 * select the projection view -> properties tab -> Data -> “Projection” record section -> Source click on the button with the three dots and directly add the “base-sketchTD” or the layer that contains it.
 * It should be noted that the "base-sketchTD" must be positioned on the highest face of the model / object, otherwise it will be hidden and will be invisible in TechDraw.

The sections obtained from the views do not seem to have this possibility. Whenever it is necessary to create precise cosmetic points suitable for dimensioning (e.g. tangency points), they can be generated:
 * in "Sketcher" through construction lines and inserting circles with infinitesimal diameter / radius (0.00001) in the ends, these will be seen by TechDraw as points / vertices suitable for dimensioning;
 * in Draft with the same method to be inserted in the relevant layer or folder-grouping;
 * once the "base-sketchTD" has been modified or the Draft object added in the layer or grouping folder, TechDraw will automatically update the view, if this does not happen, update manually with the appropriate command.

To insert section fills or patterns: pay attention to the lines created on the faces that intersect two or more edges, they are seen by TechDraw as separating elements of the face that affect the creation of the fills or patterns. This occurs e.g. when creating the outer lines that define the thread of a hole, this line will prevent the fill or pattern from extending further preventing it from arriving on the one that defines the pre-drill hole. In this case it is better to create cosmetic points through construction lines by inserting circles of infinitesimal radius in the vertices that will be seen by TechDraw as cosmetic points and then join them in TechDraw with create cosmetic line by two points. All lines and / or paths (including cosmetic ones) that are displayed in the views can be edited in the formatting through TechDraw's “Cange Apparence of selected Lines” command. To create specific continuous sections on different axes or planes, I used the “WorkFeatureDev” workbench which allows you to create “solid” planes, with a thickness of “0”, by selecting three vertices. These planes can be joined through a common or overlapping edge using the Boolean functions of the “Part” workbench and subsequently used for slicing / sectioning the solid model through the “Slice apart” command of the same workbench. The faces of the cut objects can be suitably exploited for the creation, with the “Facebinder” function, the “base-sketchTD”s to produce specific section views in TechDraw and therefore to be able to dimension and detail them. I believe I have made public every "trick" (or rather system) experimented to be able to use more specific tools (not provided for TechDraw) and create high quality professional technical drawings without any limits, making the TechDraw workbench more efficient and adaptable to any need, in all likelihood on par (if not more flexible and powerful) than commercial peers. It should be said, which is not negligible, that with this system it is possible to create entire 2D files and quote them with TechDraw in the same way as "LibreCad" or "Autocad LT" or other two-dimensional cads. I hope I was clear enough (translation permitting) in explaining the procedure ("trick / system") that I believe to be "easier to do than to say", as it is all about being able to enter 2D drawings into the views of TDs created with "Draft" and / or with "Sketcher" simply by selecting them from the structure and creating a view in TD with the appropriate command "create a view"; but I thought of doing something pleasant and more technical by describing the procedure, certainly, in a "simplified" way to create a minimum of organized workflow. It is up to each of us, with imagination and inventiveness, to optimize it to the maximum to obtain the best result. I am attaching the files of some workflow examples of technical drawings (not feasible with TechDraw only) from which the images shown below were taken. In the hope of having been useful, good work and good experimentation!
