Good evening all.
I have a problem with this 2nd cross member will not go inside (as the first) between the frames as I wish.
I'm not getting any options in the Feature manager as I did the first member.
I'm sure someone will tell me my issue.
File and screen shot attached.
Thank you . Frank
You have to create one more group for the right post and assign location point for it (red underlined on my picture)
You can use Mirror feature for the right side also.
So your saying I have to create a new group for each post ?
If you want to add in other posts create group for each one and as Igor noted and locate the same way.
With the way you have it modeled, the answer is yes. Depending on where the main planes are located, you could also add one then mirror the rest as Igor suggested.
It's all 3D
OK then change the way you make your sketch.
Want to maintain outer dimensions then offset half the tube size and use the center of the tube to locate the profile; now you only have three groups. You can even write an equation so that half tube size dimension is half of tube profile size so it changes as your tube size changes.
Hi Solid air,
But there shall are additional efforts required to offset sketch and there will be issue in case of rectangular box section instead of square box section.
It is possible to use Move/Copy feature instead.
Yes that is true but it seemed you were against creating more groups which is the easiest solution.
No no. I am not against multiple groups, I prefer to keep the sketch simple instead.
This was done with what the model had.
Main planes were in one corner so creating planes just adds more to FM. time etc.
I like a short FM..
When sketching 3D sketch for these type of things. Simple way is shown in this video.
Great video Maha, but how was it supposed to help me with my currant issue ?
If you can have 3D sketch shown in the video you will not get any issues. It was my finding.
My weldment model is all 3D. I made is as a weldment.

Maha, all tubing is inside the line sketches. Your tubing is on center of lines. So the issue I'm having is locating the post (cross members) inside the lines as the square frames are located.
So on that I think Igor is right.
Hi,
Yes you are correct. It depends on how you locate the profile.
For me, location of profile depends on which dimension is important, if I want to maintain outer dimensions, then I would use your approach, in case if I want to maintain inner dimensions, I would choose other corner, so that sketch lies inside box sections. So, the number of groups shall not be the primary criterion.
Frank,
Another option so you don't have to draw a 3D sketch is use a solid part extruded to the size required, convert the edges to a 3D sketch, hide the solid and then place your structural members on the 3D edges.
Thanks

What is the process for up loading a zip file ?
As I understood some of the other members responses to this tread, I redesigned this weldment and made each part it's own group. This is the only way I could figure out how to position the profiles within the dimension lines as I needed.
But also, I'm now unable to trim this part. And I keep getting a error message : Rebuild Error "Bodies do not trim each other completely. Please check your imput".
So what is the solution to trim this part ?
thank you, Frank
Hi Leatin,
from image, I guess that level/angle are not matching.
Can you check if top faces are parallel and on same level for square and diagonal member.
If you can bring them in same plane, you sould not have a problem in trimming.
You where right. The profile of one plane was slightly higher then the rest. I reset it and it worked. Thank you. Frank
