Exporting to .dwg - Objects with curves

[ArthurADas]

Hi,

I was asked by a client who asked me to export a small hydraulic system in .dwg file format, with isometric view and the system composed only of lines (not 3D solids). The material was then delivered, but it was observed by the customer that the curves contained in the material were exported as a set of lines that, when zoomed, simulate a curve. Attached images.
Is it possible to export the file with these curves being really curved? Plus, i'm looking for the best settings to set to export my Revit project to .dwg.

Obs: The system was made in metric units. The settings to export it was set to metric.

Thanks

Arthur

They asked for lines and got lines. Now they want arcs?

It would be helpful if you shared the original family.

Sorry for the late response.

Since its a small system, i'm attaching the whole file instead of the families.

set your VIEWRES to 20000 in your autocad program and then regenall and see if helps. thanks

Hi, thanks for your answer.

Unfortunately it didnt work, cant even tell if this command changed something at all.

If you wanna give it a try here it is the .dwg file

hello, you cannot do anything because it is not continuous curves, you you have to edit the block by using PEDIT command the select spline. thanks

have you try to change setting from revit when exported to dwg and see what is the outcome. thanks

Hey

I tried this option too. Actually I have tried a lot of option from the exporting settings, keeping the original colors, changing the Solid line to continuous, changed this option that you are suggestion too, etc. But none of them worked 😕
