Hi all,
I've been working on a new LDraw editor on and off during summer. I'm planning
to resume the project during my vacation after I've released a new LD4DStudio
version.
The project is more or less a study project to me in order to get some
experience writing multi-platform and CAD applications using C++.
I was hoping to get some ideas about features and editing behavior from the
people in the news group.
These are my own wishes/guidelines.
- Multi-platform (Windows, Linux, Apple)
- OpenGL driven
- High respect to the LDraw standards
- Native MPD support
- Group support
- Step editing
- Extremely customizable part bin
- Same for colors
- Still usable on relatively old hardware (OpenGL <1.5, CPU/VGA >5 years old
etc)
At the moment I have a very alpha version of it which loads and renders files,
it also has the fundamentals of a part and color bin/selection.
But the point I'm a bit stuck on is how to place the parts into the 3D 'world'.
I like the simple approach of the Lego designer and SR3D but I'm not going to
include auto snap/connection into the first version. Also I don't like the loss
of 'freedom' in e.g. Lego designer. So I'm leaning towards the old school grid
approach like ml cad uses.
But how to implement visible grid/guide lines in a 3D perspective display
editing enviroment? This is one of the most important design decisions regarding
to an editor I think. So I was wondering what some of the expert CAD program
users think/would like.
Any feedback/ideas/feature requests are welcome.
Greetings,
Roland

| Hi Roland, as author of SR 3D Builder I can say that the user interface is one of the most discussed feature of my application since what is easy/natural for me may not be for most of other users. During the many releases of the application I had to (...) (13 years ago, 31-Dec-10, to lugnet.cad)
