"Generate Section, Modify Section" palettes

Create Section (Sections task area)

Generate section (Derived from building structure)

When the

Create Section tool is open, click the

Remove/add elements button to select all elements you do not want to display in the section. This applies to all elements in the active drawing files.
The selected elements appear in the selection color. To confirm, right-click in the workspace.

To select a single element, click it.
To select elements in a selection rectangle, hold down the left mouse button and open a selection rectangle around the elements you want to select.
Some tools allow you to select all elements in the current document by clicking All in the input options or pressing CTRL+A.

To get detailed information on all selection options provided by Allplan, see Selecting elements, overview.

When selecting elements, you can use filters, which allow you to filter by element type or property. For more information, see Using filters.

When you click the button again, the elements you filtered out appear in the selection color. Click these elements and confirm by right-clicking to display these elements in the section again.
Click

at the end of the button to display all elements in the section again.

Select the drawing files for the section in the Select drawing file dialog box.
Note: The source drawing files must contain a clipping path. Otherwise, you cannot create a section.

Note: When you create a new section, the program has automatically selected the drawing files that are currently loaded (current drawing file and the drawing files that are open in edit mode and in reference mode).

Select the clipping path you want to use.
If you work with the

Create Section tool, you have the following options:
New...: Click this option to create a new clipping path in the current drawing file.
Select...: Click this option to select the clipping path by clicking it in the workspace or by entering its section identifier in the dialog line.

Select the layers you want to include in the section in the Layer filter dialog box. Click

to reset the settings selected in the Layer filter dialog box.

When you select this check box, the program updates the section automatically to reflect any changes you make to the model.

By entering factors, you can resize the section in the x-direction or y-direction or in both directions. A factor < 1 reduces the section; a factor > 1 enlarges the section.

If you work with the

Create Section tool, click to select the anchor point for the preview of the section.

You can define the reference scale of the source drawing files for the hidden-line image.

Click the button to open the Formats palette, where you can define settings for the hidden-line image.

Click the button to open the Label palette, where you can define settings for the section label.

You can choose to show or hide the section object. The section object is placed on the DEFAULT layer. The section object appears on the screen, but it does not appear in printouts.

You can use the

Modify Offset tool to change the extents of the section object. When you modify the model of the section object, you can use the input options to specify whether all edges are moved or the selected edge only.

You can use the

Show Clipping Path tool to display the section object of a section with or without the clipping path in a view or section.
You cannot use

Remove/add elements to show or hide the section object.

With this setting, fills represent surface elements in hidden-line images. The element color defines the fill color. If a surface is assigned, the surface color of the corresponding 3D element defines the fill color. Any textures are ignored.

With this setting, surface elements with textures are represented by bitmap areas in hidden-line images. Fills are applied to surfaces without textures (the fill color is derived from the element color or surface color).
Note: Bitmap areas are resized (cropped) correctly only in parallel projections (elevation and isometric views). But you can also achieve realistic images in perspective views with granular surfaces such as sand or plaster.

Use Consider transparency to display surfaces to which you have assigned transparent surfaces as transparent so that hidden surfaces become visible. This parameter is only available when you have selected the Only fills from colors or Create bitmaps from textures, fills from colors setting.

When you select the Consider light setting, the program calculates lights in hidden-line images in accordance with the settings for Light angle in view and Light angle to visible axis. This is not a sun study; the program idealizes the light situation!

Use Light angle to visible axis (length of shadow) to define how long the shadows are.

Use Light intensity to specify how many shades of color are used for fills and bitmaps. Enter a value 1 through 100 here. The smaller the value, the darker the image.

Use Fill-in light intensity to brighten up shadows and fills. Enter a value 0 through 100 here. When you specify an intensity of 0, the fill-in light is not calculated.

Select Show shadows if you want to display shadows. If you enter negative values for Light angle in view (left / right), the shadows are cast to the left. If you enter positive values, they are cast to the right. The smaller the value, the steeper the shadows. Use Light angle to visible axis (length of shadow) to control how long the shadows are in isometric views. The greater the value, the longer the shadows.

Click the button to open the Set Surfaces palette, where you can assign different colors to element colors. Allplan will then display the new colors - instead of the element colors - in the hidden-line image.

If you work with the

Create Section tool, you can save the result to a different drawing file. Click the Drawing files button to open the Select destination drawing file dialog box. Select an empty drawing file for saving the hidden-line image.


	alpha: light angle in view, -180° (left) to 180° (right) beta: light angle to visible axis, 0° to 90° (length of shadow))
