Removing rounds

The  Rounds tool provides a quick and easy way to remove rounds from an object. It is similar to the Fill tool, except with the Rounds tool, you can only select rounded edges.

The image below shows an example of well-formed rounds, on the left, and poorly formed rounds, on the right:

Before you begin:

• You will have a greater chance of success if you remove only a few rounds at a time. If you spend a lot of time removing rounds, you may want to review SpaceClaim's tutorials or technical support information,online at SpaceClaim.com for advanced techniques you can use when removing rounds.
• Closely inspect your model from various angles and zoom levels, so you can best determine the areas of rounds you want to remove. Each area of a model is unique, and different areas may require different approaches to round removal.
• Select the round's or round group's shortest edge first.

To ensure accurate and complete round removal, remove the rounds in the reverse order in which they were created, as shown in the example below of a model with colored rounds:

To remove rounds

To split and partially remove a round:

1. Click Rounds from the Remove group on the Prepare tab.

   Avoid splitting into a round. Instead, split on either side of it. You may need to split and partially remove one or more rounds before adjacent rounds can be removed, especially when two or more rounded faces meet along an edge or vertex. The rounded face is split and filled in the middle. To select faces or capping faces, use the Faces tool.

2. Hover over one tangent edge of the rounded face to display the round's split lines. These lines show you a visual indication of where the round will split, as shown below. You can move the split lines by moving your mouse.

    

If necessary, from the Options panelArea of the user interface that enables you to modify functions specific to tools., change the Cap width option to adjust the percentage of the round face that is removed.

• Click on the edge to split the rounded face.
• Select the rounds you want to remove:

• Click an object in the Structure treeDisplay in the Structure panel that shows you each of the objects in your design. You can expand or collapse the nodes of the tree to view the objects. You can rename objects, create, modify, replace, and delete objects, as well as work with components. to select all rounds on the object.

• Select a round face in the design area. You can hold Ctrl and select faces or draw a box to select multiple faces.

• Ctrl+click to deselect a face.

• From the context menu choose Select > Using Box. MoveA tool used to translate or rotate geometry. your mouse over the area you want to remove to identify the parts you want to select. Draw the selection box around the area. You can only select round faces while this tool is active.

To select faces or capping faces, use the Faces tool.

1. Click the Complete tool guide.

   SpaceClaim removes the rounded faces you selected and replaces them with a sharp edge.

Tool guides

The following tool guides help step you through the process. Use the Tab key to cycle through them. As soon as the tool guide switches, the cursor may change to reflect the active guide.

Options

The following options are available in the Options panel:

• Auto-shrink fill area: Select this option to split round faces where they can't be removed when you select a chain of rounds and it cannot be filled in its entirety. The rounds will be partially removed.
• Cap width: The percentage of the width of a round that is removed when you click on an edge of an existing round. The splits are previewed as the cursor is moved along the round tangent edges.

Using other tools to remove rounds

• As an option, when removing rounds, you can also use the Replace tool from the Edit group on the Design2D or 3D model that contains at least one top-level component. tab, to replace one face with another. You can replace multiple faces with a single face, replace a single face with multiple faces, or replace multiple faces with multiple other faces.

Progression using a face to remove a round

• Try using the Sphere tool from the Insert group on the Design tab. Using this tool, you can create a round sphere and place it at difficult geometry junctions. Once in place you can use the sphere to split the junction in order to remove the round. In some cases, you may want to create a chain of two or more spheres to help with removing larger or more complex rounds areas.
• To avoid trouble with removing spheres, it's good practice to fill the sphere immediately after you remove the rounds on either side of a sphere or sphere chain.
