Unless you renamed the first sketch, it will be named 'Sketch' and it is the Sketch closest to the top in the tree view, unless you moved it. In the Part Design workbench we can only move the very first Sketch because everything else is built off of this first Sketch. If you're trying to map a sketch to a face, the origin of the face doesn't matter. Read the wiki, there is heaps of information there, some may be incomplete or out of date but it will answer the majority of your questions and probably even show you more useful things, that you hadn't thought to look for. There are usually many ways to achieve something with FreeCAD. Alignment.pick three or more points on two different solids then click align and FreeCAD will move the solid such that the points line up with the other point selected on the other solid. then either use in absolute mode or tick incremental.the tool can rotate (with a centre of rotation defined anywhere) can be moved any amount in any axis, or even a custom vectorД®dit menu.

Being able to hand over a printed paper drawing to a machinist would make this issue less important. Using sketches as 'drawings' is possible, but it has limitations, as outline above. The 'Transform' tool ( a very tricky tool) can rotate the part, but the input is with mouse, and a cut'n try deal, if the 'Transform' had a text-input in the DATA-placement-tab, and would not collapse, and provide numerical output while moving the object, it would be a little easier to see what you are doing. It would be nice if I could align the origin of a sketch to a point that makes sense, and not have the origin in the middle of the part, or some such. Making a sketch on a part, for making features, may pull in references outside the object. If i want to make a copy of a part, and mirror image it, I don't want to inherit the origin axis of the original part. Once I save the part (I wish auto-save was not grayed out) it is no longer a 'step' part, and some hidden properties are just an annoyance. stp parts, where I want to change their orientation and not be hindered by hidden links to offset from an origin, so that when I rotate the part, it rotates around its own axis, not the axis of some other part in the 3D space, that is not even visible in properties of the part. I very often create a rectangle shape the size I want the guides from the edge and then use with this on the right side to give me a marker to drag the guide line in.The reason for being able to set origin of each part, which I run into a lot in using various. Then from here I can quickly drag in any guides I'll need and then set them with the Guides Manager by just imputing the measurement I want. I set four guides around the edge for the design area artboard first, its quick to do with the Guides Manager. Use the Guides Manager (View Menu) to set all your guides. Just drag elements across from one artboard to the other. Then I create another artboard to the side for testing a dumping elements. Just create one artboard as the design area, the ruler will zero to the edge of the active artboard. Im still getting used to AD but I find that using artboards for the same purpose is better, along with Guides Manager (View Menu). The area outside the guides was for dumping elements or testing stuff before I dragged it over into my design space. I used this feature all the time in Corel, create a new file, drag a vertical and horizontal guide away from the edge of the page and then zero the ruler to the corner of the guides.
