Edit Graphics (Meshes)

Last modified: Aug 28, 2018

The Edit Graphics (Meshes) component tab contains tools for editing separate parts of components, or meshes, as well as whole components. These tools let you take full control of the editing process. A Mesh is a graphical element that can vary in size. An entire table can make up one mesh, while only a table leg makes up another mesh. In Edit Graphics, all operations are performed on a mesh level.

The tools are divided into the following fields: Set/Revert, Tools, Workplane, Copy/Cut, Stretch, Mesh Split/Fuse and Unite/Detach.

 

Properties

Set your preferences for working with Editable components:

EditGraphicsPropertiesDialog

 

Select

There are two buttons for selecting meshes; Single mesh select which selects an individual mesh, and Component meshes select which selects entire components as a group.

EditGraphicsSelectOptions

 

Set/Revert

The Set/Revert field contains three basic tools: Make editable, Revert and Graphics only.

 

Make editable

To be able to use most of the features on the Edit Graphics (Meshes) component tab, you first need to click the Make editable button and then click the component. This places the component in edit mode.

MakeEditableButton

 

Revert

Clicking the Revert button resets a component to how it was before it was made editable. This discards all changes made to the component and takes it out of edit mode.

RevertButton

 

Graphics only

This tool removes all information, such as price, description and snapping and only leaves the graphics.

GraphicsOnlyButton

 

Tools

A number of tools are available, enabling you to take full control of the editing operations that you wish to perform.

When using the Rotate and Move tools, it may be difficult to select the desired mesh. Therefore, an input box with the option Lock target is displayed. When you have selected the desired mesh, you can quickly check the Lock target box by pressing the Space key. This will prevent the selected mesh from being accidentally deselected when you perform the rotation or move operation.

 

Rename mesh

The Rename mesh tool is used to help you when you are applying materials. If you have certain meshes that will be a different material, it will be easier to identify them if they are named. Some meshes already have names associated with them but many do not.

RenameMeshButton

To rename a mesh, follow these steps:

  1. Switch to Single mesh select mode.
  2. Select the mesh or if you wish to select multiple meshes, use the Shift key to select them.
  3. Click the Rename mesh button and enter a name.
    RenameSelectedMesh

When you apply  materials, you will see the mesh name listed making it easier to apply the correct material:

Delete mesh

You can choose to completely delete a mesh, which is done with the Delete mesh tool.

DeleteMeshButton

To delete a mesh, follow these steps:

  1. Switch to Single select mesh mode.
  2. Select the mesh you want to delete.

Click the Delete Mesh button.

Rotate mesh

If you need to rotate a mesh on a component the Rotate mesh tool has to be used. The rotation tool lets you pick an arbitrary rotation point, either horizontal or vertical, and rotates the component around this point.

To rotate a mesh on a symbol, follow these steps:

  1. Switch to Single mesh select mode.
  2. Select the mesh or  meshes you want to rotate.
  3. Click the Rotate mesh button.
  4. Move the mouse to the selected mesh. A pink circle snaps to the mesh and is your rotation point. Use the space bar to select plane in the blue input box in the upper right corner, and then click once to attach the rotation point to the mesh:

Move mesh

Meshes cannot be moved by the normal drag tool and position tools because they are still part of a larger object. Instead, the Move mesh tool has to be used.

MoveMeshButton

To move a mesh, follow these steps:

  1. Switch to Single mesh select mode.
  2. Select the mesh or meshes you want to move:
    MoveMesh1
  3. Click the Move mesh button and again click the mesh you want to move.
  4. Start moving the mouse in the desired direction. You can use the input box in the upper right corner of the screen to either:
    • type in the distance and angle you want to move the meshes
    • select a base point and a second point or the distance and direction
      MoveMesh2MoveMesh3
Tip!

  • After clicking the Move mesh button, you can press the Ctrl key while looking for the desired mesh. This can help find points that are otherwise hidden.

 

Mirror mesh

You can use the Mirror tool to mirror a mesh along the X, Y, or Z axis.

MirrorMeshButton

To mirror a mesh, follow these steps:

  1. Click the Make editable button and then click the component that you wish to modify. The component is now editable.
  2. Switch to Single mesh select mode.

  3. Click to select the mesh or meshes that you want to stretch. You can select multiple meshes by pressing down the Ctrl key and clicking each mesh. Selected meshes turn yellow.
  4. Click the Stretch button.
  5. Move the mouse pointer to the drawing area in either the 2D view or the 3D view. The mouse pointer snaps to the selected mesh and CET Designer uses a red indication to show where you can stretch. An input box with the following fields appears in the upper right corner:
    • L, H, W – The overall length, height or width.
    • Dl, Dh, Dw – The amount the length, height or width is changing.
    • How many Auto planes are activated.
    • Centered – If the items stretches in one way or both.If you do not turn on any Auto planes or insert any cutplanes (explained below), the component will scale evenly.
  6. Click once where you want to make the stretch.
  7. Move the mouse pointer, without pressing down the mouse button, to stretch the component to the desired size.
  8. Click once to confirm the stretch operation.
  9. A new red indication is now attached to the mouse pointer letting you repeat steps 5-8.
  10. When you are done, press the Esc key on your keyboard or move the mouse pointer outside the drawing area to release the Stretch tool.

 

Cutplanes

A cutplane works as a divider between different planes and can be inserted into a separate mesh.

  2. Make sure that the Single mesh select button is selected.
  3. Click to select the mesh or meshes that you want to add a cutplane to. You can select multiple meshes by pressing down the Ctrl key and clicking each mesh. Selected meshes turn yellow.
  4. Click the Cutplanes button.
  5. Move the mouse pointer to the drawing area in either the 2D view or the 3D view. The mouse pointer snaps to the selected mesh, and a blue cutplane is visible.
  6. Move the mouse pointer over the mesh to get the cutplane in the right position. An input box where you can click to select X, Y or Z direction appears in the upper right corner. You can also use the space key on your keyboard to change the direction. You can also use the Remove button in the input box to remove an existing cutplane.
  7. Click once to add the cutplane. A new cutplane is attached to the mouse pointer. Keep adding cutplanes until you are satisfied.
  8. When you are done, press the Esc key on your keyboard or move the mouse pointer outside the drawing area to release the Cutplanes tool.
  9. Stretch the mesh as needed.

 

Mesh Split/Fuse

In the Mesh Split/Fuse field there are two useful tools for separating and combining meshes in various ways. These tools are also accessible from the Mesh dialog.

 

Split Mesh / Fuse Mesh

The Split Mesh tool can be used for separating meshes that are often grouped together, for example the legs on a table. This gives you more freedom to manipulate the meshes as you wish.

FuseMeshesButtonSplitMeshButton

example1_split_meshes.png example2_split_meshes.png
Table legs are often grouped together as one mesh. After splitting, all table legs are turned into separate meshes.

 

To split and fuse meshes, follow these steps:

  1. Click the Make editable button and the click the component that you wish to modify. The component is now editable.
  2. Make sure that the Single mesh select button is selected.
  3. Click the Split mesh tool. In the gray input box, you can select to split on Piece, Surface, or the X/Y/Z planes.
  4. Click the mesh you want to split, in our example above one of the table legs. Selected meshes turn green.
  5. When you are done, press the Esc key on your keyboard or move the mouse pointer outside the drawing area to release the Split mesh tool. When making a Single mesh select, you will notice that the table legs are now separate meshes.
  6. To fuse meshes into one unit again, press the Ctrl key and click each mesh that you want to fuse. Click Fuse meshes. The meshes are fused into one unit.
Note:

  • The Fuse tool can only be used on meshes belonging to the same component.
  • When using the Split mesh tool, it may be difficult to select the desired mesh. Therefore, an input box with the option Lock target is displayed. When you have selected the desired mesh, you can quickly check the Lock target box by pressing the Space key. This will prevent the selected mesh from being accidentally deselected when you perform the split operation.

 

Group/Ungroup

If you want to group several meshes within one component, you need to use the Group tool to create a unit. When you want to separate the meshes again, use the Ungroup tool. These tools are also accessible from the Mesh dialog.

GroupMeshesButtonUngroupMeshesButton

  1. Click the Make editable button and the click the component that you wish to modify. The component is now editable.
  2. Make sure that the Single mesh select button is selected.
  3. Click to select the meshes that you want to group. You can select multiple meshes by pressing down the Ctrl key and clicking each mesh. Selected meshes turn yellow.
  4. Click the Group button.
  5. When you are done, press the Esc key on your keyboard or move the mouse pointer outside the drawing area to release the Group tool. When making a Single mesh select, you will notice that the meshes you selected have been grouped together.
  6. To ungroup meshes again, select the group and then click the Ungroup button.
Note:

  • To group or ungroup meshes from different components, use the Unite and Detach tools.

To the top

 

Unite/Detach

You can use the Unite and Detach tools to group and ungroup meshes from different components. Detaching a group of meshes will result in freestanding meshes that can be modified. Functionality then only remains for the original component but is lost in new components.

 

Unite Meshes

Uniting meshes either creates a new component of is added to an existing component. Perhaps you have copied the handles on a pedestal and added them to a pedestal that you have edited. After making the modifications, you can create a unit of that pedestal along with the handles. To keep the snap points and product information from the original object, select it from the list or you can select New snapper. If you select New snapper, there will be no product or snapping information attached to the symbol.

UniteMeshesButton

To unite meshes, follow these steps:

  1. Click the Single mesh select button to switch to single mesh select mode.
  2. Click to select the mesh or meshes that you want to unite. You can select multiple meshes by pressing down the Ctrl key and clicking each mesh. Selected meshes turn yellow.
  3. Click the Unite button. The Group to dialog box opens.
  4. You can add your unit as a new component, or create a new snapper.

 

Detach Meshes

To break apart a combination of meshes, you need to use the Detach tool. This will result in freestanding meshes that can be modified.

DetachMeshesButton
