While working with TechDraw experienced problems:
1. Very long scaling time for multi detail projections - up to a minute or more.
2. Sometimes clicking to insert a projection returns an empty projection.
What does it depend on?
What is better:
-- to store all projections in the same file with whole model? (this is convenient but may the file break or become unusable?)
-- to extract each detail to a separate file and save each projection in it?
Wat is the purpose of each view?
In particular need to make a three projections tech-draw. What would be the optimal work-flow?
Hello "Smiling_user" a greeting to the whole community!
Here are the phases that should be observed very generally
(to limit job or file loss and be efficient and productive)
- realization of the prototype-assembly (it is the most confusing and heavy modeling because it includes all changes / cancellations and updates) here no technical drawing should be inserted;
Important advice: "as a general rule it is always better to proceed with files in progression (even in the naming) for each work session (even a few minutes, as the crash is always around the corner) and remember to save a lot, very often especially with large files "(which I always advise against creating)
- export of parts and sub-parts in single files (once defined in the prototype assembly);
- reassemble the parts / sub-parts (in FC with linked or imported "Assembly") in order to check if everything works well;
- proceed to the creation of the technical drawings of the reassembled assembly (views, sections, compilation of tables and computometric: references of the various parts, denomination, quantity, materials, technical notes: normative references, assembly references, references of commercial components and other specifications considered important for the purpose of realization) in sufficient quantity for the purpose (nothing should be left to chance!);
- for each part file proceed to the creation of the technical drawings for the specific construction (including the sub-parts or basic components) here also the specifications for any welds, tightening torques, tolerances etc must be entered; all technical drawings must contain every detail for correct construction;
- for the parts to be created / machined with cnc machines proceed with the creation of the specific files (* .stl -> Gcode with CadCam)
- proceed with the creation of the assembly technical drawings (parts, sub-parts and overall), here also the specifications for any welds, tightening torques, tolerances etc must be entered;
Naturally, we proceed hand in hand with the (not only structural) static and dynamic checks, etc. (before the final documents).
All these phases are valid both for the artisanal production of very small or single quantities, and for the mass production, to which many other works and studies that are outside your specific request must be inserted.
I hope I was clear concise and helpful (I apologize for my inaccurate English).
