How to make a floor plan in CAD?

Definition of multi-line and building plan

1. Use of multi-line

Format of multi-line

Scale: always set to 1 , zoom in when the size is 1

Alignment: the upper alignment is from the edge of the outer wall as the starting point

If there is no alignment, the center line is the starting point

The lower alignment is within the alignment The wall line is the starting point

2. Knowledge of blocks

3. Building plan

The most basic drawing in construction drawings in architectural design: floor plan

1. Building plan: It is a horizontal cross-sectional view of the house. Imagine using a horizontal plane to cut the house through the door and window openings to obtain the orthographic projection.

2. Drawing steps

Set graphic limits and switch to architectural limits

Define multi-line format (i.e. multi-line format for interior walls and exterior walls)

Draw the outer frame according to the border graphic drawing method

Draw the inner wall along the wall dimensions

Modify the multi-line intersection format

Decompose multiple lines Line and trim to reserve the position of the door

Define door and window blocks, insert blocks

Draw stairs and railings

Insert internal facility blocks

3. Commonly used construction facilities

Doors and windows:

The edge of the door is 250MM or 200MM from the middle edge of the wall, and the door width is about 950MM (single door)

The thickness of the window is usually 362MM, the length of the two-open window is about 1.5 meters, and the length of the three-open window is about 1.8 meters

The outer wall in the picture is generally 360MM, and the inner wall is generally 360MM. For 240MM

4. Complex building plan drawing

Draw the wall marking line (wall axis)

Record the coordinates of the wall line that the wall passes through and draw them in sequence

Drawed according to the general plan drawing method

IV. Home decoration plan

Building plan with clear internal facilities

1. Details< /p>

Some of the items in the picture: can be found in the CAD design center file, and the properties of the objects available for block scaling can be changed.

There are internal facilities in the picture, which means that a certain order does not have them. Most of the dimensions are marked on the inside.

2. Drawing steps

The previous steps are the same as the building plan

The following steps are:

Insert furniture

< p>Filling (mainly walls and floors)

Convert to bitmap

Select color blocks to polish

5. Drawing steps

Determine the picture frame (and set up the environment)

Determine the layer

Draw the graphics

Annotate the text and title block

Annotate the text and title block

Layout

Print

1. Layers

Use layers because complex drawings are often completed by multiple people at the same time. It makes it easy to find different parts of the print and also makes it easier to see the pictures.

General mechanical drawing layers: Layer 0 (outline layer; symmetrical line layer; non-outline layer; filling layer; text layer; annotation layer.

General architectural drawings Layers: wall layer; centerline layer; filling layer; interior facilities layer; door and window layer; text layer; label layer; pipeline layer

Layer management:

On/off. : Not displayed, editable and accessible

Freeze: No...no...no...

Lock: visible but not editable

Building elevations, furniture Elevations, architectural sections and related furniture knowledge texts

Elevations

Project each elevation of an object onto a parallel projection plane according to the orthographic projection method Above, go to the orthographic projection.

1. Building elevation

The drawing mainly shows the shape and shape of the building, the surface material, color and various aspects of the exterior wall. Exterior facilities of the house, etc.

1. Naming: Orientation of the house: east elevation, south elevation, west elevation, north elevation.

Entrance or house appearance: front elevation, back elevation, left side, right side elevation

Axis numbers at both ends: ①~②Facade

2. Drawing:

Draw the horizon line

Draw the outer border of the building

Draw its inner lines

Draw doors, windows, etc. and edit

3. The drawing method of the side view (section view) of the building is similar to this

4. The detailed list of the complete set of home decoration project drawings:

Architectural plan

Special views of home decoration plan (color pictures of various facilities)

Elevation renderings

Ceiling renderings

Three-dimensional renderings

p>

Detailed list of home decoration materials: materials, costs

Final statement of home decoration project: estimate, budget, final account

A set of furniture drawings

2. Furniture elevation

1. Box furniture: (box-shaped) draw the outer frame with straight lines; draw door panels and handrails, etc.

2. Panel furniture: (empty shape) painted wooden boards with rectangular frames.

3. Furniture design principles: can enter the door (width), can be placed into the room (length), can put things in (height)

Abide by the golden section: (length, width) , between high)

Principles of human body work and blood flow: sit high, touch high (touch with hands), lie high (lying high on the table)

4. Basics of home decoration design and production:

Dimensions of common doors and windows

...Material dimensions

...Quotation

...Characteristics: color, reflectivity, Hardness, pattern

...Construction method and on-site surveying (technician) 0?8 Senior home decoration designer

Color perception rate (value represents color, approximate range)

Artistic composition ability

Sense of space (approximate feeling of three-dimensional model)

Annotation and environment setting and layout

1. Annotation

1. The composition of annotations:

Extension lines, dimension lines, dimension arrows, and text.

2. Labeling standards: the dimension line is 2~3MM from the origin

…………3~5MM beyond the dimension line

The text and arrows are in the same size Moderate

3. Marking type

Line type: only mark horizontal and vertical lines.

Alignment: You can mark the slanted parts.

Radius: the part with radian (two radius markings can be used to express the diameter)

Angle: four angles can be marked.

Coordinates: Commonly used on nautical charts, marked Y horizontally and X vertically. Text can also be entered manually.

Circle center: indicates the center of the circle.

Leader: Pay attention to the settings in the leader (type, arrow, attachment, etc.)

Quick annotation: Make multiple quick annotations.

Baseline: mostly used in mechanical drawings (to properly change the baseline spacing should be greater than the text height.)

Continuous: mostly used in architectural drawings (pay attention to tracking and capturing)

Note: Baseline and continuous dimensions should be above linear, radial and angular dimensions.

Tolerance: also known as error, divided into dimensional tolerance and geometric tolerance.

Dimensional tolerance: Symmetrical tolerance: equal upper and lower offsets.

Ultimate tolerance:………varies. (The proportion can be changed when the height is different)

... Size: Calculate the final effect display.

Geometric tolerance: Tolerance of shape and position (commonly used in mechanical graphics)

Building plan: marked with the center line

Home decoration plan: marked with the inner edge Method

Technical operation (apply the label style in another picture to another picture)

The first method: copy method, there should be a new style in the label style to be copied , copy the annotations and paste them into another document.

Second method; drag the desired annotation style into the new document in the Design Center.

2. The use of annotation styles and their modifications

The use of substitutions

The use of modifications (only the parts we want to modify in the annotations)
