Pipe elevation
Thread Content
There is an issue in the work: when drawing in CAD, the pipe elevation is shown as BOP EL100.300, while in the PDS plan, it is shown as BOP EL100300. Should these values be standardized?
It should all be in mm, right? So it’s best to use BOP EL100300 consistently
Agree with the view from the 2nd floor; pipe elevations are generally expressed in mm
In a project, the units should be consistent
Is it a project? If so, it should be unified.
It is not specified which unit should be used for the pipe elevation, but the unit must be consistent, and it should be indicated in the specifications; if possible, the unit for the pipe elevation can be stated after the numerical value
These days, elevations are generally expressed in millimeters. During construction, the elevation is indicated by specifying how many millimeters above the zero level it is
Pipe elevations are still indicated using M.
I’ve never used PDS; I use Cadworx, and everything is expressed in mm there
I agree with the views of those above; they all use mm
For the depth of construction drawings, meters is probably the recommended value
When there is no uniform standard, it is usually indicated in the drawing notes; elevations are generally expressed in meters, while lengths are expressed in millimeters.
There is no need for uniformity; when drawing in CAD, it is generally advisable to refer to the accompanying architectural structure drawings, with elevations indicated in meters. For pipe elevations, BOP EL100.300 is acceptable. When creating plan views in PDS, only the elevations of individual pipes need to be specified, and the length unit should also be in millimeters: BOP EL100300 is also fine.
For the same project and the same unit of length, the elevation should naturally be consistent. As for which unit to use, it is best to specify this in the instructions; for example, state whether the elevation unit for this project is mm or m.
I usually use the pipe elevation for support, and occasionally use the center elevation of the pipe. Uniformity is required on the same drawing.
In our institute, “elevations are measured in meters, while all other values are measured in millimeters.” ” The elevation units in the drawings of a project must be unified, and it is necessary to indicate whether they are relative elevations or absolute elevations. In the case of an outer tube design, it is also necessary to ensure that the elevations in different areas are consistent. We have learned a lesson: it’s very difficult to deal with the situation where the elevation of the pipe joints does not match during construction.
The elevation of j-pipes is generally expressed in mm
It’s not necessary. In PDS, the database administrator determines this at the start of the project, so we don’t need to consider it. Why are many CAD drawings in units of M? It is mainly due to the use of a structural unit system.
