Re: LDCad 1.4b (twisted cables) - Roland Melkert - 2015-04-23

O wait I noticed I got the scale wrong from your pictures, those 180 twists are using way more the 4ldu length segments.

It seems the segments are merged while they shouldn't, this because it merges based on the path y direction angle (0 deg) and does not take into account the roll difference Smile

Thanks for noticing this Philo I'll make some improvements in one of the 1.5 versions.

In the mean time you can just disable merge by setting the skin's max merge to '1', like in the attached mpd


Re: LDCad 1.4b (twisted cables) - Philippe Hurbain - 2015-04-23

OK, I get it better now. Nonetheless I tried to reduce max merge to 1 on the 165° twisted cable, the torsion remains concentrated on the middle of the cable. Somewhat strange, the cable with middle CP (2x90°) looks more evenly twisted.

I love the "Select > Same part" and color as well as the "Select > Current step" feature and would like to know if there is a some sort of information available telling you how many parts/colors are in the selection?

Furthermore I'd like to know if there is a way to "hide" the steps? It would help making adjustments to bricks in an earlier step in reference to, say the current or number 10.

Re: LDCad 1.4b (win+linux) - Roland Melkert - 2015-05-08

Currently there is no direct way to hide steps, the current implementation basically uses 'hide if >curStep'.

But you can use the select everything in the current step (from a zero selection as all add functions add to to the existing selection). And then hide things using the normal part hiding ('h') feature. If you do that for all unwanted steps you end up with only the parts in the wanted steps.

I do have some additional stepping control planned, so I'll add this to the todo list.

I like your selection information idea, as there is currently only information about parts in the current step etc (using the 'I icon' in the lower right). I could extend that panel to include selection statistics and of create an additional part bin group like the current step info ones.

Philippe Hurbain Wrote:If you create a path flex part big enough (eg. my VEX track part), bounding box is large enough to prevent reaching the size handles when in 2D mode (you move the whole control point instead).
Sorry just noticed this part while working through the open bug/minor tweaks of this thread.

The editing rectangle can be hidden using 'p' just like in 3D mode, also the rectangle will be ignored if you're holding down ctrl while clicking the control point.

Good to know (I should have thought of "p" since I use it often in 3D!)


Re: LDCad 1.4b Documentation (hoses etc) - Roland Melkert - 2015-07-19

I've been working on the advanced editing documentation and just finished describing working with pneumatic hoses.

http://www.melkert.net/LDCad/docs/advEdit

More for this page is pending but I was wondering if this is somewhat understandable as I found it quite difficult to explain. So while I continue working on the shocks and grouping text please let me know your thoughts so I can adjust things if needed.

edit: I've also completed/uploaded the shock (spring) chapter.


Re: LDCad 1.4b Documentation (hoses etc) - Philippe Hurbain - 2015-07-20

Seems clear enough for me... but maybe I no longer qualify as a newbie? Wink
I learnt something in pneumatic hose section: the possibility to change control point style from Bezier to circle. Awesome for ropes!
Dynamic/rubber bands: Maybe you should tell what to do when you add circles in the wrong order? Talk about non-planar belts?
Pneumatic hose: Maybe more images at the beginning? perhaps you should number them to be able to refer to them easily in text.
Placement of shock absorber end: discussion of distance measurement and manual movement is interesting, but once the shock is properly oriented you can simply rely on part snapping of end on pin!

Typos, etc...
- over sized -> oversized (beginning of Submodels)
- them self -> themselves (beg. of nested)
- e..g a pneumatic hose -> e.g. a pneumatic hose/ dynamic parts of ether -> dynamic parts of either / when ever you drag -> whenever you drag (beg. of dynamic)
- "To do this you need to switch to the nested editing mode this is needed as we want to manipulate the band it self and not it's general location. " -> "To do this you need to switch to the nested editing mode. This is needed as we want to manipulate the band itself and not its general location. "
- "Thing rectangle can be used to move and rotate the selection much like the editing pin does." -> "This rectangle can be used to move and rotate the selection much like the editing pin does." (pneumatic hose)
-"Just compensate this by changing the grid so the pin points towards you again." Isn't it the viewpoint that we need to change? (shock)

Thanks for the corrections Philo.

Philippe Hurbain Wrote:I learnt something in pneumatic hose section: the possibility to change control point style from Bezier to circle. Awesome for ropes!
I added it as I thought not many people would realize bands and hoses use the exact same generator guess I was right Smile I'm also thinking about adding more kinds of points in the future e.g a spool point which automatically loops e.g. a rope n times around a radius to serve as the rope origin in cranes etc.


Philippe Hurbain Wrote:Dynamic/rubber bands: Maybe you should tell what to do when you add circles in the wrong order? Talk about non-planar belts?
I wanted to keep it simple but still give people the tools to do 99% of their models. Maybe I should add a new page for the advanced advanced stuff, e.g. a 'tips and tricks' page?


Philippe Hurbain Wrote:Pneumatic hose: Maybe more images at the beginning? perhaps you should number them to be able to refer to them easily in text.
Which step should have a picture, imho I gave all important stages a picture.


Philippe Hurbain Wrote:Placement of shock absorber end: discussion of distance measurement and manual movement is interesting, but once the shock is properly oriented you can simply rely on part snapping of end on pin!
You are right, did not realize this. I didn't even realize using the bottom pin before working halfway through the selection info method Smile. I will add it.


Philippe Hurbain Wrote:"Just compensate this by changing the grid so the pin points towards you again." Isn't it the viewpoint that we need to change? (shock)
The problem I tried to explain is e.g. 'top view' of the relative grid is at a different side then were it was in absolute space so to have the (visual) same grid you need to set it to e.g. sides. I'll try rewriting it.


Re: LDCad 1.4b Documentation (hoses etc) - Milan Vančura - 2015-07-21

Nice document, Roland. I was almost perfect 'testman' because I did not work with shock absorbers etc. before. So I followed all your examples and I may confirm they all are well understandable, I was able to learn everything you mention there. And I even learned some new tricks with Nested mode.

The only point the text was unclear to me was near the beginning of 'Nested editing' chapter where you refer to 'Insert into'. That confused me a little. At first, it's called 'Change insertion target' in 1.5Alpha3 (maybe you describe older version. 1.4 ?). And the trick with RMB at session panel was surprising for me so much that it took me some time to find that menu. Another confusing point is that a hot-key for that is 'n', same as for starting the nested mode. I know there cannot be a conflict because 'Change insertion target' makes sense only in the nested mode but that's clear AFTER one understands the problem, not at the learning time Smile

Also, I believe it would be easier to understand if one can simply make a selection and open a menu with all submodels to choose where to put it, comparing to the 'put to current level' workflow. BTW, what's 'level' here and why it is not written as 'submodel'?

The example with shock absorber reminded me another idea: I also found, same as Philippe did, that one can use part snapping instead of setting the absorber length in the menu. And so the generic idea: wouldn't be usable if one can not only move but also rotate the new part or selection in LDCAD with part snapping turned on? Just an idea - I do not have details solved yet (how exactly it should behave, in all which cases this would be useful etc.)
