Since long I wanted to create a Sketcher tutorial. Here is a first go, currently as a pdf, I would like to provide it as HTML and video as well.The following directives have guided me.
Nov 14, 2015 PhotoSketcher is a delightful mac app for effortlessly turning your digital photo into an artistic pencil sketch. Just drag and drop your photo on to PhotoSketcher window and see the magical result. Key features: Intelligent algorithm produces great result out of box, no painful tweaks needed.
The impression that proper sketching is often learned on the fly. In many tutorials Sketches are badly constrained. Several topics here in the forum show, that some users have to be taken by the hand for every single stepSo I started this and I am not sure wheter I pushed it over the top: The preliminary remarks took already 10 pages! So I better ask now if it is too detailed, before I'm going into the constraints - which is what I really wanted to talk about.Especially I would like to hear your comments on the following:- are there errors or improvement recommendations concerning the contents?- ist too detailed?- I put the Point as geometric element to the end because it is rather construction geometry. Should it be the first among the geometric elements?- should I add B-splines, ellipse and other conic sections?- when being in Sketcher, do we talk about '3D view'? I ask because it is rather 2D- the examples and exercises are not final yet, I am looking for easy to grasp models, preferably with some well known application; any proposals?- I am not sure about the position of the external references section.
Should I put it into the constraints section?- and of course I would like to get advice on spelling, grammar. The fact that I make many typos in my posts is sad enough. Chris,Looks like a great start!I won't get into any grammar or spelling at this time. Nothing serious, and nothing that needs immediate attention.The level of detail is very deep. So much, in fact, that I wonder who is the target audience? Absolute beginners or those who may not really understand the concept of constraints and solvers may want the detail. Those who may already have some grasp of these concepts and simply want an orientation to the FreeCAD way of designing may find it a bit too elementary.I wonder if a bit of arrangement would be useful.
For example, at some point just explain the geometries and their specific constraint types without the extra verbiage of examples.Perhaps the wiki should serve as the sole reference for that sort of thing, but I get the sense that the wiki is a bit difficult for many beginners.In any case this looks like an important resource, and you have already made a strong start.Gene.

Absolute beginners or those who may not really understand the concept of constraints and solvers may want the detail.That is a very good question and I have to confess, that this tutorial developed some previously unintended 'autonomy'. While writing I more and more had the feeling that the basics have to be mentioned. So the audience is absolute beginners on one side. They can simply go through the simple exercises and learn how to create sketches - hoping they will not develop bad habits.
I have seen many of those bad habits, so the tutorial might be useful for people with considerable experience as well, hoping that they can not only follow some advice, but rather understand why things are recommended.
