What is vpm.sh?

The file "vpm.sh" (viewport mosaic) is bash script used to generate python ezdfx code "code.py". The "ci.txt" is an initial code used to construct "code.py". Final file "mosaic.dxf" is generated automatically by python "code.py" and contains a DXF2000 file with all the paperspaces and viewports configured. Of course, you can also generate all the paper spaces and view ports manually, but when the matrix to be represented is large, there is a lot of work. This script does the work in seconds!

Use:

Run the bash script like:

./vpm.sh a b nc nr m1 m2 m3 m4

Where:
a= X-size of the paper (mm)
b= Y-size of the paper (mm)
nc= number of columns
nr= numer of rows (maximal allowed number rc x nr is 256)
m1= paper margin top (mm)
m2= paper margin right (mm)
m3= paper margin bottom (mm)
m4= paper margin left (mm)

Example:

./vpm.sh 210 297 10 8 0 0 0 0

Generates a matrix of 10x8 paper spaces size A4 portrait with internal viewport 0 mm margins.

Copy the contents of your print.dxf drawing into the empty "mosaic.dxf" file and display the paperspaces result. The next step is to automatically publish all paper spaces, using a PDF printer with the correct paper margins (.pc3 file) and the appropriate color style table (.ctb file). And that’s not always easy. You need some CAD delineation knowledge.

Notes:

1) Be sure you have installed in your GNU/Linux or UNIX compatible computer al least:
bash
python3.6
ezdfx

2) Run bash script:
./vpm.sh 210 297 10 8 0 0 0 0

3) Sometimes, bash, python, ezdxf may give some dependency issues... You need to make sure everything is working on your system. Otherwise, you can simply use some of the available preconfigured dxf files.

Ready to use dxf mosaics:

dxf template	Paper	X-size	Y-size	columns	rows	X-size	X-size	Sheets
		mm	mm			m	m
A4-20x12.dxf	A4	210	297	20	12	4,2	3,564	240
A4-18x14.dxf	A4	210	297	18	14	3,78	4,158	252
A4-14x14.dxf	A4	210	297	14	14	2,94	4,158	196
A4-10x10.dxf	A4	210	297	10	10	2,1	2,97	100
A4-10x5.dxf	A4	210	297	10	5	2,1	1,485	50
A3-28x9.dxf	A3	297	420	28	9	8,316	3,78	252
A3-25x10.dxf	A3	297	420	25	10	7,425	4,2	250
A3-20x10.dxf	A3	297	420	20	10	5,94	4,2	200
A3-10x10.dxf	A3	297	420	10	10	2,97	4,2	100
A3-5x5.dxf	A3	297	420	5	5	1,485	2,1	25

All viewport margins set to 0.0, then set same values in your .pc3 file.

Have fun!
