Node Lines in extrusions
Read 1986 times

If a polyline curved object has been exploded too far, when extruded, the object is displayed with lines where each node is. (not what I want). My question is, can the explode be reversed after the history is lost, or must the construction process be started over again and not exploded too many times.

I do the latter and redraw the arcs if necessary.  Don't know if there is a way to undo the explode.  This is one of the reasons I save all my original sketches.

Hi Rt,
> Auto join polyline the lines
> Convert to curve, here you're going to have to experiment with the convert to curve settings. Sometimes convert to arcs polyline does the job or doing both starting with arcs polyline. The trick is in knowing the method....

After you do  this a few times you'll see how it works creating a smooth extruded object.
Turbocad creates a well defined mesh, sometimes better than TC default extrudes.

Dean was quicker :)

But explode the Ellipse first so everything is Polyline before trim, then Join Polyline, then Select the profiles with Edit tool to make sure they are closed, 1 by 1, then Convert to curve 1 by 1, i set it to 10 mm.
The blue ones did not come out correct for whatever reason, so i delete the original and Mirror copy the red ones, and finally give all a thickness.

BTW, when you offset an Ellipse it will become a spline, hence the other tread about the subject, that is as designed in TC

Another approach: For the absolute minimum number of nodes, I created the elliptical curves as complete ellipses, then cut them as required using Split Entity. Did not use Offset and did not Join Polyline; did enable "Use compound profile" when extruding. The only nodes are at the endpoints of the various entities.

Seems to be a nice option too, but the curves look a bit edged

Yeah; Faceter Quality is only 50 in that screenshot. Here it is with FQ=100...

Or build the panel with extruded complete ellipses and blocks and solid booleans, with no need to split the profiles at all.

That's probably the simplest method of all.

Henry, I reckon that Quick Pull would be the quickest and most obvious method of all.
