003-Issues encountered for revit BIM

1. How to built contour in Revit?
Through bringing different level lines/points (ddptype to create different point style)
Insert > Import CAD

Select Item > Split Surface > Drawing Line to split
Select surface > Element Properties

Notes: Orient to View ( referring to elevations/sections)
Civil 3d is for site building with more powerful tools.


2. How to add parking component?
Parking lots are family component in revit, can be added only on flat surface in revit:-
Massing & Site > Mode Site > Parking Component
Massing & Site > Building pad

3. How to create cross sections with complicated contour, site information with existing trees, pub lines?
Separate the file into site drawing & building drawing then link them together to another mother drawing. Create sections/ elevations in the mother drawing for export purposes.

4. How to create property lines/ boundary/ Setback?
Boundary: Massing & Site > Property lines
Setback creating : Masssing Site > Subregion
Planting strips : Masssing Site > Subregion (offset :1m)

5. How to create dimensions?
Create different views then dimension it.

6. How to create view specific items?
Home :Model line vs Anotate:Detail line (View Specific)

7. Revit Elements?
Revit elements are divided to 3 main categories: model elements (built on site)/ Datum Elements / View Specific Elements
-Only View specific Elements are bonded with particular view

8. When a wall is drawn over a column, the column changes into brick, how to avoid that?
Select items>family properties>Category and parameters>family parameters > automatically join > uncheck it

9. Drawing sequence:-

1. Establish the grid
2. Build the walls and columns
One wall type will do ( only architectural wall / columns)
3. After all the walls/columns, change the property to intended wall type
(Change one wall, then match type (match properties) for the rest)
4. Paste align the elements to different levels
5. Insert window and doors accordingly after wall done throughout the levels.
6. Build floor slabs.
7. Build roof
8. Build Ceilings.
9. Build staircase and structure(beam)
10. Build site.( can be linked revit, a separate file for easy access and lighter file size)

Notes: - in revit, no layer concept, only family components which is pre-defined of floors/walls/window/doors….

10. Methodology of residential design:-
1. Build different unit design
2. Build Block Plans with link unit designs
3. Build Building Block with link Block Plans
4. Build Master Plan with link Building Blocks
Master Plan study can be study through changing unit design and update links.
( to be further explored…)

Please feel free to comment. Cheers.

002-Issues encountered for revit BIM

Some simple rendering without any settings done within 3mins.
However, issues faced today as listed below:-
1.How to select overlaid objects?
Let cursor over objects > Tab

2.How to modify doors?
Select Object, Instance properties > Type properties > Duplicate > Change the dimensions

3.How to create blocks/components/family objects?
Create Group(group=family)
Multi-Select > Create Group

4.How to copy selected items with doors/windows/walls?
Error Message:-
“Rectangular Mullion, Rectangular_Mullion_Top_Right ' cannot be added to the instance of ' Model Group, Group 2 ' because of the following reason(s): Mullions and panels cannot be copied without copying the entire curtain wall. “
Group can still be copied. No issue.

5.How to mirror group?
Select items > Modify Model Groups > Modify > Mirror > Pick Mirror Axis/Draw Mirror Axis.
Outcome:-
Once Mirrored, the other group changes as well.
Therefore, group( Revit) = block( CAD).

6. How orbit isolated objects in 2d o 3d?
View > View properties > Extents > Depth Clipping
Or
Select isolated objects > toggle to 3d view

7. How to show different levels in 3d?
Go to 3dview > Right click> Orient to View > Floor Plans > select view

8. How to paste cut objects to different level?
Cut > Modify > Paste align

9. How to join angled object?
Just delete one of the mullions and change the mullion accordingly.

10. How to add annotations at particular view?
When we create annotation, it is view specific items, therefore, we create different views to adopt

11. Orbit in Revit?
Shift + middle click.Revit can only toggle the views in perspective view.

12.How to create associated family elements?
Tag that associated with dimensions?
Tag that associated with 3d?

13.How to render?
Just click the teapot icon at lower corner and adjust the materials accordingly.

14.How to create sheets?
Just Drag the views in and change scale accordingly.

001-Issues encountered for revit BIM

Please rectify me, if there are things missing/unsure/unclear by dropping comments. Cheers.
1. How to create gridlines?
i. Drawing 1st grid then copy, check multiple, then add dimension and change the figure, lock one figure and click the ‘EQ’ to set basic grid figure.
ii. Array your 1st grid, either with 2nd or last checked depending your grid setting purposes. Last one checked is to split the line evenly.

2. How to make link cad files grey tone?
View properties > visibilities display options > imported data > lines color or half tone checked
Or
Select items > Modify items (Top Right Ribbon) > View Graphics > Override
Object’s transparency/ half tone/ color can be adjusted.


3. How to establish dimensions?
Annotate > Aligned
Then click the dimensions
Modify dimensions > Edit Witness Lines > create multiple dimensions (click on the final dimension itself to stop)
To create dimensions, click on the walls and drag to intended position will do.

4. How to measure?
i. Through creating dimension
ii. Modify > Measure > Measure 2 reference / Measure along an element

5. How to snap angled wall?
Manage tab > Project Settings panel > Settings drop-down > Snaps

Endpoints > SE
Midpoints > SM
Nearest >SN
Work Plane Grid > SW
Quadrants > SI
Centers > SC
Perpendicular > SP
Tangents > ST
Points > SX

18. What is the Circular icons and triangular icons?
circular is base point (origin)
triangular (group objects)

000-Issues encountered for revit BIM

Some queries last month for sharing and record purposes for newbies:-

1. How to establish a drawing?
2 basic ways:-
i. Importing from CAD then rebuilt in Revit
- Link CAD into Revit & draw walls, doors/windows to be inserted later. Draw entire straight wall >paste align items to different levels
ii. Create mass in revit then convert into levels, then manipulate levels.
2. How do we control the properties of columns? Changing one and the rest follows? Building columns level by level?)
Select Item > Modify Model Groups > Change Element Type
Or
Select item > Right Click > Element Properties
3. View Icon ( How to call the navigation view icon?)

Shift + middle mouse button
4. Walls ( How to match properties of wall? What is the efficient way of building a walls?
Modify > Clipboard > Match Type
5. How to establish walls?
Just draw, Revit is powerful, all information are incorporated.
6. Curtain Wall?
Home > Curtain Grid > Mullion
7. Staircase?
Home > Staircase

(to be further updated)
8. Locking?
Pin (pp) = locking objects
However, object can still be deleted with prompt.

9. Snapping / Keyboard shortcut?
Revit uses 2letter keyboard short cuts. F1 to look for the alias.
10. Levels?

Levels can be created in Sectional or Elevation view. Respective floor levels are created when you draw the levels out. When you drag and copy the levels, additional steps going to view > create > plan views > floor plan then select respective levels to create the floor levels.
11.Elevations?
View > Create > Elevation
