What is the difference between model and layout in CAD?

The main purpose of model space is to create three-dimensional graphics, and the purpose of layout space is to set up two-dimensional printing space.

The specific differences are as follows:

Model space:

1. In model space, full-size 2D graphics and 3D models can be drawn with dimensions.

2. In model space, each viewport contains an object view. For example, setting different viewports will get top view, front view, side view and perspective view, etc.

3. Use the VPORTS command to create viewports and viewport settings, and save them for later use.

4. The viewport is tiled. They cannot overlap and are always adjacent to each other.

5. At a certain moment, only one viewport is active, the crosshairs can only appear in one viewport, and only the active viewport can be edited (pan, zoom, etc.). ).

Layout space:

1, the paper on the status bar has replaced the model.

2. The 2.VPORTS, PS, MS and VPLAYER commands are active. (You can only use the PLAN, VPOINT and DVIEW commands after the MS command is activated. ).

3. The boundary of the space viewport is a solid. You can delete, move, zoom and stretch viewports.

4. There is no restriction on the shape of the spatial viewport. For example, you can create circular viewports, polygonal viewports, and so on.

5. Spatial viewports are not tiled, they can be overlapped and separated by various methods.

Extended data:

Matters needing attention in model and layout space application:

1. Usually, a model composed of geometric objects is created in a three-dimensional space called model space. The final layout of a particular view and the annotations of the model are created in a two-dimensional space called paper space.

2. When working in the model space, you can draw the theme model according to the ratio of 1: 1. When working in a named layout, you can create one or more layout viewports, labels, descriptions, and title blocks to represent sheets.
