producing the Gerber files ensure you have completed all the design checks of your PCB layout to ensure you do not have errors or unexpected cost penalties from selecting nonstandard track widths or spacing or other premium features.

Definition and Necessity of Gerber Files Initially developed by a company with the name of Gerber, Gerber format currently refers to a widely accepted standard PCB industry software sticks to, capable of describing circumstances of board images such as conductor layers, soldermask layers, legend layers.
The most widely used file format for PCB manufacturing is called Gerber. When manufacturers request “Gerbers” or “Gerber files,” they basically look for ASCII files that contain Gerber-formatted data. These are actually “CNC” files. They drive the photoplotter to create the film that is used to expose each conductor layer in the board.

RS-274X includes many high level commands and controls that let the creator of the Gerber data specify the PCB (photoplot) very precisely. The file contains all critical information.
RS274X is an extension to standard RS-274D (commonly known as Gerber) that includes:
Pcb Artist Gerber Output Kit
Embedded format, unit and data information
Embedded apertures
Custom aperture definitions
Film control statements
Multiple layers embedded in a single file
Special polygon definitions
The RS-274X specification was originally developed by Gerber Systems.
Determine if your Gerber files are in RS-274X format or RS-274D format.
Open a Gerber file with a text file editor like ( Notepad, Wordpad,… ) If the files are in RS-274X format the aperture definitions will be embedded at the beginning of your file. There will also be a header which shows the coordinate format and other options you have selected when generating the Gerber output.
Example: %FSLAX24Y24*% this means : Format Statement Leading Zeros Suppression, Absolute Coordinates format=2.4.
The syntax is defined in the following image:
where:
L = leading zeros omitted T = trailing zeros omitted D = explicit decimal point ( meaning that no zeros are omitted)
A = absolute coordinate mode I = incremental coordinate mode
Nn = sequence number, where n is number of digits ( rarely used)
Gn = preparatory function code ( rarely used)
Xa = format of input data ( 5.5 is max)
Yb = format of input data
Zb = format of input data ( Z is rarely, if ever seen)
AD – aperture description parameter D{code} d-code to which this aperture is assigned (10-999) C tells 274X this is a circle macro R tells 274X this is a rectangle macro $1 value (inches or mm) of the outside diameter $2 optional, if present defines the diameter of the hole $3 optional, if present the $2 and $3 represent the size of a rectangular hole.
If you see the aperture macros present in your files then you definitely have files in RS-274X format.
