Defining a box

Define a box¶

As soon as you select the DEFINE BOX function, the properties bar appears.

In the case of box definitions, the contour must be closed.

Entry mode¶

There are 3 options for creating a box: Either you draw the contour immediately after starting the function or you have already drawn a polygon before calling the function and only "declare" it to be a box or it has already been selected. The function calls itself again and again in order to be able to draw several boxes one after the other. When you have finished creating the boxes, you can cancel the function.

Entry over contour¶

input_poly_
Entry is done by directly drawing a closed polygon. Once the polygon is completed by a second time clicking on the starting point, a box will automatically be created and the function ready to start a new polygon should you need to draw multiple boxes.

Entry over select contour¶

input_cont_
If you want to define an existing polygon for a box, you should make sure that the outline drawn is closed. The box can be generated by tapping the outline of the polygon.

Entry over selection¶

If a selection has already been made when this function is selected, a query appears as to whether this selection should be used.

Type of input¶

Lower and upper limiting surfaces by entry of height¶

3d_prop_box_height1_ 3d_prop_box_height2_
The height can be entered as a numerical value (in the currently set unit) in the input line or in the property bar.

Lower and upper limiting surfaces by entry of points¶

3d_prop_box_pt_input1_ 3d_prop_box_pt_input2_
With the help of the SNAP FUNCTIONS, the height can be defined directly by selecting a height point in the 3D model.

Lower and upper limiting surfaces over 3 points¶

3d_prop_box_points1_ 3d_prop_box_points2_
The area is defined using 3 points. The height is requested for each point. The definition of the three Z-coordinate points for the inclined extrude can be done anywhere on the screen and is not tied to the elements of a model!

Tip

Here, too, it is possible to select points directly in the 3D model. The clicked height is suggested above the input line and can be simply confirmed with Enter.

Lower and upper limiting surfaces over plane¶

3d_prop_box_plane1_ 3d_prop_box_plane2_
The position is defined by tapping an existing plane.

Change contour¶

contour_edit_
This can be used to subsequently modify the contour of the box. After you have clicked on the function, the 2D contour of the box is automatically displayed. Now change the contour with the normal 2D drawing functions according to your wishes. Make sure that the new contour results in a closed polygon again and terminate the function with the "Contour finished" button, which is visible at the top left.

Tip

If you click on a handle or gripper of the contour after selecting the plane, manipulation functions are also available directly in a toolbar or by pressing Tab on the cursor.

Define box¶

Workshop

Draw a rectangle then click on DEFINE BOX and set the Entry mode to Select contour. Set the base height to 0, the upper height to 100, the colour to 2 and click on the contour.

Several 3D definitions can even be created for the same contour. Now set the base height to 200, the upper height to 300, the colour to 3 and click on the rectangle again.

Tip

The individual parameters of the boxes can be modified with the element part selection mode.
In addition, when the box is activated, the 2D, 3D or all handles and grippers can be switched on using the Tab key.

To create a slanted box, set the Entry mode to 3 points. After you have drawn the rectangle, click on point 1 and enter a height of 0. Then click on points 2 and 3 and enter the heights 0 and -100. Proceed in exactly the same way for the upper height and enter the heights 100 and 200. Slanted levels are then produced.
