Hello,

I have an error when i want to union two solid.

The error is "Error Code Number is 83028".

What can be the solution ?

Thank you for your help.

Here the video and the file :

Hello @Delforge,

Attached dwg file "united", despite being solid entities sometimes have editing problems, usually when they are imported, do not know if this is your case.

I noticed in your file that there are several solid sections joined, I wanted to model the parts again, I drew a line from beginning to end of each section to be joined and I exploited an existing part while keeping the pattern to extrude it following the line.
I used UNION then and it worked correctly.

I leave the screencast of the process.

Hi,

I see that you have a good solution to the problem from @Johanna_Esteban. I observed some additional details that you could use for understanding as well.

When I attempt to UNION the two solids by selecting everything with a window I get the same error you have reported. When I try to UNION by selecting the two solids by clicking on each of them with the cursor I get the same code, unless I have shaded them. With the Visual Style set to Conceptual I get "Error Code Number is 55000" on click-select but still the same error as original with window-select.

By sliding one part away from the other slightly (following the edge direct so they stay inline) I am able to UNION the two (yes parts can be separated and still be UNIONed). Similarly, when I slide one rail into the other by a tiny amount along the linear rail direction they UNION also. This indicated a "super-geeky" problem with how the starting interface is mating up.

I moved one of your solids away from the other by .05 along the linear meeting point. I set my UCS using a 3-point method so as to get a straight view through the .05 gap. I could not readily notice any visible variance in flatness where the two solids meet. I created a boundary of the left face using simple lines and I moved that set of lines into the gap by .025 and the profile appeared flat from a TOP view. However, I set the UNITS precision all the way up to max decimal places and looked at individual line segments to see their X starting and ending points. There is a difference in the start and end points of some of the lines generated from your end profile.

You could dig deeper to find more detail but the fact remains that the interface joint of these "rails" has a mathematical error that is interrupting the UNION command when the rails meet (not a flush joint).

My solutions would be one of the following...

Place a thin cube between the two rail pieces and subtract the cube from both. This will union them but you can use Separate to make them individual again. The I would loft a new solid from the end profile of one to the other, then UNION all three.

OR
Create a bridge piece to span the joint, then move the rails back together so that the bridge piece is occupying the same space in each of the rails, then UNION.

I attached a file showing the profile I generated and the resulting flattened profile. Take a peek at the properties for lines in the top row profile.

Hope that helps too.

Blaine

Thanks for your help. It's work, but i have to do that in VBA !

I have a way, not really to solve that, but to get around the problem.

It worked for me by selecting few items making them as union ,further repeating it till it becomes as single object .
