This topic will explain the Emboss Texture from Image, describe where to find it, the options found in it, and will provide links to related topics.

Emboss Texture from Image

Emboss Texture from Image creates an embossed texture using an image file. This feature is used to add machinable textures to an emboss model.

Navigation

To create an Emboss Texture From Image feature:

In the BobART tab, right-click Emboss Model, point to Emboss Texture, and click From Image.

The From Image dialog displays.

Parameters

Quick Access

Apply - regenerates the canvas to display the current parameters of the feature.
OK - regenerates the canvas to display the current parameters of the feature and exits the dialog.
Cancel - discards the updates to the parameters and exits the dialog.
Show or Hide all images in the graphics area - This option will show all hidden images in the graphics area. This same option will hide all images in the graphics area, besides the one being worked on for those features which utilize a loaded image.
Show or Hide the embossed BobART model in the graphics area - This option will show the hidden canvas in the graphics area. This same option will hide the visible canvas in the graphics area.

Attributes

Name- indicates the feature name that displays in the BobART tree. By default, it is automatically named by the feature type and number. Note that you cannot use the hyphen (-) character with spaces around it, as this is reserved for the automatic naming and will be removed. You can however use it without spaces, for example, Emboss-Body).
Color - click the drop down to select a Theme Color or Standard Color, or click More Colors to open the Select Color dialog. Select the desired color for the feature, and click OK to set the color, or Cancel to exit the dialog.

Application Type

These options are explained in more detail in the Application Types help topic.

Add	Subtract	Merge High	Merge Low

Add - Builds up on top of the existing features.
Subtract - Pushes down into the existing features.
Merge High - Builds up independent of the existing features and intersects as needed.
Merge Low - Builds up in place of existing features.

Image

Load Image - Clicking this button will launch the Open dialog allowing you to select an image to load. Once selected, the name of the file will appear below.

Current Attributes

Image Size

X - displays the length of the selected image along the X Axis.
Y - displays the width of the selected image along the Y Axis.

Canvas Size

X - displays the current length of the BobArt Canvas along the X Axis.
Y - displays the current width of the BobArt Canvas along the Y Axis.

Parameters

Pattern Size

Reset - resets the values to their default value.
Scale to Canvas - automatically scales the image to fit the defined canvas.
The following three options scale the texture image by a percentage of the original surface file size in the corresponding axis:
- Scale X %
- Scale Y %
- Scale Z %

Pattern Location

The following two options control the distance of the embossed textures by a percentage of the original image file in the corresponding axis direction:
- Spacing X %
- Spacing Y %

Important: It is important to know that the spacing works using the bottom left corner of the art surface as a reference position. Typing 100.0 means that the spacing between the reference positions are the width of the original image. Typing 50.0 indicates that only half of the original width is used for spacing, meaning that only half of the embossed texture is visible due to an overlap of the textures. Typing 150.0 indicates that the distance between the reference positions is one and one-half times the original width of the image.

Rotation Angle - allows you to change the angle of the texture surface. The value is applied to all instances of the embossed texture generated by this operation.
Shift Between Rows % - allows you to increase the spacing between embossed textures incrementally through the model. This percentage is added to each additional row.

Boundary Geometry

Selected Geometry

(Delete) - removes the highlighted item from the list.

(Delete All)- removes all entities from the list.

The list box will list the entities currently selected for the function.

OK - accepts any changes and regenerates the canvas. (The first time you click OK, the feature is created and added to the BobART tree.)
Cancel - cancels the creation of the feature (the first time that the dialog box is displayed). When editing the feature, this cancels any changes and closes the dialog box.

After defining the parameters, you use the Emboss Features in the BobART Tree to edit the feature as needed.

The Emboss Feature in the BobART Tree

When you finish defining the feature parameters and click OK, the feature is added to the BobART tree. You right-click each feature item in the tree to access a shortcut menu.

The Feature Shortcut Menus

Texture from Image

Right-click this item to access the following commands.

Edit - opens the Feature dialog for you to modify the feature parameters.
Delete - removes the feature from the tree. Regenerate to view the change in the model.
Suppress/Unsuppress - is used to remove the feature from the model or to restore a suppressed feature. To update the model, Regenerate.
Save As Component/STL - is used to save the feature as a component or .stl file. This saves the individual feature and not the entire model. The STL Save Option dialog box is displayed for you to set the tolerance. Next, the Save As dialog is displayed for you to select a location, name the file, and save it. The component can be used to create an Emboss from Component feature.

Boundary Geometry

Right-click this item to access the following commands for assigning a boundary. If no boundary is assigned, the texture is applied to the entire model (stock area).

Re/Select - opens the Selection Manager for you to select closed chains in which to confine the feature. You can select multiple closed chains. To confirm your selections, click .
Remove - removes any geometry assigned to the feature boundary.

Image

Re/Load Image - displays the Open dialog box for you to select a file type, select an image file, and click Open. The image is used to create the feature. Regenerate to view the change in the model.
Edit Image Using Paint - select this option to open the image for editing in the Paint program. When you are done editing, save the changes and exit the program. Regenerate to view the change in the model.

Generating the Model

After all necessary selections are made, you must regenerate to create the model.

To Regenerate the Model, do one of the following:

From the BobArt Tree, right-click Emboss Model, and click Regenerate.
From the feature dialog, click OK.

Note: Every time a change is made to an Emboss feature, you must Regenerate to update the model.
