Draw Line

  1. Click on the pencil icon or type keyboard shortcut <D>.

  2. Left-click on one side of the bench, outside the boundary line.

  3. Left-click on the other side of the bench, outside the boundary line.

  4. Press <ESC> to finish.

During drawing, the <Backspace> key works as an Undo hotkey.

Move Point

  1. Click the point-move icon or type keyboard shortcut <F>.

  2. Select a point on a line.

  3. Click the new point coordinates to move it there.

Construction lines must form a closed polygon into order to cut solids. This means they must cross another line, or cross through the border polygon.

Offset Lines

  1. Click the line-offset icon or type keyboard shortcut <O>.

  2. Select a line to offset (this may include the bench boundary polygon).

Trim Lines

  1. Click the line-trim icon  or type keyboard shortcut <T>.

  2. Click on a line to trim it back to the nearest intersection.

The Trim tool may not detect an intersection where two closed polygons form an adjacent corner. For these cases, use the Break tool to clear the segment.

Delete Lines

  1. Box-select all lines in the viewport (they will become blue).

  2. Press the <Delete> key or the Delete icon.

Excluding Solids

Even if you have solids selected, the <Delete> key will not delete them (solids). The only way to remove solids is by toggling the Force Exclude property in the Properties panel.

Excluded blocks will be hatched according to the Hatch pattern set in the Setup > Setting.

Undo / Redo

There are two ways to undo/redo changes made in the Designer tab:

  1. Left click in the 3D viewport to activate the area.

    1. Press <CTRL> + <Z> to undo the last change.
