Special Key Commands

Use of Ctrl Key

Table 1. Commands modified by the `<Ctrl>` key
Command	Description
Bolted Joint	The bolted joint command saves the last created bolt to avoid searching through the database if the next bolt is a bolt of the same type and length, etc. When you keep the `<Ctrl>`-key pressed during bolted joint command, the stored data are deleted and the program is forced to read the bolt data from a file.
Selected View	At Select View command you can set whether double-clicking quits the dialog. This setting is turned upside down when the `<Ctrl>`-key is pressed simultaneously.
Display Class	You can move the dialog of display and area classes lengthways. To return to the original status, keep the `<Ctrl>`-key pressed while the corresponding dialog is opened.
NC-Data	The `<Ctrl>`-key pressed while component parts for NC-creation are selected switches on the Debug-mode. Diverse graphical outputs are generated for NC-creation. They are rather meant for development, but sometimes they help to solve problems as well.
Positioning	If you enter the starting value of positioning, the next following value will be calculated. If you have alphanumerical values, which start with A, this is not possible, because you have to enter a `0` and the result will be an <A> displayed. A pressed `<Ctrl>`-key creates an <a>.
Work Frame	If you want to delete the list values of a dimension, you have to put the focus on it and keep the `<Ctrl>`-key pressed. Using the `<Alt>`-key allows elegantly editing of the field.
Positioning	At automatic positioning the subsequent calculation of component parts can be switched off using the `<Ctrl>`-key.
Modify Properties	Keep the `<Ctrl>` key pressed to modify the properties of exactly one component part.

Use of Alt Key

Table 2. Commands modified by the `<Alt>` key
Command	Description
general	The pressed `<Alt>`-key avoids working off the link update. No updates due to modifications are carried out. You can e.g. use this function to move parts without causing a reaction of the connected parts
Render Export	After the parts for Render-Export have been selected, a standard file name is used. The `<Alt>`-key permits file name selection.
Object View	The object view first creates a non-aligned view on the part. Alignment is made via `<Enter>`-button. If you press the `<Alt>`-key at selection of view direction, an aligned view will be directly created.
Free View	This is not carried out using Clipping. If the `<Alt>`-key is pressed, the global clipping distances will be used.
tentative snap	A pressed `<Alt>`-key during Object Snap selection inserts the reference points as well, if existing.
Handrail	At shape selection, the selection of the previous type can be taken over if you keep the `<Alt>`-key pressed while selecting the shape class (post, hand rail, knee-high guard rail, etc.). The same function is valid at modification of shape status, i.e. whether the corresponding shape is used or not.
Edit Drill Holes	At modification of drill holes, you can cancel the blocking of bolt fields by means of the `<Alt>`-key. These then can be deleted as well. Use this option carefully!
Truss Girders	Same function as for the selection of handrail shapes.
Lattice Girders	Same function as for the selection of handrail shapes. At insertion, the lattice girder is created with the entered width. The `<Alt>`-key creates a frame with the width of the entered points.
Select View	At Select View command, double-clicking on it activates the selected view. The `<Alt>`-key only moves to the corresponding UCS.
Hangar Frame	At insertion, the frame is created with the entered width. The `<Alt>`-key creates a frame with the width of the entered points.
Haunch	If you press the `<Alt>`-key while seizing the connection shape, a ceiling joist is carried out. If you press the `<Alt>`-key while seizing the supporting shape, the plate thicknesses are adapted to the supporting shape.
Ladder	The `<Alt>`-key causes that the ladder length is calculated from the third point.
Insert Shapes	If you choose Select Position, a pick into the drawing causes a rotation by 90°. The `<Alt>`-key causes a rotation by -90°.
Stiffeners	If you keep the `<Alt>`-key pressed during selection, the program is forced to an input via angles.
Copy	At selection via menu points instead of via dialog, the `<Alt>`-key causes a conversion of the setting, whether the operation is valid for group or not.
Working Areas	Activating one of the three list fields for distances permits comfortable input of the distances. If the `<Ctrl>`-key is pressed, the existing distances are deleted.
Line Cut	Pressing the `<Alt>`-key at selection causes not only a cut but, if need be, an adaptation, too.
Connect	Pressing the `<Alt>`-key at selection of the second shape avoids type check and everything is connected.
ArcShape	Osnap and Center: The `<Alt>`-key causes that the endpoints can be seized as well.
Bolt handless	If a bolt is modified using its handles, the `<Alt>`-key causes that the endpoints can be moved freely in space, otherwise only in bolt direction.
Purlin Connect	If the frame is modified, moving of the handles along a line causes the movement of the line without modifying the size. If the`<Alt>`-key is pressed, the line is moved and the size is modified depending on the neighbouring lines.
Plate handless	Same effects as purlin connection object.
Shape	Osnap and Center. The `<Alt>`-key causes that the endpoints can be seized as well.
2D Detail	In groups, the movement of an accessory part doesn’t cause new drawing of the main part. The modification will only be visible after regeneration. Pressing the `<Alt>`-key forces re-structuring of the group even without regeneration.
handles	For shapes, you can specify whether the length modification has only to be effected in shape direction or freely. Using the `<Alt>`-key turns this setting upside down.
