Input

• Group containing one face, several faces, or surfaces.
• Group containing one edge path that is closed.
• Group containing points.

Operation

Direct

1. Pre-select valid inputs.
2. Run Fit.
3. To adjust result, type values.

To finish, switch to any other tool.
To keep Fitting, continue to item 2, below.

Alternatively:

Picking

1. Run Fit with nothing selected.
2. While running Fit, Pick valid inputs.
3. To fit, click Enter or Doubleclick.
4. To adjust result, type values.

To finish, switch to any other tool.
To keep Fitting, repeat from item 2, above.

While running, type VCB values anytime.
Values control active result, and next result.

Options

• Hold Shift = Toggle selection.
• Hold Ctrl = Add to selection.
• Hold Ctrl + Shift = Subtract from selection.
• Enter or Doubleclick = Apply selection.
• Click = Select.
• Drag Rightward = Select enclosed.
• Drag Leftward = Select within.

Masking

• You may limit the Fit effect to only a smaller area within a larger input. To limit, use a Mask. A Mask, sometimes also called "Area filter", is useful to restrain change to only a certain part of the terrain.
• Only containers with a clearly defined area can act as masks. Currently, this means one single face, or one closed path. The path does not need to be planar.
• Only one area can be active at a time.
• If you have several inputs selected, Landshape will automatically identify the smalles area as the active mask.
• In pickphase, the current mask is highlighted in magenta.
• To explore masks, try starting Fit with nothing selected. Then select multiple overlapping area inputs. For details, see Operation, above.

Try Fit Hands-on

• Simple – [...]]
• Intermediate – [...]
• Advanced – Plot a terrain. Select it. Quake it. Select it. Run Prop > Clone Vertices. Hide the resulting pointcloud on a tag. Run Draw. Draw a simple path on top of the undulating terrain, making sure the path is closed by finishing the drwing at the start. Use e.g. Grab Brush or other tools to reshape the terrain. Make both the pointcloud group and the bounds group visible. Select both groups. Run Fit. The result should be that the terrain heights are reset to the state of the the point cloud within the the area enclosed by the path, while the rest of the terrain remains unaffected. This technique can be useful to save states of the entire terrain, and to locally bring back a previous terrain height state.

Tips

Using filters

You can fit to a subset of your input target. To do so, first create an area filter. You can use e.g. Draw to draw a closed bounds, or make a single face and group it. This will be your area filter. Then, select the area filter and the larger input group at the same time. If the input and the area filter overlap, the area filter will limit the fit to the area filter.

Fitting to a clone

If you have a terrain shape that you wish to be able to return to later, you may Clone Terrain Surface or Clone Vertices. Use an area filter to limit what you extract. You may temporarily hide the clone on a separate tag. To reapply the previous shape at a later stage, show and select the clone, select any input area, and run Fit.

Working with input geometry in Pick commands

Landshape is a toolsuite that turns terrain into a plastic canvas, empowering you to impose your vision onto the terrain.

Landshape's Pick commands – in contrast to its more expressive Brush and Draw tools – let you edit and interact with the terrain using persistent control geometry, also known as input geometry, or simply input.

You may at any time edit your input geometry, using any method you like. You may use Sketchup's built-in tools to edit its e.g. faces, edges, points. You may also edit e.g. the position, rotation, scale and material of the input group itself. Then, you may select the input and run a Landshape command again.

Thus, input group geometry embodies information that you can apply to your terrain at will.

This workflow enables good repeatability, great control, and complete accuracy. You may keep input geometry for later use. You may copy input containers to several positions in the terrain. You can create input variants, and organise them onto different tags.

In sum, use input geometry to drive terrain change.

Cloning

The complement to input geometry is Landshape's Clone commands. These commands go the other way. They extract information from the existing terrain, and embodies it as standalone geometry. Then, you may edit the standalone geometry using e.g. Sketchup's built-in tools. Or, you may store away the terrain information in a tag. Then, you may retrieve and apply it at another point in space or time.

In sum, use Clone to copy aspects of terrain states for standalone editing, storage, and reapplication.

No need to select terrain

To shape terrain, you never need to select terrain. If you have selected valid input, Landshape will detect its corresponding terrain plots automatically.

Should you happen to have terrain selected along with input geometry, Landshape will produce the same result as if you had only selected non-terrain input.
