Tool for inserting a threaded fastening from library nanoCAD Construction 25.

Procedure

1. Specify the starting point of the threaded fastener in the drawing.

2. Specify the end point of the threaded fastener, the "Fasteners" dialog will open. When inserting, tools are available to select the direction of drawing. Specifying the start and end points defines the centerline of the fastener. The intersected lines make up the thickness of the part package being fastened.

3. In the "Fasteners" dialog box, customize the look of the threaded fastener.

Note:

The thread fastener insert dialog automatically saves the last selected template and thread diameter.

4. Confirm the settings with the "Apply" button, or with the "OK" button if you want to close the dialog at the same time. A threaded fastener will be built.

Editing a threaded fastener

You can edit a threaded fastener by editing the "Threaded fastener" object, or by editing individual parts included in the threaded fastener.

When editing, you can change the composition, diameter of the threaded fastener, as well as the parameters of the individual parts that are included in it.

To open the threaded fastener setup dialog, apply any of the standard editing tools to the centerline of a group of parts.

If tooltips are enabled in nanoCAD Construction 25 settings, then when you hover the cursor over the centerline, the "Threaded fastening" tooltip appears.

Template list panel

It is possible to save a threaded fastener template for later reuse of assemblies with the same set of parts. To work with templates, use the buttons at the top of the dialog box, and below is a list of available templates:

Button "Create new template" adds a new empty template. When creating a new template, the required number of holes is automatically added depending on the number of lines crossed in the drawing.

Button "Delete template" removes the selected template from the list. "Editing template" stores the current setting of the threaded fasteners. It cannot be removed.

Button "Selecting insertion point" is intended to reselect the insertion point and the length of the threaded fastener in the drawing.

Button "Manually select holes length and placement" opens a window for setting parameters of a package of connected parts.

LMB clicking on one of the cells in the "Parts type" column switches the part / gap:

In the "Parts width" column, the thickness of the corresponding part (or gap) is set. After setting the parameters of the connection package, close the window with the "OK" button.

The context menu of the list of templates contains the commands:

• Add folder
