Create PCBReader object with specified Gerber files and drill files

Since R2021b

Syntax

P = gerberRead(T)

P = gerberRead([],B)

P = gerberRead(T,B)

P = gerberRead(T,B,D)

Description

P = gerberRead(T) creates a PCBReader object with the top layer Gerber file specified in T.

Note

The PCBReader object reads RS-274X Gerber files. It does not support RS-274D Gerber files.

P = gerberRead([],B) creates a PCBReader object with the bottom layer Gerber file specified in B.

P = gerberRead(T,B) creates a PCBReader object with the specified top and bottom layer Gerber file names.

P = gerberRead(T,B,D) creates a PCBReader object with the specified top and bottom layer Gerber files and the drill file specified in D .

Examples

Import and View Top Layer Gerber File

Use the gerberRead function to import a top layer Gerber file.

P = gerberRead('interdigital_Capacitor.gtl');

Extract the metal layer from the file using the shapes function.

s = shapes(P);

View the top metal layer.

Input Arguments

T — Top layer Gerber file

Top layer Gerber file, specified as a character vector or string scalar. The file must be saved as a GTL file.

Example: gerberRead('Filetop.gtl');

B — Bottom layer Gerber file

string scalar | character vector

Bottom layer Gerber file, specified as a character vector or string scalar. The file must be saved as a GBL file.

Example: gerberRead([],'FileBottom.gbl');

D — Drill file

string scalar | character vector

Drill file, specified a character vector or string scalar. You can specify either a DRL or a TXT file.

Example: gerberRead('Filetop.gtl','FileBottom.gbl','FileDrill.txt');

Output Arguments

P — Files read

PCBReader object

Gerber and drill files read, returned as a PCBReader object.
