Hallo Guys......both personal opinions and statements are representing individual needs and preferences.
If somebody wants to make handdrawings for his models - fine
If somebody wants to use CAD, because he is able to do it and for his needs necessary - also fine.
My personal opinion and two cents:
30 years ago everybody made draughts by hand, like 200 years ago, In the meantime the time changed and drawings, I am civil engineer, so I know best related to my profession, drawings without CAD are impossible anymore. The big advantage is the replication and smal adjustments with one mouseclick, and very important the error-check of all elements, due to the fact, that all elements are related in one model and the 2D drawings printed are only excerpts out of this 3-dimensional model........so if your model works - no errors any more in your 2D-print out.
Unfortunately I missed the train of CAD learning in my profession, I had every time collegeus who know how to work with it, so there was also no need in my business, that I have to know how to handle CAD......now I am angry about myself, but I did not recognize in time, that this could also help in our hobby.
I am collecting drawing sets, especially from ancre (Boudriot, Berti, Delacroix etc.) people which new how to draw a plan, in the past by hand (like Boudriot) and nowadays by CAD (like Delacroix), so also in the hobby I have somebody who is delivering me the drawings.......but I can not (in moment) produce my own drawings (remark: I like 1:48 17th and 18th century, so no miniatures).
Nowadays with the upcoming technical possibilities of 3D-Milling, laser-cutting, 3D printing etc. I would give the left hand of my mother in law, if I would know how to work with a quality CAD-software - I am jealous, when I see what some guys here are able to do........
In principle I am very happy, that new technologies are coming up and also getting reasonably priced, so that the "normal" modeler can use it and make his models better. Remember brass photo etching! 30 years ago, plastic kits were standard and it was realy hard to optimize them......the market produced than these superdetailing kits (partly for high price) and modelers could superdetail there small 1:350 ship models.......in the meantime some modelers are producing by themself these photoetching parts.
If I see a computer carved figurehead or decoration, I am sometimes speachless how good they are already (and in 5 more years much much better I guess), nevertheless if I know, that a beautifull carved decoration is handmade - this is off course in my opinion the high-class of modeling.
But I am very happy, that much more modelers can produce much better models with new offered technologies. And this is making our hobby interesting for much more newbies, they have much more possibilities than in the past. And kit-producer have to revise their business models, otherwise they will loose the contact to the modelers and will not sell their old-fashioned kits. Because of this, some chinese manufacturer are dangerous for the "old" manufacturers. Designed with a 3D model, accurate and also in the meantime high quality timber........Without 3D-design such a kit-model like my La Salamandre would be not possible, and this 3D-modeling and transfering to laser-cuts was not copied by the chinese! No! This is done by themself.
Sorry, post got longer and longer........this was not only 2 cents....minimum 20 cents
