V/G Overrides for Imported/Linked DWG treats any connected lines as one, disrupting pattern

I've got a floor framing plan that was done in AutoCAD that I'm linking into my Revit model, and using the view template's Imported Categories overrides to change the line types from solid to dashed/center line/joist line etc,  Revit is treating each rectangle (from the DWG) as a single unbroken line, giving me non-aligned line patterns. (attached image)

 

The smaller/shorter joists in the attached image (where the dashed lines are aligned) are correct because I exploded the joists in AutoCAD and shifted the end pieces in 1/64" to get Revit to read them as 4 separate lines, but all the other joists are being treated as one, causing the line pattern override to not be aligned.

 

Is there any way to get Revit to read those joists as 4 separate lines, or do I have to explode and break the corners for it to see them as separate lines?

Can you share the DWG file? I want to see if this is something inside DWG that causes this shift. Normally Revit cannot fix this issue that was caused by DWG.

Here's a part of the DWG file. Linking or importing it into Revit then overriding the layers' line types causes the issue outlined above.

I've looked at your drawing and it seems the yellow layer has a very small angle. Revit may treat that as off axis which cause the line to shift.

It is strange Revit would treat DWG with linetype generation as enable when AutoCAD disable this by default

One way to overcome this is to check on correct line that is off axis.

Once you explode the DWG, the line would display correctly

That's interesting, I've been checking that box to correct off-axis lines, and when I tried what you did (import CAD into Revit, explode to "reset" line patterns), only my A-Flor-Truss lines corrected their patterns. The smaller joists (red and blue in your last picture), remained broken, and when I exploded them all the way down to individual lines, they remain solid - despite the overrides telling them to be dashed.

I've attached the file so you can try it from your end and see if the linetype works for you.

Are the boxes polylines or lines?

 

Worst case, import the DWG in a detail family, explode it, load the family to the project and place it in the framing plan view.

They're poly lines. For now I just made a copy of the DWG and exploded it there, then moved the ends of each joist in 1/64" so Revit would read them as separate lines, then I linked that into my Revit model. I'd just never found anything online asking about this and was wondering if this was a known problem or if there was a better way to do this.

Try my 'worst case' option.

That helped with some of the layers, but some of them still came out crooked or turned to solid lines and wouldn't respond to graphic overrides. Others would update but I had to explode the group, then explode each piece individually since Revit won't allow you to explode multiple items at once.
