Best export from TopoDroid

[raz...@gmail.com]

Hello... Is there any way to export TopoDroid Sketches at a fixed scale? I saw that resolution setting at *.png File is not workin. I have exported at different settings of the resolution (1, 2, 3 ,4, 5) but all the images seems to be exported at 1m = 125 px...

TopoDroid Version 5.1.61

Thank you!

If the size of the memory allows, it can be exported to png in different sizes.

I have a galaxy note 4... i don't think is limited in memory...

What are the settings for example to export at 1:100 fixed scale (1 meter in the field - i cm in the sketch)? Is that any way to do this in TopoDroid? What resolution setting have to use? Or, what is the best way to do this?

Thank you!

the best way is to export as therion file.

Export the sketch as therion file... Seems to work, i opened it in csurvey and the scale is correct....

But how to use it after in illustrator as a base?

And... I need also the centerline and splays...

if you are illustrator, why don't you use svg export ?

I didin't saw any control in svg export also? What scale is exported by default?

So... What I understand, is that in this moment exporting at a fixed scale is working only to Therion format?

Illustrator can handle DXF, SVG and PDF.

I know what Illustrator can handle. Maybe I am not understood. My question was if it is possible to handle the exact scale for export in some format to use after in Illustrator with no scaling there.

I saw that for export in Therion (th2) you can set the exact scale (1:100) for example. But for the other formats, there is no such option.

This was my question...

Thank you!

DXF, SHP always 1:1, 1 drawing unit = 1m.

TopoDroid DXF export:

DXF 1 unit = 1m

Illustrator DXF import:

(https://community.adobe.com/t5/illustrator-discussions/how-do-i-import-dxf-files-into-ai/td-p/8101773)

Artwork Scale - Original Size - Scale: 1 Unit(s) = 1 Millimeters -> 1mm=1m = 1:1000

TopoDroid DXF export:

DXF 1 unit = 1m

Inkscape 1.2 DXF open:

DXF Input - Manual scale - Manual scale factor: 1.0 -> 1mm=1m = 1:1000

Use "Overview" from sketch page and then paste together screen captures. Definitely a work around to several problems.

BTW, I always rescale my SVG exports with a line plot generated by different software.

Therion export scale is actually xtherion scale, not the cave map scale,

which is set in the therion export command

SVG export scale is 1:100, as stated in the user manual.

this scale is a fixed setting.

it could be made an option.

what would be the usefulness of selecting a different scale for SVG ?

which export scales should be allowed ?

a finite number or a finite range ?

in either case which and why ?

Actually the svg export scale is 1:66.7 in what I did until now.

I have to scale the svg with 150% after is is placed in Illustrator to be 1:100, that is what I found...

It wil be good to have the option to export 1:20 /1:50 / 1:100 / 1:200 / 1:500 because is better to not make any other modification of the sketch after, just to show on/off different layers...

Thank you!

[Marco Corvi]

is the scale 1:66.7 also with inkscape ?

In Inkscape / with normal opening - The grid is 1 m = 5 mm

That means that the scale is 1:200 (1 cm : 2 m).

I will try to see if all the exports are the same.

Adobe Illustrator 72ppi, Inkscape 96ppi default.

this means there is the need for a new setting to choose the target SVG program

 This is from illustrator, even if it was imported after was opened and saved in INKSCAPE.

Some settings force the import at this scale... 1 m (TopoDroid Grid) = 6.67 mm

This means the scale is 1:150  - 1 cm in the paper is 1,5 m in the field (so this *.svg images have to be scaled at 150% to be 1:100).

I was mistaken in the first e-mail about the export scale (not paid attention so is not 1:66,7).

thanks,

now this makes sense.

as it is now illustrator is 4/3 times inkscape, because 96 point used for export are 4/3 of the 72 points default of illustrator.

i added a setting to choose the target program, and adjust the export points accordingly.
