Define Sectional Views (3-D)

Views > New > New sectional view

HiCAD allows you to create sectional views in a wide variety of versions, e.g. expanded, with lateral restriction, with or without identification of the section path and so on. The section path is based on a sketch.

This function will always be applied to the active view. Please select the desired view before you call the function.

Once you have called the function, the New sectional view dialogue window is displayed. Then proceed as follows:

1. UnderType, select the type of sectional view you require.
2. Specify the Sketch for the section path - either by constructing a new sketch or by identifying an existing sketch.
3. Define the options for the Identification of the section path.
4. Use the Preview button to check the identification you have chosen.
5. Select the settings you want for the Hatching.
6. Click Create to generate the sectional view.
7. Specify the position of the view on the screen. While positioning the sectional view, i.e. as long as the view "attaches" to the cursor, you can choose a new reference edge for the alignment by pressing the right mouse button and choosing Change edge for alignment. Note that the side on which the section is made (i.e. the line of vision) is defined by the alignment direction!
8. If you have previously activated the Limited option in the New sectional view dialogue window, the Limit sectional view dialogue window is displayed. Here, you can change the zoom and the hatching. The current size of the section is displayed as a rectangular sketch in the drawing, in parallel with the dialogue window. The size of this rectangle is determined by the sketch and the height of the drawing or the parts to be cut.
9. If you want the sectional view to be created in the size indicated, click the Apply button in the dialogue window.
10. If you want to change the restriction of the sectional view, use the Sketch function to change the sketch shown and click the Apply button.

Example: Sectional view, unfolded

3-D model, axonometric view	Top view with section contour (1) and line of vision (2)
Unfolded section

Example: Sectional view (not unfolded)

(1) Original with sketch, (2) Sectional view without section path and annotation	Original (1) and sectional view (2) with section path, angle description and caption
Limited sectional views with bounding sketch determined by HiCAD

Example: Sectional view with depth limitation

(1), (2) Original in axonometric view and in top view, (3) Sectional view with depth limitation, (4) Sectional view with depth limitation and lateral limitation

Please note:

• Limited sectional views are also possible for planar sections: Activate the Only cut surface and the Limited options.
• In the case of "standard", i.e. non-expanded sectional views, the sketch for the section path must fulfil the following conditions:

• The sketch must not be closed and must not contain any curved lines. The "imaginary" extensions of the sketch elements must not intersect.
• The sketch must be connective and consist of more than one line.

• In the case of expanded sectional views, the sketch for the section path must not contain any curves (circles, arcs, ellipses etc.)!
• Auxiliary geometries contained in the sketch will be considered for the generation of sectional and detail views. This means that edges marked as auxiliary geometries will have no influence on the geometric representation of the sketch.
• When sectional views are generated, the section body is internally lengthened backwards by the tenfold diameter of the drawing. This also enables parts that are added at the back, e.g. when updating the sectional view, to be taken into account. If no section path that can be hidden by parts located in the foreground has been drawn, this lengthening is also performed forwards.
• A part's section behaviour, which is defined with the Cut, In sectional view + cut-out function determines whether it is taken into account in the sectional view.
• The sectional view created is automatically linked to the starting point.
• When the section surfaces are displayed, the settings of the Hatch section+cut-out function may possibly be used.
• Note also the Properties > Hatching functions in the context menu of the drawing. This function enables you to shade all section surfaces – irrespective of view - either according to material catalogue or by means of parallel lines.
• If you have generated the sectional view with a caption, it is automatically updated when the view is rotated.

• The representation of the section path and the identification of the section in the original view can be set in the Configuration Editor, at Drawing > Views > Ident > Sections. There, you can specify the position of the annotation (identification) at the section path and the line colour, line type and layer in the original view.

Please note that these settings do not apply to headings (captions).

• The behaviour of sectional views during Boolean operations can be influenced by the settings in the system file KRPMOD.DAT in the HiCAD sys directory. There, you can specify, at:

REM Keep or delete old sectional views after Boolean Operations: 0: Keep, 1: Delete

0

whether the old section objects(i.e. the section objects that existed before the Boolean operations were applied) (0 = Default) are to be retained or deleted. The corresponding sectional views will be marked in the ICN with a strikeout view name, indicating that the view is not up to date.
