    reducing number of segments in polylines

    Just something that I thought you would interesting. LiDAR is synonomous to Radar- where Radar is an acronym for Radio Detection And Ranging. LiDAR stands for Light Detection And Ranging since LiDAR uses lasers (light wavelength) and Radar uses radio waves.

    Tolerance for 4mm a/f hex socket

    Hi, I don't have a perfect answer for your question, however I could find some info that seemed to be somewhat close. In "ANSI B4.2-1984 prefered hole basis metric fits" it says that H8/f7 (close running) fit tolerances for a 4mm hole are 4.000-4.018. Hope that helps.

    GD&T machined octagon centered on shaft

    If you wanted to try using concentricity in this case don't do it directly with your polygon, instead use an inscribed circle in the polygon. That should eliminate some of your problems in displaying positional and relational feature controls.

    Cross Sections

    I use AutoCAD 2004, in that version there is a way to take a section, but it only works if yor drawing is done as a solid model. In a solid model the section command will do what you want, there is also a "slice" command which will take a solid model and turn it into a whole section (just like...

    One drawing on several pages

    One way in which you can is to just work from model space. Put all the items you want to print on one paper together while still in model space and then plot from that. In this method the plot "window" command can be quite usefull.

    How to automatically insert a pre-designed block drawing just?

    I deal with the AutoCAD 2004 program, in that program what you want to do is fairly easy. On the "insert" toolbar go to the "insert block" command, select what you want to put in and just put it there. You could also use the insert pulldown to pretty much the same thing.

    Dimension Roundoff Error

    Your situation may not be so much in the drawing but on the dimensions you are putting on the drawing. You might try adjusting some of the settings (particularly the accuracy and round off) in the dimension style area (go to dimension pulldown, style, modify and then change settings there...

    Runout to threads. Possible??

    I would not want touse a thread as a referance simply for the fact that threads will have more than one precise diameter, would not be a place from which you could take precise measurements and all this could be cause for considerable inacuracy and problems in the shop. Try using a simpler point...

    How to make a line bending at the 2D view intersection of two lines?

    In AutoCAD there are a few ways to turn one line into two, the simpleist is the "break at point" command.

    Flatness or Profile of a Surface?

    The most accurate GDT method you could use for a pipe would be cylindricity, that would provide the most precise control. Cylindricity is probably not being applied in your case for the same reason it is rarely in most cases-that is it is the most difficult feature control to manage. That would...

    ANSI Y14.5 GDT codes

    Has anybody found a website that would give information on the ANSI Y14.5 codes, as well as other ANSI/ASME drafting codes. I have been looking for them on the internet and in the library but so far have had little success. I would appreciate any help.

    Does anyone know of a website that would give informatio regarding the ANSI Y14.5 codes, I've had little luck in finding info on these specs.

    help with dimensions

    The dimension style manager can also be used to adjust the size and shape of the dimension arrows. It can change your dimension arrows from the regular arrows that would be on a mechanical drawing to the tick marks you would put on an architechtural drawing (or a dozen or so other varieties)...

    acad lt 2006 hatch

    One way I sometimes use to hatch a portion of a drawing is to use the region command. Region the section you are trying to hatch, that will make it into one object. Once regioned you can use the hatch command, use the "select object" option and select the region. That should allow you to hatch...

    help with dimensions

    A good way to change the conditions of the dimensions (text size being one of them)is to go to dimension pulldown and select "style". this will bring up the dimension style manager, on it click "modify" this will bring up the dimension modify screen, in it select the text option and go to the...

    ACAD TEXT

    If you dont have the express package the only possible way I can think of to do arc aligned text would be a "manual" sort of way. That is to write each letter as an individual text and the use the rotate command to rotate each letter separatly, This would take a hell of a long time-but if it's...

    AutoCAD 2004, 3-D Springs

    Does anybody know how to create a solid model of a spring using AutoCAD 2004, possibly a LISP for doing this?

    How do you create 3D cables?

    One option you might try is the extrude command, but when you are ask to specify the height don't put in a number instead enter "path" ,then select the pline you want to be the cable this should create what you want. The diameter of the cable will be based on the circle you are you are extruding...

    Is AutoCAD 3D useful?

    I use AutoCAD 2004 myself and I have found that the program has substantial 3-D capabilities, in both solid modeling and surface modeling- the trick is knowing how to utilize it. I had been using the program for years just in the 2 dimensional aspect, I was not aware of its 3-D capacity. How I...

    AUTOCAD CONVERTED FROM EXPERTCAD

    Did you consider that the conversion from one program to another might have caused an incompatibility between the file and your and your printer, it might be worth a try to try plotting your drawing on another printing device.
