Create Shape

The Create Shape tool allows the user to create Components based on one or more closed vectors. The vectors can be selected either before the icon is clicked or after the form is open. The user works through the form specifying the profile and strength of the shape and modifying options to govern its height. There is also an option to Tilt the shape on an angle. Once any of the parameters have been defined the shape can be previewed by hitting Apply.

This shape can be easily changed by altering the parameters in the form and hitting the Apply button to update the preview. Once you are happy with the shape created then you have two choices, to Start New Component (which will save your current component and start a new one) or Close the form.

Changing values with the sliders on the form will immediately update the 3D view when you release the slider. If you make changes to the edit fields such as Angle or Base height, pressing the 'Space' bar on your keyboard after you have finished entering your value will apply the changes and update the 3D preview or you can hit the Apply button again.

If you select another vector, then the current shape will be discarded, so remember to hit Start New Component if you want to keep a copy of it.

The Angle setting will define the angle of the edge of the rounded or angled profile shape - the higher the angle, the steeper the shape. Angular shapes can have a maximum angle of 89°. The slider bar to the right can also be used to change this as well as typing a specific angle into the form.

The custom shape profile uses a vector to define the profile rather than using one of the standard profiles.

To use the custom profile option a selection of closed vectors, plus an additional open vector representing the profile, must be selected.

When using a custom profile, the form the final shape will take comes from considering the shape above the line joining the end points. For this reason the profile vector should usually have a leg.

When creating a shape using both external and internal vectors, the resulting component will have both external and internal corners. In this scenario, with this option unchecked the internal sides of the resulting shape would curve into the centre line at which the two sides meet if you draw a straight line from the top peak of the corner to the base of the shape, creating rounded internal corners.

Enabling this option by checking the box will mean that these internal sides will be comprised of a completely straight sided skeleton until both sides converge at the centre line of the corner, creating a defined sharp crease and an internal corner which will come to a sharp point as if the corners have been perfectly mitred.

This is best demonstrated with examples that use a polygonal base vectors;

Checking ✓ this option limits the height of the shape by scaling the shape up or down while retaining its general specified profile. It is scaled to the height entered in the Height area of the form which becomes available once this option is selected. The slider can also be used to change the final height.

This option applies the selected profile across the selected vectors. It blends to the profile from the outside of the vectors to the inner vectors

The sweep option takes the profile chosen and sweeps this profile around the selected vector, blending the profile inwards, but not distorting the original profile. This is particularly useful when used in conjunction with the custom profile.

When this option is checked ✓ the user can set a direction and angle to tilt the shape up at an angle in Z. The first part of this operation (once the option is checked ✓) is to press the Set Anchor button - then click two points in the 2D view.

The first click specifies the point which will remain at zero (the pivot point of the tilt).

The second click specifies the point that will be tilted upwards by the specified angle (the point that will be raised up).

The default angle (10°) can be edited by clicking the arrow next to the value and using the slider or by typing in a specific value and hitting the Space Bar on the keyboard to apply the angle.

This section includes options to allow you to name your Component and control the way it will be combined with other objects in the Component Tree.
