Im just starting to get my head around VBA in AutoCad. I have managed to write a code that creates a 2D truss in polylines by coordinates I have arranged in an Excel file. Now I need to extrude each member into a cylinder. Well Im not really that smart yet, having some hard time with choosing path and region.
View 9 RepliesIn inventor 2013 I want to extrude a horizontal circle on surface of a bigger vertical hollow cylinder. but what i did it enters into cylinder, and i only want to extrude it on external surface.
View 1 Replies View RelatedI'm trying to extrude a circle around a path in all dimensions, so I drew my path in lines, filleted the corners then tried to join using the PEDIT - Join command.
Firstly, the join says something like "2 segments added to 2 polylines" when really all I want is 1 polyline.
Second, when I try to insert my circle for extrusion I OSNAP to the end of the line, then when I specify the radius it draws in the wrong plane. So far the only way I have gotten around it is rotating the ucs. Is there an easy way to do this? my Dynamic UCS is on.
How to stop the UCS from automatically turning to world when extruding a circle?
Example: If you start with a circle drawn to your set 3 point UCS the quadrants are in line with the X & Y but as soon as you extrude the circle into a cylinder the UCS turns the quadrants to world, I want the quadrants to stay in the same place as my 3 point UCS position.
Not sure if it's just a system variable that need changing.
I'm trying to change a routine i just wrote that draws 3d pipes. I wanted to make it so that when a user selects the beginning point and ending point of the pipe, the LISP changes the ucs to that vector, draws the circle at the beginning point and extrudes it to the second point.
It actually works great except when the ucs changes, so do my user points because of teh origin change. Is there a better way I might get this to do what I wnat it to?
(setq ip (getpoint "
Pick First Point:"))(setq ep (getpoint "
Pick Second Point:"))(command ".ucs" "za" ip ep)(setvar "osmode" 0)(command ".circle" ip "d" od)(command ".extrude" (entlast) "" (distance ip ep))(command ".ucs" "w")(setvar "osmode" oldsnap))
When I extrude/bevel a perfect circle (Illustrator CS6 Mac), there is a defect visible on the edge of the circle. Please see 4 images attached. Is this normal, and is there a fix or workaround?

I am not sure what is wrong .. but i heard parallel and perspective view could make a difference .. i actually try both :/ ...

I have tried to go through the same steps, but I can not select the inside of the rip to built hems and flanges on. I also tried to make the cylinder by sketching 350 degrees of the cylinder instead of creating a rip, This had the same problem.
Why I can't select these edges or how I can work around it?

View 9 Replies View RelatedI have a tube modeled in AutoCAD that is 1.5" OD and 1.25" ID. Along with it, I have a piece of flat 2D geometry representing a pattern to be cut into it.
Is there a way to either wrap the geometry around the tube and extrude out the shapes, or a way to extrude the geometry to the correct thickness and wrap it into a 1.5" OD tube?

I want to do a simple bend of a cylinder. That is, I have made a 40inch length and want to bend it at several places.
I keep finding a reference to bend part but the tool does not exist in Inventor.
1. I would like to scribe number of lines in axial direction & around the circumference of a cylinder
2. Secondly, I want those lines to be visible on .idw file so that I can print my drawing
I have a telescoping cylinder that someone else modeled. It has an extended and retracted positional rep. I want to make it free moving so that is will move in and out inside another assembly. I can get it to move freely and stop at it's extents using contact sets. My problem is that when you jump from a retracted position to an extended position the center rod "escapes" from the housing.
