Hi @sjoerdg
Wow! You’re doing great 
I’m battling the war of putting pleats into a blouse that will also serve as darts. For something that sounds so simple, my pea-brain is really battling

Good evening Mr Soerj. When I want to use your pattern an error message appears, a copy of which appears. What should I do ? . Note that I use Valentina software. Yours truly. Erreur draw.docx (23,8 Ko)

If the pattern was saved in Seamly2D with a version greater than 0.6.3, it will no longer work in Valentina (and vice versa). I suggest try using Seamly2D.

I followed your valuable advice to the letter. But Seamly does not have access to my “Desktop” then “Taking measurements” where the ZPattern file is located. What should I do. Thank you for your understanding. Please find attached a screenshot. Thank you for your understanding. Seamly echec.docx (119,1 Ko)

Try clicking on My Computer and then Desktop on the left section of the screenshot that you sent.

You have to setup the file paths in the Application Preferences->Paths. I’d attach a screencap, but I dont have internet access with my laptop at the moment.

Thank you for this explanation to the first one who asked about this curve issue- this actually is my first quick study into this very specific and necessary quest concerning “understanding” the way the curve will behave. i have to admit that this DOES make a little more or a little less than half-way sense… not letting this comment sink in TOO far down i ALSO state here that the plan is too FULLY “UNDERSTAND” this debatable and questionable worthwhile AND time-consuming mathematical algorithm about how to precisely and correctly and artistically but first of all, ARTISTICALLY, and then, (“approximate” mathematical symbol) correctly, manipulate a curved line using point a through point a6- but with that said it is a worthwhile endeavor i continue to engage in, FREE, and this blog is so super zuper COOL, and well, THANK you.(i WAS simply looking for how to use a “FRENCH CURVE”- i will look for this next, this is MORE than good enough for now, but i am making my own clothing company from scratch no prior knowledge no skill just my heart just my soul just my spirit my mind no money and a thank you.)- thanks Douglas.

The French Curve is just a ruler that helps you to draw curves when working by hand. Professional pattern makers learn (with experience) to draft these curves by hand - without the need for extra rulers.
When drawing curves, one needs to bare in mind that if the start and end angles are not at a 90° or 180° angle to a seam, it will result in a peak or valley once the pattern pieces are sewn together. With this in mind, always check where you are drafting the curve and use the connecting edge as the formula for the curve handle, adding or subtracting the 90/180° as needed.
The length of the curve handle depends on the length of the area that the curve needs to travel before changing direction to form the curve. Normally, 2 sides lines are drafted before one drafts the curve, so I use the 2 side lines divided by 2 for the respective lengths of the curve handles.
I hope this sheds some light (theory) on the matter.
I do suggest that you download and install tomorrow’s weekly update It has an amazing change to simplify drafting curves, which you may read about in this topic: Auto-Smooth & Force Length (Code available, looking for dev help)
I’m wishing you all the best with your clothing company venture.
