Macro Generator

Here’s an advanced point placement technique for MacroGen. I’m marking an armscye, and the instructions say:
Measure down from the Shoulder Point two-thirds of the distance from the
Shoulder Point to the top of the Side Seam and mark point A on the
Shoulder Width line…
The shoulder point and the side seam point are not on a vertical, so I
need to measure 2/3 of the Y component of the distance, NOT the
straight-line distance between them. There’s more than one way to do
this. I could add a rectangle point that does lie on a vertical line
with the shoulder point, then create a new measure and multiply that by
2/3. But there’s a way to do it using fewer intermediate steps, with
the ResizeXY point. Here’s how that looks:
The function arguments need some explaining. The formulas for “X
Factor” and “Y Factor” appear similar to what you see in other Point
dialog boxes, but with ResizeXY they are not distances but multipliers
for the given distance. The dialog above says to measure from the
shoulder point (Shldr) to the Side Seam point (SS); multiply the X
distance by 0 — that is, no measure value and no constant value–and
multiply the Y distance by 0.667 (that’s 2/3). Point A, then, is on a
vertical line with Shldr, 2/3 of the vertical distance from Shldr to a
horizontal line going through SS.
The written instructions then continue,
Measure three-quarters of an inch in from point A towards the Center Front line and mark point B.
That step will require a Coordinate point, which I won’t cover here
since it’s our most basic point function. So, I’ve reduced the process
of measuring out the armscye point from four or five steps to two. It’s
kind of a lot to keep in your head at first, but once you get used to
doing this it makes work go faster.

Hi Gary
Could you give a pic of the draft detail, please - it is easier for us not english tongues to follow a technical speech.

Heidi,
Would creating a video on this work as well as creating pictures? Either way I will create something without all the technical speak.

Yes, this would be fine. I love MacGen because I can "program" without knowing all that stuff.
thanks Gary

Hi Gary,
this is great. Oho. I looked now closer to the other features I never used because I did not know what to do with them. I see now, I can do seam allowance like I wnat them with the point offset in MacGen.You gave me some new toys.
Thank you.

Hi Heidi,
Glad to hear you have a new toy. How do you plan to do seam allowance with point offset? I woud like to see that.

Oh I have done an example. I load it up (if I'm able). It is just an rectangle. I must look if I can do it with curves. After Carneval! I'll have a lot to sew.

no I'm not able

Can you email it to me? Then I can take a look.

hi Gray,
here it is. I have not done curves - but I think they will work

Thanks! Curves will work but will look off in MacGen but should look good in Patternmaker.

Really interesting, thanks a lot ! It works very well on a curve.
Would there be a similar trick to obtain, not a fractional distance, but a fixed distance, on a curve ? For example, I have to divide or put notches on a quarter of a circle which represents the waist of a skirt, according to fixed distances. I have only found that I coult draft a circle so to obtain afterwards '2 arcs intersect', but it is so tedious !
I am sure it can be more simple, but I have not found the way ...
May someone please help me ?
Regards
Catherine

Hello Catherine,
I will work on this. I do not have an immediate solution that is straight forward. I may have to do something tricky. I will get back to you
