SOLIDWORKS’ modelling capability allows users to simply and easily model pipe joints. This is made possible using SOLIDWORKS surfacing techniques.
All users need to do to perform such a task is to use the extrude command, surface fill, surface loft feature in SOLIDWORKS and a sketch of the geometry of the pipe. Below are an example.
First begin by creating a part in SOLIDWORKS.
Next, we create a sketch on the top plane representing the axes for the pipes.
Then create planes on the ends of these axes on which we will create cross-sections for the pipes, then use the Extrude surface command to develop the pipe surfaces.
Create pipe sketches and their various profiles using these reference planes
Now it’s time to define the surface loft.
To define the surface loft we need to slightly trim the edges of the surfaces in order for it to loft.
To do this, create a parting line.
Once the triming has been applied, move to the surface tab and select surface loft. The loft parameter requires two edges for the loft feature. The procedures are as follows.
For the end constraints, choose a tangency to face strategy. Follow the same strategy to do a surface loft for the other four edges.
Once you are done you can then use the surface fill feature to fill in the gaps remining. For this particular feature, you only need to define the edge parameters of fill. Move to the surface tab and select surface fill.
Select all the edges associated with the fill. You will notice an envelope is created over this gap. Do this on the bottom face also. Result is a 3-way pipe joint model.
