possible?... splines to plines?

binary

is there a way to convert splines to polylines?...... not sure if there is a trick in the newer cads....

reason i ask is that i have to turn off osnap when i have imported illust. text lines to cad and they are all splines...... tooooo many vertices and it locks up the puter....

just curious..... would be a good option though

I don't know dude, but if you figure it out let me know. I've been curious about that since this project I did back in January. I usually just end up tracing it with a pline.

spline to pline

, but you'll have to download a lisp routine.

There's a workaround, although a bit complicated. Basically you'll end up with a segmented 2D-polyline (no arcs):

- save the spline in R12 DXF-format
- open the DXF file
- the spline has been converted to a 3D polyline
- explode the polyline to create 2D segments
- use the join command and select all segments to make it into a 2D polyline

...oh yeah, if you are using express tools you can also do Express>Text>Explode Text to convert text directly to polylines.

With Lisp it it is not that difficult, Divide create a number of points along the Spline , so all the app. has to do is to remember the start and end vertex from the Spline entity and then a simple ssget about points on a layer you set before you divide the Spline , will yield an exact vertex list ,except offcaurse the start and end vertex, that Divide don't use.
To draw the 3dpoly or pline , the foreach function are handy, in fact it was more hands-on working with vertex lists and "foreach".
