(Solved) 0.18 two issues (treeview and zooming peformance)

[user1234]

Hello!

I am working with

Code: Select all

OS: Debian GNU/Linux buster/sid
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.15208 (Git)
Build type: Release
Branch: master
Hash: e02695b91fc8aa19e64594c12386104368809ebc
Python version: 2.7.15+
Qt version: 5.11.2
Coin version: 4.0.0a
OCC version: 7.3.0
Locale: C/Default (C)

and have two issues.

The first and newest: the tree view (only) panel is away. Is this intention? I think this was really useful. With the combo view i have no overview.

The second and longer issue, that a have already a long time, is a performance problem. If i zoom with the mouse in the model, the FPS goes extreme down. This is also when the model is clipped. But when i zoom with the mouse outside the model, it works fine. Working with larger models is almost impossible (or let us say damn hard). I have this issue longer, but no time before to report this. It is intependent from the the OpenGL vertex puffer setting. No anti aliasing. Models are rough (1% deviation). I think this is related to https://forum.freecadweb.org/viewtopic. ... 10#p260315.

Sorry for bad english.

This should be moved to Help.

Issue #1: I hope the Tree view hasn't been removed, I use it all the time on my desktop.

Issue #2: View->Standard views->Fit all should fix the clipping problem.

I confirm that Tree view and Property view have indeed been removed from View --> Panels in v0.18.

Not sure why. It might be accidental.

Pinging mlampert who recently added the new View --> Document Tree sub-menu, maybe he'd be able to figure it out?

And of course

Do you have insight on this? Thanks!

Hello!

This should be moved to Help.

I do not think so, because this is not about "how to use" FreeCAD, only my thought. But maybe you are right.

Issue #2: View->Standard views->Fit all should fix the clipping problem.

This *.gif is a "View-->ClippingView". I want so show that the performance issue is also here, when the mouse is in the model (or bounding box) in a clipping view. But thanks.

Sorry for bad english.

Moved to Help forum. These kind of topics belong there (well now it's rather "here" than "there").

The first and newest: the tree view (only) panel is away. Is this intention? I think this was really useful. With the combo view i have no overview.

The tree view and property view are still there but disabled by default. git commit 3d8b815834f
In order to get them back open the parameter editor and create the groups:
BaseApp/Preferences/DockWindows/TreeView with the boolean key Enabled set to true and
BaseApp/Preferences/DockWindows/PropertyView with the boolean key Enabled set to true.

Afterwards you have to restart FreeCAD.

Of course when many people still use the standalone tree/property view we can make the above settings true by default.

As a developer it's a pain when two tree views exist and you want to debug something in the code because things are always done twice which can be quite confusing sometimes.

The second and longer issue, that a have already a long time, is a performance problem. If i zoom with the mouse in the model, the FPS goes extreme down. This is also when the model is clipped.

As a very first step I would check for updates of the graphic driver.

I think this is related to https://forum.freecadweb.org/viewtopic. ... 10#p260315.

The issue there was about a special mouse with additional settings the user forgot to change.

With git commit d86c83d6c5 the two views are back again by default but you must follow the above steps and manually set the keys to true (or delete your user.cfg).

Thanks for that. Works fine.

One general question, can a task view only implemented? If someone wants a combo view, you can dock it like all others windows (like i did for the combo view and the property view, see screenshot). So you need only one tree view in the sourcecode to maintain.
For me, as example as an user, want always see a tree view and a task view, but never combined in a tab. If i have a running task, i always have to switch back and forth. (For exemple clipping view, that i use extreme.) And with the combo view i have two tree views and i think this interfering. Just a thought, no offence.

Checked before (and now). I have the latest driver.

Code: Select all

01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Granville [Radeon HD 6850M/6870M] [1002:68a8]

xserver-xorg-video-ati 1:18.1.0-1 from 2018-09-18
With radeontop i looked to the grafic card performance. While zooming the card did not work hard.

But when i zooming the CPU goes up. I want to show about that a *.gif, but they are always to big to attach. So i hope the screenshot is enough.

One thing what is also interesting. If the mouse is over a simple part like a cube or a cylinder, it is faster. But if the mouse over a chamfer, radius, cone or a part with more features, it slows extreme down.

Sorry for the many *.gif, but a dynamic issue is hard to show.

At least the version with i do the screenshots:

I agree it would sometimes be nice to have a possibility of using a standalone Tasks panel (QDockWidget). Likely named Tasks view. Wanted to propose something like that in the past myself. As for duplicate code. Werner added Search capability to the Tree view (Combo View). I am guessing that left the standalone Tree view widget without this functionality. As he would need to implement such functionality twice.

How about if there would be a setting in Preferences. To use a Combo View or a set of standalone widgets (Tree, Property and Tasks view). This would be acknowledged on FreeCAD start. And as functionality such as Tree panel would be put inside Combo View or in a set of standalone individual QDockWidgets. No duplicate code would be needed anymore after? End users could use the preferred layout of the mentioned widgets.
