Raise or Lower Layers
Posted: Thu Mar 10, 2011 4:08 am
Commonly, in any sort of drawing program that supports layers, there is the ability to manipulate the layer ordering. I don't see that in QCad.
Layers seem to work peculiarly in any case. For instance, let's create two new layers: 'layer1' and 'layer2'. Now the Layer palette will show:
0
layer2
layer1
... and 'layer1' will be the frontmost (!?). Both of these features are exactly contrary to behavior in every other graphics application I can recall; the bottom layer in the palette is the top layer in the drawing; the newest layer is (almost) the rearmost.
I could tolerate unmovable layers if at least they were created back-to-front; since in a logical development of a drawing, more recent items may obscure earlier ones. I could tolerate the peculiar front-to-back layer creation if I could reorder layers later.
But apparently, we are stuck with immovable layers, created front-to-back. This makes the concept of layers something of a joke.
Related to this is the concept of entity ordering; even if two objects are on the same layer, one is on top of the other. There does not seem to be any way to send an entity to the front, to the back, or (better) one step in the ordering either way.
Am I missing something?
