The Weld tool is used in two completely different cases:
|
|
q Welding different objects together
Welding objects together will transform them in to a single entity (but it will not distort them).
You cannot weld together closed curves and open curves having no common point.
Usage:
1. Select the Weld tool.
Click on the icon depicting the Weld tool in Tools Palette.
The Lasso cursor is displayed when you select the Weld tool.
2. Select the elements to weld.
Select at least one point of each object to weld using the Lasso.
|
Lasso selection of at least one point of each object. |
3. Validating the selection.
Press the Return key to end and validate the selection. The elements are now a single entity.
|
The objects are welded. There is now only one object (entity). The sphere and the cube are displayed in cyan, the color of the current object. |
Welded objects can not be “unwelded”. You must undo the operation (Ctrl+Z on PC; Command+Z on Mac; or select Undo in the Edit Menu) if you make a mistake.
4. Ending the tool action.
Validate or put the tool aside to end the tool action (depending on the interface). See chapter User Manual/Tools/Generic use of a tool/How do you end a tool action?
If, while drawing curves, you mistakenly created two different curves where you wanted only one, weld those two curves together. They will become one single curve. But remember that you cannot weld together open curves that do not share a common point.

q Welding points within an object
Welding points within an object merges the selected points into a single point, positioned at the center of the geometry of the selection. You will thus modify the shape of the object.
Usage:
1. Selecting the Weld tool.
Click on the icon depicting the Weld tool in Tools Palette.
The Lasso cursor is displayed when the Weld tool is selected.
2. Selecting the points to weld.
Surround the points using the Lasso.
3. Validating the selection.
Press the Return key to end and validate the selection. The selected points merge into a single one, positioned at the center of the geometry of the selection.
Selection using the Lasso |
In this example, the four points of the top of the cube are welded together, transforming the cube into a pyramid. |
4. Ending the tool action.
Validate or put the tool aside to end the tool action (depending on the interface). See chapter User Manual/Tools/Generic use of a tool/How do you end a tool action?
You can weld two objects together into a single object, and then weld points of the new single object together.
