Is it necessary to draw the device nozzles first when creating a piping diagram using PDMS? Is it necessary to set the beginning and end of the pipeline first before starting to design the pipe sections?
When laying pipes, it is necessary to first define the start or end of their branches; generally, this starts from a nozzle on a device, or from the start or end of another branch. It is also possible to directly define the coordinate values for the start and end points; once the diameter and type (such as butt welding or flange connection, etc.) are specified, the laying process can begin.
First, it is necessary to determine the route of the pipeline, from where it comes and to where it goes
Let me add more: When drawing tubes with PDMS, it is necessary to define the start and end points, that is, to determine the beginning or ending location. Generally, the pipes inside a device come mainly from the device’s ports ； It can also be defined from a branch – it can be the branch start, the branch end, or a tee; when selecting the start and end, TEE is chosen ； Taking utility tunnels as an example, custom start and end coordinates are required. Sometimes only one of the head and tail needs to be defined, but other times it is necessary to specify the diameter of the other end; the reason for this is not clear.
How is PDMS used?
”Taking the pipe gallery as an example, the custom head and tail coordinates \"are simply a virtual line; when I add flanges to this virtual line, the surface of the flanges is parallel to this virtual line.\" It can’t be turned either, so it’s not possible to draw further. This flange should be able to rotate 90 degrees, right?
It should be said that a point is defined, and then a dashed line appears; the other end of this dashed line is set to zero by default. I don’t know how it happened that the wire and the fittings ended up parallel... Theoretically, they should be perpendicular when connected. Waiting for more updates.
The dashed lines need to be turned into actual models. The fact that they are dashed indicates that there are definitely errors in your drawing. Once these errors are corrected, the flange should be perpendicular to the center line of the pipe. The reasons for the dashed lines could be: 1) the ends are not aligned; 2) the pipe diameters differ. These are the two possibilities I can think of at the moment, so please check your definitions carefully
There is no need to do this. It can be generated directly from scratch using EXPLICIT, as long as the starting coordinates are defined.
Thank you all for your replies. The concept mentioned by the friend on floor 9 is that it’s sufficient to define just one point, right? I’ll give it another try slowly.
It’s not necessary; it can be achieved with hollow tubes. We use PDMS in our work, and those who have questions can discuss them together
