Do you have a solution for this? Route spline radius is too small even if it looks like very smooth? There is a tangent relation between a line and a spline. Hose min radius has been set to 13 mm so something does not fit. What is wrong and how to solve this? It is not just one time, it's VERY often when creating a new hose or editing an existing one!
SW 2018 SP5.0
Sound very good!
Please can you explain what is 3D Fit Spline?
A Fit Spline is a single sketch spline that uses multiple existing sketch lines to define it, creating smooth transitions between them.
A 3D Fit Spline is just a regular fit spline in a 3D sketch.
I typically set up the path for my sweeps with multiple 2D sketches on various planes and then connect them together with a fit spline in a 3d sketch.
I'm on 2019, so hopefully this screenshot will do:
Sorry, I don't have the routing add-in, I assumed it worked the same as sweeps.
Have you tried adding sketch fillets between the spline and straight line?
Tapani,
A spline is a curve and there for when you want it to connect to a line it needs to be able to put a tangent relation to it. The only way for it is to either have a straight end to the spline or to make a curve on the end of the line to transistion from one to the other.
Now routing frequently has an issue with dealing with tangents even when there's no need for them. E.g.: complaining about missing an elbow in the middle of a T.
I rarely use tubing so I will have to guess. Have you tried using the 'sketch fillet' function making sure that you're radius is big enough to handle the transistion?
"What is wrong and how to solve this? "
Hi,
have you ever tried to use the "How do i fix this?" in the error message box?
Please try...
Thank you, Heiko, for your reply!
This is a good option, but there are some cons, unwanted effects with that. I have a fastener in the middle of the hose and my connections to this fastener will dissaper when using autofix. And when building a midpoint fastening again, the error comes back to the end of hose ...
And I DO have a tangent relation between a line in the end and a spline continuing there!
Tapani,
I can see that it has a tangent relation on your screenshot. However something is not behaving. So either it has a problem with the tangent or the radius. Neither should be wrong. But one of them must be.
In which case, try to trim a little piece of the bended tube so that it is no longer connected to the straight end and then drag the new end to coincide with the end of the straight. Normally it should automatically snap to it. Afterwards try to put a dimension on the bend (radius) to see if that helps. If not then chances are that the limitations of how the bended tube can adjust itself (the fastener in the middle of the hose) are the root case of your issues.
When you use "Show minimum radius" on the spline - is it smaller as 13mm minimum bend radius?
And: Do you need the check for minimum bend radius? If not, you'll be able to de-activate this in the System Options / Routing / Electric cabling / Enable minimum bend radius check for cables/wires.
To resolve this issue manually, i prefer using the "Sketcher Triad". It's easier then to define the movement of a spline point more accurate. In some cases it's usefull to drag the tangency controls and in other cases i add a spline point. You can reach all this in the context menu of the spline.
Thanks again for a reply but I couldn't get help by unchecking this option. Tested to show min radius and yes! There is too small radius! It's just hard to understand why! A tangent option is set and even a spline point coinsident to the line (dist 40 mm). This should be a radius near infinite to me! Now it shows 2,85 mm in the picture below ... (the error message is from earlier situation after creating a hose. I have adjusted it after that).
I think this is an error in SW ! Please SW fix this!
Looks strange...
What if you close the sketch and then edit it again? Will SWX create the route or will it fail?
And what if you drag the tangency controls (not visible in your screenshot)?
Thanks again!
Can't see any tangency controls, maybe they are not available in routing?
So far I have found it very challenging to use routing with hoses and pipes. I thought this tool has been designed to HELP this kind of works, but for me it has been opposite. I can't spend too much time for this, made a workaround and can get forward. Thank you everyone for your interest and messages!
Have you tried using a 3D Fit Spline for your hoses?
Any time I have tangency issues with sweeps or lofts, a fit spline usually fixes it
