Overview artcampro

The 3D Blend creates the relief form either inside a closed vector or between 2 closed vectors. The height and shape across the void is controlled by a series of standard, cross sectional forms or a user defined Z modulation curve.

Star Example

  • Open the model star-blend.art from D:\users\training\ArtCam Data

This model contains various vectors to demonstrate the 3D Blend relief options.

 

  • In Relief Editing select 3D Blend.nyy2

The 3D Blend assistant page appears providing a comprehensive range of the options. The 3D blend – relief is either generated from a single vector to a central or user defined point, or across to an inner vector using one of the Profile types, displayed in the form.

The final shape of the relief is controlled by a combination of the type of Profile and Height definitions selected.

The above options combined with merge highest, lowest, add, and subtract relief provides a very powerful command for the user.

  • Select the Star vector and shift and select the circle as well.
  • Select the Linear Profile option.
  • Select Border height as 0.
  • Select Inner height as 5.
  • Select Inner Vector Edge and tickFill Inner Vector.
  • Select Highest and press Create Blend.

The relief has a linear blend from the outer to the inner vector. It then continues at constant height (5mm) across the area inside the inner vector.

  • Select Undo (Ctrl + Z).
  • With the vectors still selected and the 3D blend pageopen, Untick – Fill Inner Vector Edge.
  • Select Highest and press Create Blend.

This time the area on the relief inside the inner vector is left open on the relief.

nyy7

  • Select Undo (Ctrl + Z).
  • With the vectors still selected and the 3D blend pageopen, select the Profile option Smooth.
  • Tick – Fill Inner Vector Edge.
  • Select Highest and press Create Blend.

A smooth relief is produced from the outer to the inner vector. It then continues at constant height (5mm) across the area inside the inner vector.

  • Select Undo (Ctrl + Z).
  • Select the outer star vector onlywith the Linear Profile optionselected.
  • Switch On – Select Point With Cursor and enter x 0 and y 10.
  • Select Highest and press Create Blend.

The relief is produced with an offset vector blend producing an offset centred star shape.

The next part of the chapter will compare the addition of different cross sectional, Selected Vectors numbered 1 to 3 as shown below.

Each vector will produce a different shape when scaled across the relief to the defined heights. The Selected Vector is always picked last.

  • Select Undo (Ctrl + Z).
  • Select the outer followed by the inner vector and with the 3D Blend pageopen, select the Profile option, Selected Vector.
  • Hold shift and select the cross section vector 1 from the 2D window.
  • In Blend from Border to: set Inner Vector Edge and tick the box Fill Inner Vector.
  • Select Highest and press Create Blend.

A new relief has been produced as the cross section, vector 1 scaled between the inner and outer vectors. It then continues at constant height (5mm) across the area inside the inner vector.

  • Select Undo (Ctrl + Z).
  • Select the star vector, shift select the circle vector and then thecross section, vector 2.
  • Select Highest and press Create Blend.

The new relief has been produced as the scaled vector 2 between the inner and outer vectors. It then continues at constant height (5mm) across the area inside the inner vector.

  • Select Undo (Ctrl + Z).
  • Select the star vector and shift select the cross section, vector 3.
  • Select Middle of Border Vector.
  • Select Highest and press Create Blend.

The shape of the relief is controlled by cross sectional, vector 3 running from the outer star vector inwards as well as from the centre outwards. The maximum height (5mm) occurs exactly half way between the outer star vector and the centre.
