The Layers and Objects tab is the scene tree: every layer in the document, the objects on it, and the asset library beneath. It is where you select what to style, set draw order, and control visibility.
Layers come from the CAD drawing's layer table, plus any layer you add in Studio. Expanding a layer lists the objects on it. Two nestings go deeper than that:
An object carrying a style override is marked in the tree, so you can see at a glance which objects have stopped following their layer.
| Icon | What it does |
|---|---|
| Eye | Shows or hides the layer. Hidden layers do not export. |
| Padlock | Locks the layer. Locked layers are dimmed and reject edits, moves and deletes, which is useful once a base layer is styled the way you want it. |
Individual objects have their own visibility toggle as well.
| Button | What it does |
|---|---|
| + | Adds a new, empty layer for objects you draw in Studio. |
| Trash | Deletes the selection. Deleting a layer deletes the objects on it, and asks first. |
| ↑ / ↓ | Moves a selected object one step in draw order, or a selected layer one row in the tree. |
| Brush | Paint Style: copies a style onto other layers or objects. Esc exits. |
| List | Show Objects: lists each layer's objects under it. Turn it off to list layers only; see Working by Layer. |
The document arrives in AutoCAD's draw order, so hatches sit behind linework the way they do on the sheet. Every object carries its own place in that order, and that is what decides what draws on top; a layer's row in the tree does not. Change an object's place by dragging it onto another object in the tree, with the up and down buttons, or with Send to Front and Send to Back on its right-click menu.
To stack a whole layer, right-click it and choose Bring Layer to Front or
Send Layer to Back. Every object on the layer moves above, or beneath,
everything else in its viewport or on the sheet, keeping its order against the layer's other
objects, and one Ctrl+Z puts it back. An aerial that was sent to back when the
drawing was styled stays beneath areas painted later, for instance, and a layer of labels
brought to front clears the fills under it.
The tree's own order is yours to arrange. Drag a layer, press Ctrl+Up or
Ctrl+Down, or use Move to Top of Tree, Move Up in
Tree, Move Down in Tree and Move to Bottom of Tree
on its right-click menu, which is the quick way to send a layer the length of a long list.
While you drag, the tree scrolls when the pointer nears its top or bottom edge, and a drop
past the last row lands at the bottom. Layers arrive in alphabetical order.
Double-click a layer's name, press F2 with the layer selected, or choose
Rename from its right-click menu, type the new name and press
Enter (Esc cancels). Every object on the layer follows it, along
with its material, isolation and remembered style. The name box at the top of the layer
properties does the same when you press Enter. A name that is empty or already
in use is refused. An xref layer keeps its xref| prefix; only the part after it
is renamed. The CAD drawing is untouched either way.
Paint Style is the fastest way to spread one finished style across a drawing:
Esc, or click Done next to Paint Style in the status
bar, when finished.| Item | What it does |
|---|---|
| Isolate Layer | Fades every other layer. With several layer rows picked it reads Isolate 3 Layers and isolates them all. See Isolating Layers. |
| Add to Isolated Layers | Brings a faded layer back to full strength without changing the rest. Shown while layers are isolated. |
| Unisolate Layers | Shows every layer at full strength again. Shown while layers are isolated. |
| Rename | Edits the layer's name in place (also F2 or a double-click). The CAD drawing is untouched. |
| Move to Top / Up / Down / Bottom of Tree | Moves the layer's row in the tree without dragging (Ctrl+Up and Ctrl+Down for the single steps). The drawing does not change. |
| Bring Layer to Front / Send Layer to Back | Puts every object on the layer above, or beneath, everything else in its viewport or on the sheet. One undo step. See Draw Order. |
| Material | Tags every object on the layer with a material such as turf, concrete or water. |
| Render as Plain CAD | Opts the layer out of the document look: clean lines, no look shadows or depth shading, its own lettering. See Render Looks. |
| Merge Touching Areas | Joins every group of areas on the layer that share an edge or overlap into one area, so a lawn a line once split shows no seam. Areas made in Studio only; each group keeps its largest area's style. Shown when the layer has two or more such areas. See Merging Areas. |
| Clear All Overrides | Drops every object override on the layer so everything follows the layer style again. |
| Save as Preset... | Saves the layer's style to your global preset library. |
| Save as Project Preset... | Saves the preset inside this project, so it travels with the .asp. |
| Remember Style | Teaches the Layer Style Database how this layer name should look, for future imports. |
| Forget Remembered Style | Removes that memory. Shown only when the layer name is remembered. |
| Delete | Deletes the layer and everything on it, after confirming. |
| Item | What it does |
|---|---|
| Isolate Layer | Isolates the object's layer, or the layers of every selected object when several are selected. Unisolate appears here too while layers are isolated. |
| Edit Path | Enters path-edit mode on a path you drew. |
| Merge Paths | With several open paths selected, joins them into one compound path. They must share endpoints and form a connected chain. |
| Merge Areas | With several areas selected, joins the ones that touch into one area per layer, keeping the style of the one selected first. Also on the canvas right-click menu. See Merging Areas. |
| Unmerge | Breaks a merged path back into its components. |
| Send to Front / Send to Back | Moves the object in draw order. |
| Material | Tags this object with a material. |
| Clear Overrides | Returns the object to its layer's style. |
| Save as Preset... / Save as Project Preset... | Saves this object's style as a reusable preset. |
| Duplicate | Copies the object in place. |
| Delete | Removes the object. |
Clicking a tree item selects it on the canvas and vice versa. Ctrl+Click adds
objects to the selection and Shift+Click selects a range. With several objects
selected, a style change applies to all of them (see
Editing Several Objects at Once).
Layers are styled one at a time; to make several layers match one you have finished, use
Paint Style.
On layer rows, Ctrl+Click and Shift+Click pick several layers at
once for Isolate.
A large drawing can carry thousands of objects. When you are styling layers rather than single objects, turn off Show Objects above the tree and the tree lists layers only.
Ctrl+Click adds or drops another object's layer, and dragging a box picks
the layers of everything inside it.Delete
leaves them alone. The trash button above the tree still deletes the selected layer,
after asking.Turn Show Objects back on to style or move one object. The setting is saved with the drawing, and undo leaves it alone.
Isolating a few layers fades the rest of the drawing so you can work with just those. The faded layers stay in sight for reference, but a click on the canvas cannot select them and the Paint tool ignores their linework. Paint a drainage area from its boundary layer alone, and the lot lines, streets and labels inside it no longer break the area up.
Ctrl+Click for several).Objects selected on the faded layers drop out of the selection when you isolate. Isolation only changes the view. It is not saved with the project, undo leaves it alone, and exports always show every layer. Hidden layers stay hidden.
Below the tree, the Library expander holds two things, chosen with the category list:
The + button imports your own SVG or raster asset into the library. Tiles show one entry per symbol, drawn in the current look's family. Switch the document look and the library previews change with it. See Symbols & Images.
FILE ▸ Stack File imports a second .asp into the open one
for a match line sheet, a detail block or an inset. The preview dialog offers an X and Y
offset, a document size with an Auto-fit button, and a choice of whether
imported layers merge into existing layers or come in with a
prefix on their names. Prefixing keeps the two drawings' layers separate so
they can be styled independently. The whole import is one undo step.
Both projects must use the same units. Stacking a millimeter project into an inch project is refused rather than silently rescaled.
