Autocad Draw Polyline Vba Emulator

I have a drawing in AutoCAD 2013 with carefully laid out hatch patterns for traced text using clean, closed, non-overlapping, polylines only. (with islands in the holes). When I import this into Inventor sketch the hatch comes through but the islands do not. Such as the 0 gets completely filled in.

Ok what I need to do is get all the IAcadPolyline objects and change the Fit/Smoth property to Curve-Fit. I can manually do this using Pedit>Fit I know the code for grabbing all the polylines and I could do it using ThisDrawing.SendCommand 'Pedit Fit ' but I can't figure out how to actually get a command sent this way to use a selectionset. I also can't figure out any way to programatically set this property. I searched the help for hours.

HERE Navigation DVD 2019 – Click to Update Your Maps New Maps, Directions, and Addresses The new maps have been updated with thousands of new miles of road, new directions and change to road priorities, the latest changes to business addresses, and also an update to the hugely popular points of interest (POI) database. Research shows that drivers who have the most current maps on their GPS are more inclined to save money in the long-run. Why Update HERE DVD 2019? These are just a few reasons why drivers should buy a cheap HERE 2019 DVD if they want to stay ahead of the traffic and have a positive driving experience in 2019. Toyota navigation update us. This is because they reduce the chances of driving unnecessary miles when lost, can be more effective and fuel efficient, and get to their destination a lot quicker and safer.

I need to change the fit for export to fabriwin when using this setting fabriwin handles splines well but when it isn't set they come through as.25' straight lines that look like crap.) Here is the code I have for grabbing all the polylines one by one. Public Sub ConvertSplines2() Dim m_Data As Variant Dim m_DataType As Variant Dim m_i As AcadObject Dim m_i2 As Variant Dim m_count As Long Dim MyPline as AcadPolyline For Each m_i In ThisDrawing.ModelSpace Select Case TypeName(m_i) Case 'IAcadPolyline' Debug.Print 'm_i is a polyline' set MyPline = m_i End Select Next End Sub.

Corey, this is what I came up with, I had to do a little lame pline conversion so you may not need that line in there. I copied your code too. Seemed to work on a small test. --------------- Public Sub ConvertSplines2() Dim m_Data As Variant Dim m_DataType As Variant Dim m_i As AcadObject Dim m_i2 As Variant Dim m_count As Long Dim MyPline As AcadPolyline For Each m_i In ThisDrawing.ModelSpace 'lame pline coversion ThisDrawing.SendCommand 'convertpoly' & vbCr & 'h' & vbCr & 'all' & vbCr & vbCr If TypeOf m_i Is AcadPolyline Then Set MyPline = m_i MyPline.Type = acQuadSplinePoly End If Next End Sub -------- dragontooths it probably better. Well norrin if you are going to say that:) Corey2 the below will remove LWployLines and replace with 3Dpoly. I did not set thickness so may want to look at that if it is required.

I had to do the.Update for the effects to take I noticed norrin didn't, this is probably version specific, not sure. I also did a regen afterwards, may not be required. Dragontooth's first example was exactly what I couldn't find in the help. It is better than what I was planning on doing as a workaround. I didn't have to regen or anything. REGENAUTO is set to on Autocad 2000.

Now why wouldn't they map that in the help. I searched for Fit-Curve and found a bit of documentation but nothing pointing me toward the type property. The drawing is actually an export from SolidWorks. They all seem to come through as IAcadPolyline(s) so I didn't try to convert the others, but that is added bonus if SW changes the way they export the splines. Norrin you had to do a conversion because they were not spline polylines. I will remember it incase something comes through with the need to be converted. (ps I like the lame pline conversion quite funny) Looking at the Type help page I think I skimmed over it but didn't think it was what I was looking for.

Thanks alot guys. Points to Dragontooth.

Lightweight Polylines 1 Jul, 1999 By: Applications developed before AutoCAD R14 sometimes stumble when they encounter the new objects of Release 14 and later. The most common problem stems from the change in the polyline object inside AutoCAD. AutoCAD R14 introduced a new object named a lightweight polyline that replaces the complex polyline object. When you create a drawing in Release 14 and use commands to create polylines, then you are most likely creating lightweight polylines. From an AutoCAD user's perspective, the lightweight polyline is exactly like the older polyline.
