Bug with _-export

Rhino Rhino for Windows
1

Hi,

just noticed that when I try to use the command _-export (as a pdf) on a dot line, it changes the scale of the dot line (this change depends on the position of the camera). The command _export works fine though.

Is there a solution to make it work? I use this command in a Python script because I have a lot of drawings to export as pdf, and would be good if I don’t have to do it manually. I use the command _-export instead of _export to change the selected windows in the option “ViewportArea=Windows” so using _export is not a solution… Thank you for your help.

Cheers,

JB

Hi JB- see if in _-Export, once the pdf file is specified, you can set the parameters for
SetUp > ObjectSizes > Linetypes, within the -Export command

-Pascal

Hey Pascal thank for the reply. I use ‘UseDisplay’ for the Linetype.

If I use ‘UsePatternDefinition’, I get a random dot spacing with my dot lines that I don’t know how to set up.

Hi JB- It seems to work here - can you post a file with curves that do not work right? Maybe I am not looking at the right thing.

thanks,
Pascal

Hey Pascal,

Here’s the file.

Hi JB- I see that, thanks - it looks like running -Export also resets the linetype scale if it has been set before, do you see that?

Yes, I see that when I set up Linetype=UseDisplay.

But when I set up Linetype=UsePatternDefinition, the scale changes as well, but differently: the scale after using -export depends on the view. For example, I setLinetypeScale = 100. After using -export, I get setLinetypeScale = 69.18. Then I zoom in and I setLinetypeScale = 100, I will get setLinetypeScale<69.18 after using -export.

So in a nutsheel, when you zoom in, the scale becomes smaller, when you zoom out, the scale becomes larger
