RSUVI Posted November 10, 2020 Share Posted November 10, 2020 Is there any way to notch tube to neutral cut like here? So that it would be possible to cut it with laser. Quote Link to comment Share on other sites More sharing options...
rsaucier Posted November 10, 2020 Share Posted November 10, 2020 I know what you are doing and why you are trying to do it. First, let me say that there may be a way to do it, but I have never investigated because of the following. I have a customer that I do a ton of handrails for (and this appears to be a tube for a sloped rail) and they laser cut all their rails. My belief is the laser program compensates automatically for creating that neutral plane. My suggestion would be to check with the company that is doing the laser cutting, but in every project I have ever done, I simply trim the tube so it mates to the pipe. When all done, I send them IGES files of the pipe that is being cut. In 4 years of doing this, I have never gotten a call that a piece did not fit correctly. As mentioned, this is just my experience that a simple trim is all you need but checking with your laser company is your best bet. But I am pretty sure that the simple trim is all you will have to do and the laser program will do the rest. Quote Link to comment Share on other sites More sharing options...
RSUVI Posted November 12, 2020 Author Share Posted November 12, 2020 I need this for tube chassis manufacturing. I would also like to add tabs and slots for easy placement of tubes. Quote Link to comment Share on other sites More sharing options...

A lot of them are angled and mate weird, but I send what it should look like and they have no issue making the part and it always fits up. -Spencer Quote Link to comment Share on other sites More sharing options...
tlehnhaeuser Posted November 12, 2020 Share Posted November 12, 2020 (edited) Whould something like this work for you? Revised for angled end cut. This approach uses Design Variations and SmartAssembly. Edited November 12, 2020 by tlehnhaeuser Saw it should be angled 1 Quote Link to comment Share on other sites More sharing options...
rsaucier Posted November 12, 2020 Share Posted November 12, 2020 Here is a short video on how you can add a tab to a sloped and trimmed tube. You can actually take this feature and put it into a catalog for future use so you d o not have to keep recreating. . I will attach that next.

rsaucier Posted November 12, 2020 Share Posted November 12, 2020 Here is an example of how you can reuse the tube at a different angle without having to recreate the sketch. TabRotate.mp4 1 Quote Link to comment Share on other sites More sharing options...
rsaucier Posted November 12, 2020 Share Posted November 12, 2020 Finally, here is an example of how you can use the catalog to reuse the tab. hope these help. ReuseTab.mp4 1 Quote Link to comment Share on other sites More sharing options...
RSUVI Posted December 14, 2020 Author Share Posted December 14, 2020 (edited) Well i found a way how to do it, but can there be any quicker way? Edited December 14, 2020 by RSUVI Quote Link to comment Share on other sites More sharing options...
Malcolm Crowe Posted December 14, 2020 Share Posted December 14, 2020 (edited) For your interest, attached is a video demonstrating a method where the outside faces of both parts mate. The steps include the following: 1. Intersection 3D Curve between the original CHS Parts 2. Splitting of Outside Faces of the CHS Parts (using the above Intersection 3D Curve) 3. Selecting the unwanted split faces and using the Thicken Tool to create trimming parts 4. Using the created Trimming Parts above trim the original CHS parts We also use trimming surfaces (created normal to outside face) in some situations.

Malcolm Crowe Posted December 14, 2020 Share Posted December 14, 2020 (edited) For structural applications where only the branch CHS part is being trimmed, the process is as follows: 1. Intersection 3D Curve between the outside faces of both CHS Parts 2. Intersection 3D curve between the inside face of the CHS part to be trimmed and the outside face of the other CHS part 3. Splitting of Outside Face of the CHS Part to be trimmed (using the outside Intersection 3D Curve) 4. Splitting of Inside Face of the CHS Part to be trimmed (using the inside Intersection 3D Curve) 5. Selecting the unwanted inside split face and using the Thicken Tool to create a trimming part 6. Selecting the unwanted outside split face and using the Thicken Tool to create a trimming part 7. Use the Boolean Subtract tool to subtract the created Trimming Parts above from the CHS part to be trimmed 8. Add a blend (such as CHS outside radius) to blend the transition between the inside and outside trimmed sections Malcolm Trimming Intersecting CHS - Normal to Inside and Outside Faces.mp4 Edited December 14, 2020 by Malcolm Crowe 1 Quote Link to comment Share on other sites More sharing options...

Malcolm Crowe Posted December 15, 2020 Share Posted December 15, 2020 The previous videos demonstrated the principles involved. This video demonstrates how you can use these principles to create a "Trimming Part" to simplify the process. Here we've created a multi-bodied "Structured Part" (as opposed to an Innovative Part), so that we can toggle between different bodies for trimming any of the following: - Branch Inside Intersection - Branch Outside Intersection - Main Inside Intersection - Main Outside Intersection This is a good example of how "Structured Parts" can be used to assist when modelling "Innovative Parts".

Malcolm Crowe Posted December 16, 2020 Share Posted December 16, 2020 If wanted, you can use an "Offset" within the "Trim" feature to create a welding gap as well.

RSUVI Posted February 1, 2021 Author Share Posted February 1, 2021 (edited) Malcolm, you are the KING! Thank you very much. Very helpful videos. Can you share the trimming part file? Edited February 1, 2021 by RSUVI Quote Link to comment Share on other sites More sharing options...
Malcolm Crowe Posted February 9, 2021 Share Posted February 9, 2021 (edited) For the purpose of helping demonstrate how multi-bodied "Structured Parts" can be constructed and used to help with "Innovative" modelling, I've attached the requested Trimming Part file (as used in the above videos). I hope that helps. Malcolm CHS Intersection Trimming Part.ics Edited February 9, 2021 by Malcolm Crowe Quote Link to comment Share on other sites More sharing options...
