Easy enough!

Thanks! RE: Forcing an angle dimension on near parallel lines? mloew (Automotive)17 Nov 03 15:12dgallup,

Just a bit quicker than I was on the "submit" button there. Best regards,

RE: Forcing an angle dimension on near parallel lines? 2 KimBellingrath (Mechanical)18 Nov 03 09:24Here's a little clue from my 'Think Like The Programmer' file: This applies to creating features as well as working with simplified reps - It is better to complete an operation in a gross form and then modify it after it is in existance. For difficult features - first create something obvious and then modify it to suit your demands. If it fails, you can cancel the modification. . Same goes with a big assembly; you should create a basic or empty rep to open first. Then if your attempt to open a required rep fails, at least you can cancel the operation and revert back to the 'empty' one instead of having to open the model from scratch.

Hope this helps - I've been learning since Rev 5 and the best clue is to try to think like the programmer "What does he need to know to complete this operation?" instead of "It won't let me..." RE: Forcing an angle dimension on near parallel lines? onlyadrafter (Mechanical)18 Nov 03 11:30Hello,

Surely if you modelled it as an angle, using SHOW/ERASE will show the angled dimension.

maybe only a drafter

but the best user at this company! RE: Forcing an angle dimension on near parallel lines? sundevil98 (Mechanical)(OP)18 Nov 03 12:30The feature was a draft in a hole. I'm trying to show the angle in a cross-section view of the hole.

I tried the Show/Erase function, but it didn't show the angle the way that I needed it to be shown.

I tried changing the draft angle, but wasn't able to regenerate the model.

I've gone ahead and just created a dimension (Pro/E is still trying to give me the width of the hole) and decided to override it and put my own text in (i.e. I switched the @D to @O and wrote in 0.3').

Thanks for the help! RE: Forcing an angle dimension on near parallel lines? im4cad (Mechanical)19 Nov 03 12:42You may try this too:

While dimensioning your draft, pick first the draft's edge, and then use optin "Make Line", and create your second line through a vertex of your choice, and then zoom in and click on the middle mouse button between those two lines to show the angular dimension.

RE: Forcing an angle dimension on near parallel lines? KimBellingrath (Mechanical)21 Nov 03 11:01NEVER! NEVER! NEVER! Create a bogus dimension in ProE!

If you're going to do things like that, just get Autocad.

One of the responsibilities of using a bi-directionally associated model/drawing system is truth in deimensioning. RE: Forcing an angle dimension on near parallel lines? onlyadrafter (Mechanical)21 Nov 03 12:51Hello,

The dimension will be th truth, as long as the value isn't overridden. We do this quite a lot on complex castings where Rad and Draft dimensions do not appear in the correct position. But WE NEVER create dimensions and overwrite what has actually been modelled. Not to create dimensions would take us an eternity to have all the correct views on the drawing.

Hope this helps.

using the words "NEVER! NEVER! NEVER! Create a bogus dimension in ProE!"

Tells me you have not had the pressure of having to have prints out by 3:00 today.

They gave us this option because it is a useful tool.

And I will use autocad style dimensions to get the job done.

as onlyadrafter wrote. They are accurate just not parametric.

and besides it gives us job security :) JOSE FIGUEROA JR. RE: Forcing an angle dimension on near parallel lines? im4cad (Mechanical)21 Nov 03 15:10The vertex is real, is not a 2D feature, and it will regenerate for any change made, so NEVER! NEVER! NEVER doesn't make sense in this topic.

I think who gave you the star shoul take it back im4cad

RE: Forcing an angle dimension on near parallel lines? mloew (Automotive)21 Nov 03 15:50I will not take the star back. Kim's theory on this subject is right on the money, although the accusation in this thread is apparently off base. The philosophy is still star-worthy, IMO. Best regards,

RE: Forcing an angle dimension on near parallel lines? onlyadrafter (Mechanical)23 Nov 03 05:31Hello,

I believe therr could be a way of having thye dimension shown in the correct view, but you will need to redefine the draft and be careful as to which surface you select first. In the drawing find which is the hole in the x-section. if you have put a draft on many, then select one of the two surfaces of the first hole, or the hole in the x-section. If you then erase the shown dimension, if you haven't already erased it. Use show and erase and the dimension should appear correctly.

I'm sure I have done this on some models, but until I get back to work tomorrow, I cannot be sure.

Hope this helps.

but the best user at this company! RE: Forcing an angle dimension on near parallel lines? pkgEng (Mechanical)24 Nov 03 14:36It is quite easy to dimension the angle...

Just zoom in to a point that the two lines are separated far enough apart so that you can click between them to place the dimension. If the angle is very small, then you must zoom in quite a ways. RE: Forcing an angle dimension on near parallel lines? scubadude (Mechanical)24 Nov 03 15:09On the topic of adding a 'bogus' dimension...

You can always use (reference) the actual dim in the text by using the &D#... That way when the dim does change, it will change the 'bogus' dim as well...

Just a thought.

T RE: Forcing an angle dimension on near parallel lines? JBFJR (Mechanical)24 Nov 03 15:43A few years back, I did this to one of my engineers on April fools day. It drove him nuts for and hour or so before I let him in on it. I just forgot how do make a truly 'BOGUS' dim.

For those who really do want to create bogus dimensions, How do you do it? I forget.

Say, I want the dim to read 18. No matter what the actual angle is. Was it something like change the actual dim to "&S"? Then type in 18 as the symbolic. Then in the drawing you would again change the shown dim to &S. The drawing would then show the 18 symbol and you could then change the nominal value to 90 and the dim would still read 18 on the print.

JOSE FIGUEROA JR. RE: Forcing an angle dimension on near parallel lines? JBFJR (Mechanical)24 Nov 03 15:45sundevil98,

Has your original question been answered to your satisfaction?

I would hate to go off on this tangent and leave you guessing. JOSE FIGUEROA JR. RE: Forcing an angle dimension on near parallel lines? Arlin (Mechanical)24 Nov 03 16:02JBFJR:

&D - Default shows dimension Value

&S - Shows dimension symbol

&O text here - is a dimension override to display anything you want. RE: Forcing an angle dimension on near parallel lines? anq (Mechanical)19 Apr 04 09:27Its actually not that difficult. We are using Wildfire and in the config.pro there is the possibility to set the min acceptable angle. We had the same problem as you as i think the default was set as 1 degree and less than this it didnt accept it.

Try it and see if it works.

The config comand is:

minimum_angle_dimension googletag.cmd.push(function() googletag.display('div-gpt-ad-1406030293255-2'); ); Red Flag This PostPlease let us know here why this post is inappropriate. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.

Actually, I have "tol_display" set to "no" in my config.pro file because I don't like seeing the tolerances in the model, but I have it set to "yes" in my .dtl file, and it works fine for me. It doesn't have to be set to "yes" in both.

He had forgotten to change default units settings from Inches to milimeters in model, and afterwards he had created drafting using template with metric dimensioning. We have struggled for a few minutes, final solution was changing model units to mm and starting new drawing.

I have generated a DXF file from Creo Parametric that I am trying to bring into Rhino. The problem is that the dimensions I have added do not show the same in Rhino as they did in Creo originally. The layout of the dimension is changed, and even worse the actual dimension value has changed.

It would make the value pretty unstable to do that since anything that caused enough change in Rhino to cause an evaluation would change the value down the road. I can see that this can be frustrating in this case, but I think it would be as frustrating in other cases if we were to attempt that change.
