Editing

Modify your structural model with these editing operations.

Undo/Redo

  • Ctrl+Z - Undo the last action
  • Ctrl+Y - Redo the last undone action

The undo history is preserved until you close or reload the page.

You can also use the Undo and Redo buttons located in the top left corner of the screen.

Delete

Select items and press Delete to remove them:

  • Deleting a node also deletes all connected members
  • Deleting a member leaves the nodes intact

Alternatively, right-click on the selected items and choose Delete from the context menu.

Move

  1. Select the items you want to move
  2. Press W to enter Move mode
  3. Click to set the base point
  4. Click again to set the destination, or enter coordinates

You can also activate the Move tool by clicking the Move button in the left toolbar.

Intersect Members

If two or more members intersect, we can select them and create nodes where they cross:

  • First, select the members that are intersecting
  • Press X
  • You can also right-click and select Intersect from the context menu.

Loads on affected members are automatically redistributed across the new segments. Section, material, and design properties are inherited by the new segments.

Split Member

Split a member at its centre point, creating a new node:

  1. Select the member(s) to split
  2. Press B
  3. You can also right-click and select Split at Midpoint from the context menu.

Loads on affected members are automatically redistributed across the new segments. Section, material, and design properties are inherited by the new segments.

Divide into Segments

Divide a member into equal-length segments (up to 12):

  1. Select a member
  2. Right-click and select Divide into Segments from the context menu
  3. Enter the number of segments (2–12)

Loads on divided members are automatically redistributed across the new segments. Section, material, and design properties are inherited by the new segments.

Merge Members

Merge two or more collinear, connected members back into a single member (inverse of split/divide):

  1. Select the members to merge (must be collinear and form a continuous chain)
  2. Right-click and select Merge Members from the context menu

Loads on the original members are automatically repositioned onto the merged member. Interior nodes (and their restraints) are removed. If the selected members have different sections or materials, a warning dialog appears before proceeding - the merged member inherits properties from the first member in the chain.

Edit Properties

Select items and use the Properties panel to modify:

  • Nodes: Edit support conditions
  • Members: Edit section, material, node fixities
