Activity: Object Tree Basics and Groups

The objective of this activity is to learn more about the tree structure and its hierarchy. Browsing the Object Tree Creating Compound Resources Creating and Working with Groups Browsing the Object Tree

1. Successively clicking the display status squares (Blank and Display ) next to the nodes on the Object Tree viewer causes the displaying or blanking of entities in the Graphic Viewer. Note: When you click the box next to a node, it switches between a filled box and an empty box. When the box is fully filled, the object is completely displayed in the tree. When it is partially filled, the object is only partially displayed in the Graphic Viewer When you see an X in the box, no 3D data is available. 2. As mentioned previously, clicking the + or - icons next to a node expands or hides the next level, respectively. It is useful to expand the tree fully to display all levels, since some entities are nested within subcomponents. It is important to learn to identify the entity icons. Note: Expanding Trees: One level of a tree can be expanded by clicking the + icon next to a node in a tree. The [*] key from the Number Pad area of the keyboard (which is [Fn] —> P on an American laptop keyboard layout) can be used to expand all levels of the tree. We will also learn how to do this using the right-click menu in the next topic. Collapsing Trees: One level of a tree can be collapsed by clicking the - icon next to a node in a tree. We will also learn how to do this using the right-click menu in the next topic 3. Individual parts/resources or compound parts/compound resources can be added or removed from a group. . Complete groups can be moved by highlighting the

42


desired objects in the tree (with the left mouse button), then dragging and dropping it onto the desired location on the tree. Creating Compound Resources

1. In Object Tree viewer, select the first object in the Resources folder. Note: Only other compound objects can be used as the parent for a new compound object. 2. Select Modeling —> Create Part Resource —> Create Compound Resource

.

Note: A new CompoundResource1 object is created in the Resources folder of the Object Tree. Note: Whenever a new object is added to a study, it will be added to the bottom of the list of entities on the Object Tree viewer. 3. Pick the new CompoundResource1 object, press [F2], and enter My Compound Resource for the Name. Note: Nodes in the object tree (that are not read-only) can be renamed by first selecting them and second, clicking them again. A frame will appear around the selected text, which a new name can be entered Note: You can also press the [F2] key to begin renaming objects. 4. Drag and drop the desired resources on to My Compound Resource. Note: This compound resource will be stored back to the original resource tree and change its structure after eMServer Selective Update

43

is clicked.


Note: You cannot add both parts and resources to the same compound object. Creating and Working with Groups

Individual parts/resources or compound parts/compound resources can be grouped to establish additional hierarchy levels in the tree. If a group is selected and then shifted or rotated, the objects in the Graphic Viewer that are in the group will also be moved. Each object can also be shifted or rotated independently of the group. 1. Select View —> Viewer —> Logical Collections Tree. 2. In the Logical Collections Tree viewer select the Groups folder and select Tools —> Groups —> Create Group . 3. From the Graphic Viewer or Object Tree viewer , pick some parts or resources. Note: A group can contain any combination of other groups, resources, compound resources, parts, or compound parts. 4. In the Create Group window, enter a Name for the group such as My Group, and click [OK]. 5. In the Logical Collections Tree viewer right click on the My Group group and look at the options on the right click menu. . Note: Notice the Create Group

options.

Note: This group will be stored only in the study and will not affect the original resource tree structure after eMServer Selective Update

is clicked.

Note: You can add both parts and resources to the same compound object. Note:

44


Use groups in various Process Simulate tools to blank/display, create flow operations, create collision pairs, export to Excel, etc ... Groups enable assembly feasibility studies in early stages, even before process is defined.

Create and test the gripper joints and poses

Note: Jump from one pose to the other just to understand how the gripper functions, to find the gripping entities (the pink ones) and to verify it has kinematics. 1. Create the first joint between base and left arm. It should be named j1 and move prismatically along the X axis 2. Create the second joint between base and right arm. It should be named j2 and move prismatically along the X axis. 3. Test the (direct) kinematics and reset them to HOME when done. 4. Add an OPEN pose and a CLOSE pose using the Pose Editor . 5. Jump from one pose to the other. Note: The existence of kinematics is a prerequisite to define any tool. 6. Close the Pose Editor window. Define it as a gripper

1. Select the box_gripper_user## object. 2. Select Kinematics -> Tool Definition . 3. In the Tool Definition window, select Gripper as the Tool Type. 4. Leave the TCP Frame and the Base Frame fields untouched with the values as seen in the picture. 5. Select the cylinders on the gripper as the gripping entities. 6. Leave the offset as 1. 7. Click [OK]. Note: The gripping entities and the offset value define which parts will be attached to the gripper when a Gripper operation is simulated. This is a mechanism that is applied only when the gripper operation starts: It calculates which parts collide with the gripping entities (taking into account the offset) and these parts will be automatically attached to the TCP Frame of the gripper. As a result of this automatic detection of parts to attach, there is a significant importance to the selection of the gripping entities for two reasons:

255


Performance while simulation is running – in order to gain performance and reduce the time it takes to find the parts to attach, a minimal number of entities as possible should be defined as the gripping entities and minimal offset value. o Accuracy – the gripping entity list must include all entities in such a way that all parts that should be attached to the gripper will be found by the automatic detection mechanism. In this activity, we could select only one gripping pair (right or left one), reducing the calculations during the simulation by factor of 2 or even select one entity (if we know the part touches it), reducing it by x4. Due to the fact that both entities and part have very simple geometry, this reduction will not be noticeable anyway. 8. Click [OK] to complete the gripper definition. o

In this case this ―tool‖ would contain the one translational joint and would add flexibility to how the poses could be applied for it. (Otherwise if the bed kinematics were part of the crawler, the poses would contain all the joints of the robot and the bed, making the modification of the simulation difficult). Note: If you are not sure what the kinematics should look like, open crawler_demo and crawler_top_demo, mount it, then Robot Jog it. Delete it from the study when finished.

4. Select Modeling —> Set Modeling Scope 5. Change the Pick Level to Entity.

.


7. Select Modeling —> Create 2D —> Curve on Borders . 8. In the Curve on Borders window for Name, enter Front_Whitehouse_ArcSeams_user##. 9. In the Curve on Borders window, pick the Entity field. 10. For Entity, pick the bottom face of the solid not near an edge.

401


11. Click Preview. Warning: If the curve is not created along the bottom face of this solid, pick it again and click Preview. 12. Click [OK].

402


Note: The new Front_Whitehouse_ArcSeams_user## curve is created in the FRONT_whitehouse weldpart. However, we will not store this change permanently in this part. Instead, we will store this geometry into a separate .COJT related to a continuous MFG feature (in the next page of this activity). 13. Change the Pick Intent to Snap.

Note: In this activity we used the Modeling —> Create 2D —> Intersection Curve command to create the curve. Other commands could have also been used to create the curve. Or the curves can be created in a CAD system, converted to a .COJT, and associated to an existing MFG feature. Create the Arc Continuous Mfg Feature

1. From the Object Tree or Graphic Viewer, select the Front_Whitehouse_ArcSeams_user## curve. 2. Select Weld —> Continuous —> Create Continuous Mfg from Curve . 3. In the Create Continuous Mfg from Curve window, pick the Assign to part field. 4. Pick the BOTTOM_whitehouse_weldpart part from the Object Tree. Note: When we create the arc weld seam the FRONT part will be the side wall and BOTTOM part will be the bottom wall. We derived the curve from an edge of the FRONT part. Therefore, it is suggested to associate the MFG feature containing the curve with the BOTTOM part. Eventually we will associate both parts with the MFG feature, however the MFG will move only with the assigned part. 5. For 3D folder location, click Browse folder.

and select the .\sysroot\Libraries\mfgs

Note: In production, the exact folder name could be anything under the system root folder. However, you should create a standard for what to name the MFG features and where they should be placed.

403


6. Click [OK]. Note: This command will create a new .JT file (in a .COJT folder) that will contain this curve. This .COJT will be associated to a new MFG feature which will be shown in the MFG Viewer. After executing this command we can either delete this curve from the original part (FRONT_whitehouse_weldpart) or just reload the original part. We will do this later. 7. To see the Mfg Feature just created, select View —> Viewers —> Mfg Viewer.

The new Front_Whitehouse_Paint_user##_1 and Front_Whitehouse_Paint_user##_2 curves are created in the FRONT_whitehouse_weldpart only along the front face. However, we will not store this change permanently in this part. Instead, we will store this geometry into a separate .COJT related to a continuous MFG feature (in the next page of this activity). Note: In this activity we just copied the same curve across the part. Another option would have been to create a box that is bigger than the part, move one of its faces to the desired position on the part and then use the Modeling —> Create 2D —> Intersection Curve command to create the curve. Or the curves can be created in a CAD system, converted to a .COJT, and associated to an existing MFG feature. Create the Paint Continuous Mfg Feature

1. From the Object Tree or Graphic Viewer, select the Front_Whitehouse_Paint_user##_1 curve. 2. Hold down the [Ctrl] key. 3.
