Hello.
When I load my own parts in Illustrator into PCB View, the rectangle is one size larger than it should be.
I am having trouble understanding the cause of this problem.
I have the following settings for exporting SVG in Illustrator.
SVG1.2 Tiny
Responsive checked off
I have attached an image displayed in Illustrator, an image displayed in Fritzing, and a home-made SVG file.
Can you please tell me what is wrong with my home-made SVG file?
Yes I can tell you what is wrong: the dimensions are in px which will cause Fritzing to guess at what DPI (72DPI or 90DPI or the current 96DPI that Fritzing I don’t think recognizes) and uses that. It sometimes gets it wrong (this is displayed in Inkscape):
the dimensions need to be either in or mm to set real world coordinates. I haven’t seen a way in the Illustrator documents online to achieve that though. This post may provide some help:

I was not aware of DPI. I will keep it in mind in future productions.
I downloaded and tested Inkscape.
It was caused by the fact that the stroke is automatically set in Illustrator.
I will use Inkscape from now on. Thanks for answering a newbie’s question.
If you are new to making Fritizing parts then the tutorials I posted in another thread this morning will probably be of interest if you haven’t already seen them and we are always willing to help people make new parts.

Thank you! That will be useful advise for those running in to scale problems in Illustrator. I likely didn’t know what I was looking for in the documentation!
Peter
Thank you very much. I will study the tutorial carefully.
Yes, as noted, you need to specifically set the stroke weight [in Illustrator] to something ridiculously small—I usually set it to 0.01pt (because I work with points for stroke width—this is 0.004mm, but 0.01mm would probably be fine, no pun intended, too) so that it is effectively zero.
I see! That’s a great idea! Thank you!
