Understanding Symbols

Learn how 2D symbols behave in the Resource Manager and drawing, including grouped and page-based behavior, instance scaling, and definition editing.

What to notice

2D symbol behavior comes down to what the placed object becomes: a linked symbol instance, an independent group, or a page-based object that responds to sheet scale.

The Resource Manager is the starting point. Simple 2D square symbols, each marked with a small 2, show how a reusable drawing object behaves before and after placement.

Color coding matters because it predicts behavior. A standard symbol name appears in black. A grouped symbol appears in blue and converts to a group when placed. A page-based symbol appears in green and responds to page scale.

The strongest distinction is between the stored symbol definition and the placed symbol instance. Scaling an instance from the Object Info palette changes that placement. Editing the definition changes linked instances together.

The workflow

Read: Read the Resource Manager before placing

The symbol name color and 2D marker tell the drafter what kind of object is about to enter the drawing.

Black, blue, and green symbol names behave differently after placement.

Place: Check what the placed object becomes

A standard symbol stays linked. A grouped symbol converts into an independent group. A page-based symbol responds to page scale.

The Object Info palette confirms whether the placed object is still a 2D symbol or now a group.

Edit: Choose instance scale or definition edit

Local scaling belongs to the placed instance. Global visual change belongs to the symbol definition.

One placed symbol can be scaled locally while a definition edit updates linked copies.

Resource Manager color coding

Use the symbol color as a behavior clue before placing the object.

  • Black: standard linked symbol.

  • Blue: grouped symbol.

  • Green: page-based symbol.

Editor: Instance versus definition

Separate a local scale change from a definition edit that updates every linked placement.

  • Scale one placed instance.

  • Edit the definition for global changes.

  • Convert only when independence is needed.

One guiding idea

The safest symbol workflow starts by asking what should stay linked and what should become independent.

01 A 2D symbol is a reusable drawing object

A 2D symbol stores reusable drawing geometry so it can be placed, scaled, edited, or converted into different object behavior without starting from raw linework every time.

That matters for scenic drafting because repeated 2D elements should not always be copied as raw geometry. A repeated object becomes easier to place, find, update, and standardize when it lives in the Resource Manager.

02 Scaling an instance does not rewrite the definition

The Object Info palette can scale a placed symbol instance symmetrically or asymmetrically. A two-inch symbol scaled by a factor of two measures four inches in the drawing.

When the symbol component is opened for editing, the original geometry is still two inches by two inches. That is the key: instance scale changes the placement, not the stored symbol definition.

03 Grouped and page-based symbols change the placement rules

A blue symbol name indicates a grouped symbol. When placed, it becomes a group, and editing one group does not change another. That behavior is useful when the symbol is a starting point rather than a linked standard.

A green symbol name indicates a page-based symbol. Page-based symbols respond to page scale, making them useful for documentation graphics rather than real-world model geometry.
