Trim 2 entities keeps wrong side.

anybody else seeing this since the trim preview

was introduced.

 

Does turning off the troublesome trim preview stop

trim from keeping the wrong side?

 

Getting tired of trimming 2 entities and it

keeps the wrong piece of one of the entities.

It happens 50% of all trims

 

so, I....

-exit out

-hit undo

-trim using break

-delete the unwanted pieces

-exit out

 

If it does fix the bug, how do you turn off

the preview?

 

Thanks in advance

"... how do you turn off the preview?"

 

Settings - Configuration - CAD Settings (page) - Enable Trim Preview (lower-left corner of the page)

Roger, is this going to be fixed?

I am one who likes the preview.

 

Thank You

I'm sure I don't use trim as much as some in here but it's a very rare occasion that I get the wrong end. I still have the preview turned on.

just had this problem today. Could not get it to trim the correct side. I have trim preview off.

 

some choice words were spoken today.

Turning off trim poreview didn't fix the trim problem for me, maybe X5 is the answer.

I've had this happen with arcs a number of times. One thing that helps is Combine Views under Screen.

Another trick is to break at intersection. I have a bug tag floating around related to this subject.

 

another one is to change trim to break at point. Then create a point where it should break and sometimes that is the only thing that will work.

[3R!< W3NG3R]

Crazy, I tried both of those tricks and they wouldn't work today.

 

I was just doing some containment boundaries where lines did a good enough job. Frustrating I tell ya.

I have had trouble just trimming 2 lines that intersect. I had to extend the lines so they overlap and then the trim worked

Same here, 50% of the time.

X2 trims just dandy! :/

 

Trim Preview? Read about it. Never had the pleasure ever using that option.

 

99% of all trimming done in X2. On rare occasions I use Rhino, but not recently. I like Rhino sometimes when splitting surfs..

The 'ONLY' thing I miss about X2 now that I can't

get X4 to Crash

[JDowe]

It helps to be in 2d and the corrsct plane when trimming

Yeah wait for a fix in X5, break out another $10,000 for maintenance hahaha

I have never used Screen / Combine Views. What does it do?

Are you sure they weren't splines? Splines won't trim (and extend) past their end points. You must first extend them so they cross each other, then trim them back. Lines will extend OR shorten when being trimmed.

Im sure they were lines. Some of them worked and some did not. I did get them to trim but like i said i had to extend lines so they overlap each other. Which should not have made a difference.

Thad is Correct but they also sometime keep the

wrong side as well, after doing all the above.

It takes circles and arcs that may be on different parallel planes (like top and bottom or left and right) and sets them all to the same plane without physically moving them. Trimming doesn't like arcs with different parallel planes.

I have had the same problem in X3 MU1. What I have found that works as a solution is this. Pick each element farther away from the point of intersection. Usually has to be more than the amount the elements are being extended or shortened. This works at least 99% of the time.

 

Thad is correct too that unless a spline is already past the (theorectical) point of intersection it won't work.

 

Lines and arcs do not need to be extended to create an intersection, but splines do.
