Draft Layers

[nic]

Probably not, and it wouldn't help with the problem: "collect all {obj} and put them in a layer", {obj} being one of {sketches, walls, part, whatever}.

In my case, the layer's icon doesn't show any color.

Also, one question. How do you create a new layer in the Layers group?

Layers go automatically into the layer group.
I found that the tree doesn't request new icons all the time. Only at certain moments, for ex. when hiding/showing layers. Not sure yet how to attack that issue...

Hi Yorik,
I am glad to see Layers implemented.
I made an experiment about this.
I have not been able to solve the "update icon" issue.
It would be really great to be able to force icon update.
This little icon is a very "UX friendly" way to communicate some information to the user.
I suppose it means something like adding a "updateIcon" method to the viewprovider ???
I have never been much outside PartWB code, so I don't know all the mechanics up there .

Oh wow, I hadn't seen you had done something similar...
Will have a better look, there might be stuff to merge between the two.

For the icons, basically, the getIcon() method accepts two possibilities: a file path to an image, or XPM data. So I made another function that produces an XPM icon, simply by "drawing" it with Qt painting tools: https://github.com/FreeCAD/FreeCAD/blob ... er.py#L211
and then caching the XPM data so the getIcon() can serve it when needed without the need to recalculate it.

But indeed I haven't been able to force an icon recompute...

But indeed I haven't been able to force an icon recompute...

Don't have a Python example, but here is how I change the icon for the various dimension types. Might spark something for you.

Code: Select all

void ViewProviderDimension::updateData(const App::Property* p)
{
    if (p == &(getViewObject()->Type)) {
        if (getViewObject()->Type.isValue("DistanceX")) {
            sPixmap = "TechDraw_Dimension_Horizontal";
        } else if (getViewObject()->Type.isValue("DistanceY")) {
            sPixmap = "TechDraw_Dimension_Vertical";
        } else if (getViewObject()->Type.isValue("Radius")) {
            sPixmap = "TechDraw_Dimension_Radius";
        } else if (getViewObject()->Type.isValue("Diameter")) {
            sPixmap = "TechDraw_Dimension_Diameter";
        } else if (getViewObject()->Type.isValue("Angle")) {
            sPixmap = "TechDraw_Dimension_Angle";
        } else if (getViewObject()->Type.isValue("Angle3Pt")) {
            sPixmap = "TechDraw_Dimension_Angle3Pt";
        }
    }
    ViewProviderDrawingView::updateData(p);
}

Hello gents,

the implementation of layers seems really cool. Coming from the laser cutting point of view, this is exactly the method needed to have control over more complex .dxf cutting files.

in a more CAD oriented aspect, my experience with other CAD packages such as Siemens NX, shows that using layers is also very useful within a single part design, where layers can be used to separate or suppress the skeleton and master sketches. I'm sure down the line this will enable a part design workflow that will not phase new people coming from this background, which definitely propels FreeCAD front and center.

Just a positive thought on your work and tribulations.

Layers now have a Line Color and a Shape Color. I wonder if Point Color should be added (Draft_Point objects).

Hello,

I tried to use the new Draft layer feature but it does not work as described by Yorik at the beginning of this thread as the layer seems to "consume" the object. I did the following:

• Open an existing document which has a group tree (Site --> Building --> Floor --> objests ..)
• Change to the Draft bench
• Create some layers
• Changed to the BIM bench
• Dragged an object from a group to a layer with the mouse

Dragging the object to the layer removes the object from the original parent group which should not be the case. In fact it renders the layer concept unusable for controlling the display. Am I doing something wrong, or did I misunderstand the purpose of layers?

This is the build information (but I don't think it matters):

@yorik seems do not have proper access to the network recently, you may try to ping him so he may have a better idea which thread needs him

Ping

BTW, the FC info is good to have for ease of debugging by developers.
