Techdraw - Dimensioning at contour curves with asymmetric radii
Hi all,
when drawing asymmetrical contour radii I encountered the following problem, for the dimensioning of the radius sections usually tangents are needed. I could not find an automatic function for this in FC. Unfortunately, I could only help myself by drawing them in a separate sketch "underneath".
.

.
My question is now:
Could an automatic function be programmed for this, which can be switched on and off?

Re: Techdraw - Dimensioning at contour curves with asymmetric radii
Please elaborate. I don't understand what you mean by "asymmetric radii" nor do I see a TechDraw page in your file, which could have helped to better understand.
A Sketcher Lecture with in-depth information is available in English, auf Deutsch, en français, en español.
Re: Techdraw - Dimensioning at contour curves with asymmetric radii
I added the TD page in my file.
What I mean is e.g. :
You have a symmetric contour radius:
R20 = x20 y20
An unsymmetric contour radius:
R20 = x17, y23
For dimensioning the unsymmetric radii, TD cannot supply any intersection points.
They can only be very elaborately inserted by cosmetic vertex (points) and are usually inaccurate.

Do you know Sketcher_ConstrainTangent ?
I don't understand unsymmetric contour radius.
A fillet has ONE radius.
For TWO radius, you need TWO arcs :

I'm talking about ONE radius!

Re: Techdraw - Dimensioning at contour curves with asymmetric radii
what is the meaning of : R20 = x17, y23 ?
Re: Techdraw - Dimensioning at contour curves with asymmetric radii
The dimensioning of the radius in x- respectively y-direction.
Re: Techdraw - Dimensioning at contour curves with asymmetric radii
See:
Just said, that have nothing to do with symmetry. The term you search is intersecting points.
Depends, i know many controls of CNC, they need only the intersection points and fillet radius. Besides that the intersecting points can be need for any other things in drawings and documentations.

You need to use an ellipse's arc.
