Angular dimension - Change zero to vertical

YannickEnrico — Tue, 23 Oct 2018 07:47:05 GMT

Hello there

Is this is a possibility without having to create a sketch to make a reference vertical line?

A saw where I come from is often marked 0 degrees when it's perpendicular to the profile direction, rather than 90 degrees. That -can- create confusion for people, which is why I was looking for a solution that wouldn't involve me manually drawing a vertical reference line

I don't see how you can do this without a vertical line, the angular dimension needs that vertical reference otherwise it has nothing to attach to.

Yeah, I know. I was just wondering if there was a setting so it would auto create such a line, or something. Otherwise I'll make a suggestion.

@NigelHay is correct, you would have to draw the line. We used to do this until fairly recently, at the insistence of the previous manager of our fab shop. After conferring with the current manager, it turned out that the extra work was of questionable benefit.

As I recall, it turned out that not all of our equipment was labeled the same way, so it actually wasn't possible to pick a dimensioning convention that suited all of it. There may have actually been cases where it caused new errors when the fabricators used different tools than we expected them to, and they used the number on the print anyway.

We ended up reverting back to just dimensioning the interior angle of the part, which is easier for the drafter and is easier to measure if the part is inspected after it is cut. It is then considered the fabricator's responsibility to make whatever adjustments are required to get that final result using the tools he chose to use.

Just my experience with it - you may have a more consistent situation where a standardized convention would work out better than it did for me.

Hi Guys,

I think this is probably more about the lack of Angular Ordinate dimensions. Indeed, I have heard the request before but we don't have a solution yet unfortunately.

Many thanks!

I don't think this is about angular ordinate dimensions, Johnson. The right end of the lower view of @YannickEnrico's drawing image is what he's asking for. The upper view merely illustrates why this kind of dimension is needed: the typical layout of the angle scale on a miter saw corresponds directly with that angle dimension, which Inventor can't produce without creating a sketch.

@jtylerbc - I'm working for a small blacksmith, and we have one saw, which is why my suggestion would work perfectly fine for us. I'm aware it can create confusion if we have to request parts made elsewhere, which is why I wouldn't necessarily use this kind of dimensioning all the time.

@johnsonshiue - @SBix26 is right. The dimension is needed to avoid confusion in the cutting process. I'm aware it's just a question about taking 22,5 from 90 in order to convert - However, at my workplace, that seems to create more confusion than necessary.
An option to easily (which means not creating a vertical line on a sketch myself) create this sort of dimension would really be nice. At least on frame members, seeing as it's not a necessity on sheet metal, plastic parts or otherwise CNC machined parts.
