Assign a color for the active camera and its view area in the Graphics window and in the 3D World window.
The fill of the view area projections will be colored only if the pixel density visualization of this camera is disabled.
The color is assigned regardless of the line type of the camera.
White color means no color assigned. In the case of the assigned white color (no color assigned), if the line type of the camera equal the default line type for camera icons specified in the Options box, the colors of elements for such a camera are taken from the Options box> Lines> System Lines. By default, cameras are assigned line type number 21. If a different line type is assigned to the camera, the colors of elements for that camera are taken from the assigned line type.
Position of the button at the moment of saving the camera determines how the camera will be painted when it is not active.
If there are selected cameras on the layout, except for the active camera, then a magenta frame appears on the button and the button controls the color of all selected cameras simultaneously.

Fill in different colors regions on the view area projections of the active camera, depending on the pixel density on the far bounds of these regions. Colors of the regions and the boundary values of the pixel density are determined by the pixel density pattern assigned to the camera. In the Pixel density box you can edit the patterns and assign them to cameras.
Drop-down menu: 1. Discrete colors - fill the regions in discrete colors in accordance with a pixel density at the far bounds of the regions.
2. Gradient - fill the view area projection in gradient color according to the pixel density at each point on the projection.
In case of gradient color is chosen, the colors at the far region bounds equal to the colors of the pixel density pattern, but between the bounds color changes smoothly, as well as real pixel density. Gradient reflects the pixel density more accurately and looks impressive, but discrete colors are more intuitive and easy to use.
Calculation of gradient demands a lot of resources and increases redraw time.
3. Off. - don't display pixel density
In the Dome mode the Pixel density is calculated without taking into account pan and tilt angles of camera. It is assumed that the camera can pan and tilt freely, and pixel density is calculated at the center of the field of view.
A button state at the moment of camera saving determines whether the pixel density of the camera will be displayed when this camera is inactive.
If selected cameras exist on the layout, except the Active camera, this button changes view () and operates the visibility of pixel density of all selected cameras simultaneously.

Paste the objects from the VideoCAD internal clipboard. After clicking this button specify the base point of paste in the projection being clicked when cutting or copying.
It is possible to paste into different layouts, paste cables of one camera while another camera is active (in this case the pasted cables belong to a camera which is active during paste), and to paste any quantity of constructions, 3D objects, cameras, illuminators, texts and cables at a time.
Be careful when copying and pasting cables. You can copy only cables of Active camera, and when pasting, these cables will belong to the camera which is active during pasting.
If a camera is being pasted a new camera with parameters of the pasted camera is created automatically. This is an alternative way to create new cameras.
Shadows in the Graphics window and in the 3D World are calculated for the active camera, but pasted camera doesn't become active. Therefore the view area of the pasted camera is displayed without shadows. To calculate shadows - activate the camera after pasting.
Pasting is always performed to the active layer. At the moment of placing new camera or pasting copied camera, its base height is set to the base height of the active layer.

Buttons of this group are used to perform measurements and constructions. The status bar in the bottom of the Graphics window and the Current construction parameter panel display the results of measurements. The constructions can be used for 3D modeling the video surveillance object, for specifying the required view areas, objects, obstacles, etc. Each construction is attached to the projection containing its initial point. The constructions can be moved, deleted, rotated, edited, copied, mirrored , scaled, changed draw order, hidden using the buttons of Edit group.
Constructions made in the horizontal projection are also displayed in the 3D Video and 3D World . At this, the line corresponds to a vertical rectangle, the point - to a vertical segment, the rectangle - to a parallelepiped, circle - to a cylinder, etc. Constructions are stretched throughout the height and become 3D objects.
Minimal and maximal height of each object are determined by parameters of line type, by which the construction is made. The heights can be set separately for each object, during constructing and editing by means of current construction parameters panel. Heights of constructions are calculated relative to base height of a layer to which the construction belongs.
Constructions are easiest to create vertical objects. To create oblique objects use the Inclined Rectangle tool. You can also turn vertical constructions into a 3D model. 3D models can be tilted and transformed. More complex objects can be modeled in SketchUP and imported in VideoCAD.
The colors of constructions are initially set by the line type of the construction. You can change the color before drawing the construction and when editing on the current construction parameters panel. In addition to the color or with the color, you can specify the material.
Constructions can be distributed by Layers. By changing parameters of a layer you can change some parameters of all constructions belong to the layer. At the moment of drawing, construction is placed on the active layer.
To enhance speed and convenience of drawing, VideoCAD uses global and local snaps.
The construction coordinates are displayed relatively to the chosen origin of coordinates. The coordinates of constructions belonging to one camera only (focal plane, optical axis, field-of-view size, test object,change view area upper bound) are always displayed relatively to the Active camera.
When choosing a button of this group a line type panelor a font type panel appear, allowing to change the line or font types. When double-clicking the panels the options box appears.
Above these panels the current construction parameters panel appears, by means of which it is possible to create construction, by setting its parameters.

3D models can be moved, rotated, copied, changed draw order as other VideoCAD objects.
The default height of the 3D models above the ground is determined by the maximal height of the line type which was chosen when the 3D model was being placed. The height can be set separately for each 3D model using the current construction parameters panel.
To change 3D model height above the ground, select the 3D model, then change line type or switch the 3D model to editing state by double clicking on it and change value in the 3D H box on the Current construction parameters panel.
By default the 3D models are on the ground and constructed by the line type with the number, specified on the Lines tab of the Options box. This line type has the maximum height equal to 0. Heights can also take on negative values, in this case 3D model plunges under ground. For example, to place a 3D model on a surface: construct the surface by the rectangle tool using line type with the required maximum height, place the 3D model on it, and then change 3D model line type to the line type of the surface.
In multilevel 3D projects heights are calculated relative to the base height of a layer the which the 3D model belongs. By changing the base height a layer you can move up or down all 3D models and constructions on the layer
In the Editing state using the Current construction parameters panel you can resize 3D models separately on axes. To do this, enter new values into X, Y, Z boxes during 3D model editing. If the box is marked, change of any size leads to proportional change of other sizes, thus model proportions are not broken. 3D model height above the ground is displayed and can be changed in 3D H box.
You can see how any 3D model will look at any point in space through the active camera using the 3D Test and 3D Test on View area bounds tools.
