Well! that last flury of activity has been very rewarding, much of it was over my head ... (inspiring rather than depressing)
Over the w/e, I re-drew the cone from scratch and the hollow cone problem vanished. Thanks for all the advice I should have listen to earlier, ( trapeziums with gaps!)...
The fragility of my system STILL remains. there must be a pattern but objects vanish, commands fail to do the same thing ,..
I confess, I do experiment with procedures, in the past this has been a powerful learning method but re tracing a failed procedure may leave unrecorded errors, (user error)!!
Maybe the following text is verbose, it was an attempt at being thorough;
I believe a re-install is on the cards as a Christmas present.
Thanks for all of the help, I am now nearly ready to send this model for 3D printing, it only took 45 days, It would still take me several days to repeat it from scratch!
I still need help with a few ongoing problems that have been covered all ready, but not adequately'
1. Saving and recovering drawing board layouts.
1. 1. From the start, I needed to create a layout signicantly different from any of the options that appeard in Tools / Customize—›Options....themes
I saved a template I liked, but could NOT recover it.
However, on browsing avaiable templates my templates where there as *.XML files! Is that the file that should be loading?
If sO, first problem is how to access those files for applying when needed.
Right now I simple overwrite the CadCourse as my layout. Not very professional behaviour!
1.2 I have felt the need to re-install TCAD several times and this obviously looses any user made template.
It may be possible to save the my xml files externally and add them to the options after TCAD has been installed BUT I believe there may be a file somewhere which keeps a register of files and this would need to be edited as well., I hope that is clear
2. Colouring objects
When I was using TCAD 10 years ago, I found this task relativly simple, I used a brush, pallete and a material; I believe that there was a simple distinction between pen and brush
There was no reason to use levels and I do not recall the many ways that palettes appeared.
All in all it was far more simple and quick to learn.
I would like a DETAILED list of commands, including where they are found and detailed parameter passing protocols etc. OR a pointer to where this exits, e.g. a video
3. System instabilities
As mentioned above, I have reinstalled several times and will repeat that very soon
For example, right now I sometimes click a button or some such and the drawing or part of it vanishes. a redraw gets it all back, it looks like a system failure to me.
4 What constitutes a valuable reply to a request for help from the forum?
I feel I alluded to this in 2, above.. The vast majority of replies to my questions have been full of useful advice and helped a LOT.
But some replies assumed I am a competent, trained user, I think it may be assumed that I need to be told NOT just what command name is needed but whether it is a button, where it is found, the hierarch route from the standard menu etc...
Even some of the better online help videos assume existing knowlege, or go so fast that I am for ever stopping and back peddling.
Sorry its so long winded, but I hope it's clear...
