[Managed ObjectARX 2007 with C#]
I am trying to create an arc with start point, end point, and radius. So that if the arc gets drawn, I going to use the center point.
Well, I guess I can use "SendStringToExecute()" or "SendCommand()" and "ObjectAppended" event handler to get the arc object.
Having used another CAD program for several years, I was used to the idea that all radius dimensions, like of a given arc, would easily start at the center of the arc, thereby denoting the position of the arc's center.
I'm slightly bugged with some CAD users, even books on the subject by autocad users, that give an arc's dimension from the outside of the arc, yet fail to show the location of the arc's center when it may not be self explanatory. Not good dimensioning practice from what little I've been schooled...
So, in AutoCAD 2007, how do I get an arc's radius dimension line to start at the center and point out to the edge. I can do all kinds of things to the position of the text, etc, but can't figure how to get it to start at the center. (The dimension line needs to start at the center.)
I'm trying to draw a plan of my house in Autocad 2009 but I seem to be endlessly using trim and extend because I can't easily select the points that I want with osnap. Eg. imagine I have a box, and I want to start drawing another box inside it that has each side as 10 units smaller than the corresponding side on the outer box.
Step 1 - I draw a small line from the top left corner of the big box using the endpoint snap, typing in "5" for the length.
Step 2 - I then do the same at right angles to the first line to get me to the starting point of the inner box. This always leaves me with 2 small lines to remember to delete.
Step 3 - Then in order to draw the top line of the inner box I end up drawing to a random length because I can't say "draw until 5 units away from the right hand side of the big box", then I end up trimming it later once I've repeated steps 1,2 and 3 for the next side of the inner box.
I know in my example above I could have scaled the box down or something but that's not what I'm getting at. I really want a way of selecting line start and end points that are a known position away from an existing point.
I need to draw an arc that starts at a specific point, ends tangent to another line, and has a specified radius. What's the best way to do this?

Currently, the user picks the first point and enters a distance. Then, he has to pick another point (Editor.GetPoint with UseBasePoint = true), I calculate the vector between both points, create a new point (with location = BasePoint.location) and translate it d units in vectorial direction. This works of course, but the problem is, that the user doesn't see directly, where his new point is located, since he may pick a point closer to or farther away then r units.
Naively spoken, I want to restrict the line between BasePoint and new point while prompting the user to a fixed length. Native calls to ObjectARX-methods would be also okay.
I tried to set Polyline.StartPoint to new position (Point3d):
Polyline.StartPoint = myNewPoint3d;
I have "not implemented" exception.
Also, I tried to do it as:
var seg0 = acEnt.GetLineSegmentAt(0);
seg0.Set(newPoint3d(0, 0, 0), seg0.EndPoint);
It doesn't work also. I can do it as:
acEnt.SetPointAt(0, my2dPoint);
But it's 2D point, not 3d
Of course I can remove polyline and create it again, but. How to set start point correctly for 3d point?
I draw a pline. It asks me for the start point. I type in INT. I used to get this 'x' when I was near the intersection. That is now gone. It will still go to the intersection, but I really want my 'x' back.

The only ones I know how to do are they .25 and the .75 diameter. I have tried changing the dimension style in every way I can think of. Just to clarify the 1.31 and .63 radius demotion how the leader starts in the center and the arrow is on the inside of the circle yet the text has the extended leader and is outside the circle and the other radius demotions the text is in the middle of the leader is what I am trying to learn to do.
I want to add say a circle and an arrow at the two ends of a line. I am able to do it using Blocks for one single line by inserting the blocks at desired locations. But how to do it for say all the lines in a drawing or shape file without customization.

View 2 Replies View RelatedI have a problem with absolute and relative coordinate regarding drawing an arc.
From my previous studies, I thought whenever I input coordinates in command line, in order to use absolute coordinates I just enter them. If I want to use relative coord, then I can prefix them with @ sign.
For an arc I input as follows: start point: 0,0 2nd point: 500,500 end point: 1000,0. I was expecting to get a half circle from origin to 1000,0 point but to my surprise I find out that CAD gets the input coordinates as relative.
Am I missing something? 1.dwg1.jpg Is this behavior same for all other object drawings?
I have to draw hundreds of lines that have same start point. How can i do this?
I am trying to insert a picture but seem impossible for me. Sow i have lines with the same start point and different endpoints. There is a short way to do this. so avoid to enter the same start point for hundreds times or snap the the same point infinitely... what about Copy with grips or Change command in this case?
I am trying to create a blend radius between a Line and a Circle, the Blend command does not accept the circle as a valid object.

The question is if I have designed a part in sheet metal with multiple flanges and one of my edges follow a specific radius. Is is possible to use contour roll or any other means to create a flange on that edge that will allow me to flatten that out. I cant see it being physically possible putting a bend in there as the material would need to stretch and the bend tool would need to follow that radius.

I have tried making two point groups "Point #" and "Spot Grades" which include the same points in them with two different label styles for each group, however the point seems to only want to take one label style at a time.

In other words supose I have a block of a simple rectangle with the base point in the center.
If I try to snap to the block, I will be able to snap to all the corners, but not the base point. I know that i can put a point at the base point, but can I turn off the snap to the corners (just for the block) in other words, have an object that is unsnapable to without turning the snap mode off.
