creation of tubing



  • Tim Heeney

    To create a usual ( non 3D spline) inflexible pipe route:

    Draw a line normal out from each device ( pump and valve ) - this is done from a sketch on Center line of each device/part/component.

    Now choose the line command, system asks to select a sketch plane - IGNORE this by pressing the 'D' key or select the icon for soild view. The line command is still active so now connect the previous two lines producing a 3D 'Z' shape.

    Select 'Create Rounded Corner' from Sketch tools - fillet the intersecting lines.

    Now to produce the pipe along it's route ( path). Edit: as Buk says, use Cylinder tool.

    This is the slower 'Pull' method...

    Select the end point ( either end) of the curved pipe route ( when selected, only the end point will highlight ), press 'C' ( Circle) and sketch plane is drawn datumed and normal to line end point. Enter a size. , Press 'P' for pull and select the circle surface ( goes orange ), now choose it's path by selecting the squiggle with arrow icon, double click any part of it's path - all goes blue, press enter or the 'Full Path' (Green arrow with vertical bar) icon.


    Edit: Thanks to Buk.

    I didn't know the Cylinder Tool did routes... It Does !

    Here's the link for more info...

    Selecting a line (or edge) and a point ( or edge virtual point ) then select Insert Plane- great fast way to get a non orthogonal plane and create the connecting path- not req'd for connecting two points ( 3D line does that ) but for a joggle etc, it's essential.

    If you have a situation like this where there is no common point or plane between the two points you wish to connect:

    But you don't want the informality of a freehand spline to connect them; then

    1) place points (in 3D) at the centre points of both connection points:


    Then create two planes by selecting the centre line of one and the point at the other and clicking the plane tool.

    And then a second by selecting the other centre line and point and then the plane tool.

    It should then be fairly easy to plot a path (any of many) between the two using straight lines on a combination of those two planes, just rotate the view and start at both ends,  draw lines on planes and slowly move them together. (It's easier to do than describe!)

    Once you have the route worked out, trim any excess from the lines and use the arc tool to round the corners:

    and then select the route and use the cylinder tool:


    With care, it should work for pretty much any two positions and orientations.
