Initial size of sketch is always too big!

Hello,


Whenever I open a new part, and begin to add features. The initial sketch of the part is always way too big. ie, I sketch a rectangle on my screen, itauto-dimensions tosay, 580x240 inches. I highlight the dims, click the radio dial, lock scale, and dial down to the 1x2 inch range.


So my question... (edit: Using WF 2.0) is there a setting to adjust the "relative scale" of the first sketch of a part to a more appropriatte starting size. Say inches, rather than "hundreds of inches".


Thanks, mark

What version of wildfire are you using. I use wildfire 2.0 and there is an option to set " Units " from inches to mm etc... my settings are always set to millimeters which is " MMKS " prt.
 
Doesn't matter what the units are, the first sketch is always zoomed out to about 600 units. You can turn on the sketcher grid and set the grid size then zoom in to an appropriate area before sketching. However, with the WF2 color scheme I find the sketching grid nearly invisable so I use an alternate technique. I just draw a circle as the first sketch element (even if I have no need for a circle), MMB to quit sketching. The constraint manager automatically dimensions the circle, double click on the dimension and set it to the approximate size of the sketch. The sketch regens and zooms in to an appropriate scale then I delete the circle.
 
hello Again,


Using WF 2.0


dr_gallup understands the issue. This is not about units. Once you adjust the dims of the initial sketch everything is fine from thereon. Was thinking there might be some sketcher 'scale' configoption. I'll poke around w/ grid size. But find the grid annoying so I have never fooled w/ it.


Any help appreciatted. Thanks
 
I don't think there is a "straight forward" way to do it (have looked for things like an "extents" setting to no avail). I put a datum sketch in my templates to accomplish the desired results.

(I'll sometimes use it for some other odd-ball reason like forcing a regen or sizing a model to allow setting a "way out there" model accuracy but most often just put it on a blanked layer or delete it.)
 
I think that will just cause it to rescale after you modify a dimension (as if the option name were vague). It sounds like it already does that for him. I think what he's looking for is a way to have the default sketch scale to be on the order of say 10 units, rather than several hundred units. Unfortunately I don't know how to do that either, but I would like to. I just usually do like dr_gallup and put the first line in and dimension it properly, then continue sketching. It's not highly efficient but it works.

Yeah gallup, I do the same. Might not be perfect but it does the job !
 
Hi morsetaper2,





The reason the sketcher screen view defaults to 580 units, is that it is the size of


the default datum planes. If you 'edit definition' on the planes in your start part,


you can set the size to one that is more common for the size of your work.
 
I tried what NKELLY suggested. It works, but the datum planes are fixedto the specified size and do not grow with the part. Can that be fixed too?


Thanks...
 
I have this trouble as well. I thought it was me and I just put up with it.


After reading these posts this morning I had an idea and tested it. It works!


Do this in each one of your start parts:


Create a curve of a circle of your basic size. Like 5 inches diameter.


Create a new layer and call it whatever you want (always_hidden)


Add the curve to the layer and hide the layer.


Save.


Remove the .1 (or .2) extension and put back in your template directory.





This worked in 2001se.
 
I agree that ProE should have a better way for your first sketch, however there is another solution that has not been mentioned that I use.


Draw you sketch w/o being concerned of the dimension. Once you have completed the sketch, select all the dimensions with the mouse, click the modify value of dimensions. Once the dialog box appears, click lock scale, and then click and modify one of the dimensions. Update, and your part will be the correct size.

Best Idea so far to beat the ProE infamous sketcher scale problem!!!


Give the MAN an applause!!!

Or better yet a standing ovation!!!

No need to see or reference the circle!!!


I renamed mine SCALE so its purpose would be recognized.


Works like a dream in WF 2.0!!!


Way to go kschauer!
 
Hi Kschauer:


Greate job! I was working around it the way Dr_gallup suggested earlier. I believe that's like the universal way to solve the problem. In fact my instructor show me that back in the days.However I most aks this, What's the purpose ofcreating the curve after editting definitions on the plane display? and Would it make a difference if I lock the aspect ratio?

If you adjust the size of all three default datum planes from 500 down to 20 in both directions then the default size in the first sketch will be reduced accordingly. The drawback is that the datums will no longer resize dynamically unless you undo the size settings.

I like kschauer's suggestion to to put a datum curve in the start part. You can always delete it after making the first solid feature. That is quicker and easier than redefining all 3 default datums.

I have added a datum curve in my start parts that is called DELETE_ME and is hidden. This works great. Thanks kschauer!

Yes, it all make sence. Plus we're trying to reduce time and deleting the dtm curve afterwardsis the best way to go.
 
just to add 1 thing what i have done is i added a sketch of a circle and rectangle about 2 centerlines to the first feature and when i start new model I will just edit def seems like 80% of my models starts with one of those


this also serves as a better piece to insert into an assembly rather than just datums


side question-is it possible to change the default name from prt0001 to XXXXX anything?

I don't know how many of you have ever sketched with grids on but......






If your first feature is a protrusion, the default grid size has always been 1 unit per grid square.


If you have datums before your first feature the default grid size
used to be 100 units per grid square but by 2001 this had reduced to 30.


By setting up an appropriate series of mapkeys you can change these
grid
settings (utilities/sketcher preferences/parameters/grid spacing) to
whatever you want making it easy to dynamically zoom prior to sketching
to ensure your first sketch to roughly the right
real size and without tying your initial model dimensions to a relatively limited size range.



To make the grid easier to see, use the 2001 colour scheme

If you draw one line and modify it then all the subsequent geometry will be scaled reletive to that line. Or you can draw the entire sketch and select all the dimensions to highlight them red - then modify one - a box should come up with all the dimensions - there is a check box at the bottom to keep all the dimensions reletive (forgot the title) then modify one of the dimensions and will all resize.
