The letter ‘C’ on the top is a spline, whereas the bottom image is a polyline. In this case, the polyline is more compact than the spline. Image source:TCICorp.com Finally, there are some vector editing actions that you just can’t do to a spline (e.g. changing the width). Of...
Since Revit does not recognize 3d polylines as path for Sweep or Blend (the path must be a spline in revit!!), I have to consider an another workaround. So in order to achieve that goal, I tried to convert my 3d polylines into splines in AutoCAD using controlled vertices. Th...
If the two are not co-planar, it still joins them, though the end result will be a Spline, not a Polyline. If either is a non-planar 3D Polyline, the result will also be, including converting any arc segments in the other one to line segments. But if a planar 3D one is co...
The Helix curve function in Catia V5 only allows a helix on an axis or a line. But there is a trick to create a helix on a spline/curve or polyline. Answered with a tutorial: https://grabcad.com/tutorials/tutorial-how-to-get-a-helix-on-a-spline-curve-polyline-in-catia-v5 Upvote ...
Set it to make polylines. Use Quick Select to select all the plines Region. I think region clears the selection so you use Previous to grab all the plines. Go to shaded mode ("SHADE") to check if there's any tris you missed. Draw some plines and turn them to regions. Quick Select...
To get arcs from splines, try the suggestion in this post. Once the spline is a polyline with arc segments, you can explode it to individual arcs. However they won't join into a circle unless they all; have the same centre point. You've spent several days trying to convert thes...
