Re: Drawing arcs in CADPolyLine manually
Thanks, Sergey.
I asked that because your demo tools don't ignore the bulges in 3D.
I edited a 2D file with bulges inserting Z coordinates (tag 30) and the viewer had unexpected results.
Bye.

Re: Drawing arcs in CADPolyLine manually
Hi Sergey The only information we can share with you can be found in official documentation from Autodesk - DXF Reference: ENTITIES Section -> VERTEX -> Group code 42: Bulge (optional; default is 0). The bulge is the tangent of one fourth the included angle for an arc segment, made negative if the a...

Exporting / importing splines of any degrees
Hi I am using cadimport.net to import and export draw from/to dxf files. Everything is ok but the splines. Actually I can CORRECTLY import/export ONLY splines of DEGREE 3. All other kind of splines are wrongly converted (and it looks like they are managed as if 3rd degree). For instance when i expor...

Using the DXFData structure, I fill - point - point1 - radius - startAngle - endAngle and then I call AddElipse On the file all data are written BUT the angles with the result that instead of writing an arc, i write ...

Well... as far as I know to construct a cubic bezier the control points with the degree are enough. On the contrary with control points and knots I can represent any general spline. I DO have the control points and knots. I just need to write them on the dxf file. Btw: I am developing under MS VS C++

DXFExport.net Spline vs Bezier
Hi. Dxf files can contain any kind of spline, not only cubic bezier. In fact I am able to import any kind of spline, any degree, provided i can read control points AND KNOTS (degree can be inferred). Now how can i write back the same spline ? I have in hands control points and knots, but it looks li...
