The pallet of management of layers and pages:

The concept of layers is very useful in vectorial drawing.
That makes it possible to break up a drawing into homogeneous subsets.
Thus on a plan of architecture, one will be able to have the layers of structure, partitions, equipment, quotations…
And according to the posting or not of certain layers, the drawing can have several destinations.

With RealCADD you can have a drawing in “Plan” format, with layers or in format “Workbook” with pages.
The first case is the traditional mode. Second is particular in RealCADD.

The management of the layers and the pages is made by the intermediary of this pallet from which the contents are different for a drawing in “Plan " compared to that from a drawing in “Workbook”:

In this example, we are in “Plan” and we have 3 layers.
One creates a new layer while clicking on the “New” button and one removes them while clicking on the button “Delete” after having selected a layer.
The suppression also acts on a layer having of the objects and destroyed of course the objects present on the layer.
Each layer has a name, by defect Layer0 then 1,… but that one can modify by clicking above 2 times to pass in edition.
Each layer has also a scale of drawing “Scale” which one can also modify in the same way that the name.
This scale is the scale by defect which will be used for the drawing of the objects on the layer. If one changes this scale after having to create objects, they will not be modified. In spite of this scale by defect, one can individually assign a scale different to an object via the pallet from edition. But it is simpler to create a new layer with this different scale and to create the objects with this scale on this layer.
A layer is active, that on which will be created the objects, box notched in column A (Activ).
Each layer can be visible or not, box notched or not in the column V (Visible).
Each layer can be seen allotting a color by defect, box notched in the column C. All the objects of the layer will be automatically drawn with this color. That makes it possible to visualize well on which layer each object is drawn. The objects already present on the layer will change color.
To modify the color owing to lack of a layer, you must select it while clicking on its line, here Layer2 is selected. Thus RealCADD posts a rectangle of the color by defect of the layer under the button “Down”. By keeping the button of the mouse supported on this rectangle, you ridges to appear the pallet of choice of color. It is enough to release the button of the mouse when the cursor is on the desired color.
You can change the hierarchy of the layers with the buttons “Up” and “Down” or with the mouse into “taking” a layer in the list and by changing it place.
This hierarchy can especially affect your drawing with the objects having back color since they can hide objects of a lower layer.
You can also choose if the selections will be done on all the visible layers, Option “Selection on all the visible layers” notched, or only on the active layer, Option “Selection on all the visible layers” not notched and the same for attractions with the option “Attraction with all the visible layers”.
You have then the zone of management of the configurations of layers: Layer's layouts
A layer's layouts enables you to define among all the layers of your file, that which will be active by defect and those which will be visible.
You can thus with only one file have several drawings. That is interesting if several layers are common.
For example, with the same file you can manage a plan of architect and the associated plan of electricity.
For that, suffisament break up your drawing into layers, at least 3 for this example.
A layer “bases” for all the objects common to both drawings.
A second, “archi”, for the objects specific to the plan of architect.
And a third, “electricity”, for those specific to the plan of electricity.
Create 2 layouts: For that, make the layers “bases” and “archi' visible and the layer “electricity” invisible, type “plan archi” in the editfield “Name” of the “Layer's layouts” then click on “New”. The first layout is created. Now make the layer “archi” invisible and the layer “electricity” visible, type “plan elec” in the editfield “Name” then click on “New”. Your second layout is created. Use the local menu opposite “Display : ” to pass from one to the other.
The interest of this device is that the modifications made to the layer “base” are reflected on your 2 plans, archi. and elec.
The “Update” button, enables you to update a layout if you wish to modify the list of the visible layers or to change the active layer by defect.
The button “Clear” erases a layout of the list. But not associated layers.

The decomposition of a drawing in layers can appear constraining at the beginning but the advantages are numerous. One should not either fall into opposite excess and to have a too great number of layers even if RealCADD does not limit this number.  

Here, a file in mode “Workbook” is active.
The contents of the pallet are thus modified consequently.
The mode “Workbook” enables you to manage a file like a workbook or an album.
The layers are replaced by pages and only one visible (and active), is notched “A”.
The column “V” is replaced by a column “P” which makes it possible to indicate to RealCADD the pages to be printed.
The column “C” is removed.
The new pages are added after (under) the existing pages.
The order of the pages can be modified like the hierarchy of the layers, either with the buttons “Up” and “Down”, or with the mouse.
The lower part of the pallet is entirely different.
It enables you to manage the options of classification of the pages to the printing.
Notch “Number the pages” if you wish to number them during the printing.
The option “Except the first” can make it possible to avoid the classification of the title page of the workbook.
The 3 editfields enable you to define the headings and the first number of page.
The buttons radios fix the position of classification, T/L for Top/Left with B/R for Bottom/Right.
