  • Auto Cylinder Start Point

    Question - Why Does Auto Cylinder start at the bottom level of cylinder? Yes, I know I can flip the vector of the feature to get it to start at the top but, when programming parts with hundreds of (threaded) holes, this gets tedious. In my head it would…

  • PC-DMIS 2023.2 - Two bugs with the auto cylinder (centering thread scan strategy)

    Hello, I found two bugs with the auto cylinder (centering thread scan strategy). Link to Helpfile -> https://nexus.hexagon.com/documentationcenter/bundle/pcdmis-2024.2-cmm/page/measurement_strategies/Cylinder_Centering_Thread_Scan_Strategy.htm 1…

  • Calculation of one cylinder with diameter constrained is not properly working

    Hello everyone I would like to share with you a little issue I am facing and if someone can advise me about how solve this little problem I have a collection of points (APTs) already radius corrected which are part of one cylinder inspection I'm doing…

  • Constructed Cylinder Glitch from Scanned Cylinders

    Hello. I created two auto-cylinders with 3 levels and as a Adaptive Cylinder Concentric Circle Scan. When you go into a constructed feature there is a plus sign with circle00-01-02. I created one cylinder from these two cylinders as there was a break…

  • Size Dimensioning Fail in ASME

    Trying to dimension the Size of a Cylinder, and I'm getting a "Size calculation failed due to input feature data. Please see the help file." error. This is just a normal Auto Cylinder with an Adaptive Cylinder Spiral Scan. It will let me dimension it…

  • Distance between 2 circles

    So I'm dimensioning the distance between 2 cylinders. The cylinders are in the same workplane, ZPLUS. The cylinders are constructed by 2 circles, 1 at top of bore, 1 at bottom. What is the proper way of dimensioning distance between the 2? From Z-0, the…

  • Measuring from a center point to a radius

    Hi! Im quite new to CMM and PC DMIS, I have a part that has a measurment from one radius of a cylinder to the center point of a circle. I cant manage to get the right dimension, is there a checkbox or something I am missing? Thanks

  • Auto-Cylinder vs Circles Constructing a Cylinder: For Perpendicularity

    Which is more accurate, the auto-cylinder to plane OR 3 auto-circles (constructing a best fit, least squared, cylinder) to plane. Essentially they should have the same result, correct? When I run it I have a 0.0009 difference between the results…

  • Measuring a circle in a teardrop shaped hole

    Hi, New guy here. I have a a cast aluminum block with a cored hole that I need to get correct diameter measurement on. The hole is in the shape of a teardrop. Looks exactly like a teardrop. The hole is currently measured by inserting a gage pin…

  • Perpendicularity of cylinder

    Hi everyone, I am new to the forum and by searching the topics I couldn't find the answer to my question. I need to measure the perpendicularity of a hollow cylinder according to its planar surface used as datum. I have used two different approaches…

  • Core Pin alignment

    Hello, this is my first post and I just have a basic experience with CMM's and PC-DMIS. I am having a hard time figuring out how to align a core pin (see picture below). I have the .IGS model uploaded and I tried to align the part using a cone and…

  • Aut Feature move point promblem

    Howdy. I have a pretty simple and what I imagine to be an easy problem to solve. This has stumped both me and my boss. Anyways, long story short, whenever I try to make an auto feature, such as a circle or cylinder, it adds move points before and after…

  • Old problem and again I struggle...CAD, Cyl shaped part, alignment

    I have a part that basically looks like a Gauge Pin with a hole drilled thru it (90 perp to the longitudinal axis of the cyl). I am having a very difficult time trying to get this thing aligned using CAD. I have tried 3 points on one of the flat ends…

  • Graphic Report of Points, How to recreate this in PC-DMIS

    One of our customers sent us this report. I need to recreate these results, is this possible in PCDMIS??

  • Feature Locations and Directions

    I have a couple constructed features in my program and I want to set correct THEO values for them. Concerning a cylinder, I understand the X and Y values are the center axis, but how does the Z value relate to the constructed cylinder? Is it located…

  • Cylinder Min Value compared to Max Inscribed

    I was asked if the measured max inscribed value of a circle/cylinder should be the same as the minimum value measured for that same circle/cylinder. As far as I understand it, a max inscribed value of a hole is based off of the 3 inner most points…

  • Parallelism of Cylinders

    Please review the attachment. I am having trouble obtaining a correct answer when measuring parralellism of two cylinders Thanks Attached Files Cylinder Parallel Meas.pdf

  • True Position of holes, without Diameter symbol in Control Box??

    let me lay this out for you guys and gals the best I can: I have Datum A wich is a inside Circle recessed into the top of the part. We will call this "Datum A" I have another recessed circle on the bottom of the part. We will call this "Hole"…

  • Cylinder Inersecting Plane Way off Location

    Hello everybody, We have a part that has two mounting studs projecting from two surfaces (mouting surfaces). The drawing specs the distance between the holes & the customer wants the distance between the studs at the mounting surface (actually, opposite…
