As with the original addon, you can add grasping and releasing functionalities to any component.
This updated grasp wizard can trigger the grasping signal automatically based on collisions and servo motions. The grasping logic has also been updated for new functionalities like process modeling assemblies.
Usage
Connect and send a True signal to GraspSignal for grasping and a False for releasing. Check TCPFrameLocation and DetectionVolumeSize if components are not picked up. Grasped components are attached (and following) the Node/Link given when applying the wizard.
Additionally, you can select a servo joint that will trigger the GraspSignal automatically when the servo moves or changes direction past the threshold.
13.06.24 Update: Small improvements and bug fixes.
22.09.25 Update: Fixed an issue with the default detection volume size.
16.10.2025 Update: Fixed Path folder handling for foreign letters.
Installation
Requires access to Modeling tab (Professional or Premium license)
Download the addon package:
Like usual: Unzip the file to your āMy Commandsā and re-launch. E.g C:\Users%username%\Documents\Visual Components\4.8\My Commands
or
C:\Users%username%\Documents\Visual Components\4.10\My Commands\Python 2\
Hello Esta,
A few days ago i installed the grasp Wizard 2. after assinging the true signal it did work.
After saving the program and reopening it, i get two messages and canāt get the grasp function to work again.
Looks like you have renamed the signal name. You can modify the Grasp script around lines 680 to use the new behavior names and then it should work again.
Hello everyone,
Iāve been using the default Grab Wizard so far.
The expert version is more utilized, so Iām going to try using it as the appropriate Add-on.
Unlike the Grab Wizard I used before, many function have been added, so are there any manuals or instructions on what each function means and how to use it?
hello @Este
Is there a way to change and fix the āDetectionVolumeSizeā?
For example, if I change the DetectionVolumeSize to X:70 Y:40 Z:20 during simulation, it works with the modified values.
However, after saving the file and reopening it, the DetectionVolumeSize returns to its default value of X:5 Y:5 Z:5.

Hello, Iāve been using the Wizard you created and it has been very helpful. Thank you.
However, Iāve encountered an issue while using it, so Iād like to ask for your advice.
When I run the sample project āGrasp Wizar2_Errorā,
the Feeder produces a Block Geo stacked in three layers.
But as soon as the Grasp Signal turns ON and it tries to grasp the three-layer Block Geo,
it changes from three layers to a single layer, and the Block Geo is destroyed.
The Block Geo was created as an Assembly in [Process] - [Product] - [Product Type Editor].
This issue did not occur in the previous version, Grasp Wizard1. Grasp Wizar2_Error.vcmx (232.2 KB)
Hello @LEEYONGKOOK,
Set GraspIncludeEmptyAssemblies as āYesā. In the layout, the grasping mechanism forcibly grabs the only product in Step #1 out from the assembly, so steps under Step #1 were deleted.
By using GraspIncludeEmptyAssemblies = āYesā, the mechanism grasps the entire assembly instead of just the one part it detects.
I know youāve been using this edon well, and Iāve carried out a reinstallation of the edon while updating to the latest version of VC 4.10.
As I tried to use it after proceeding with the reinstallation, an error occurred as shown in the attached picture.
I donāt think I can read the path name because the path contains Korean, do you know how to solve the problem?
Ok there is a problem with handling foreign characters in the addon folder path. I made some changes. Please download the new version and test if it works now.
